Should be valid HTML markup with following classes used to inject printing values into them: `date` (formatted print date), `title` (document title), `url` (document location), `pageNumber` (current page number) and `totalPages` (total pages in the document). For example, `<span class=title></span>` would generate span containing the title.

+### Using electron-winstaller (Squirrel.Windows)
+
+[`electron-winstaller`] is a package that can generate Squirrel.Windows installers for your
+Electron app. This is the tool used under the hood by Electron Forge's
+[Squirrel.Windows Maker][maker-squirrel]. If you're not using Electron Forge and want to use
+`electron-winstaller` directly, use the `certificateFile` and `certificatePassword` configuration
+options when creating your installer.
+
+```js {10-11}
+const electronInstaller = require('electron-winstaller')
+// NB: Use this syntax within an async function, Node does not have support for
+//     top-level await as of Node 12.
+try {
+  await electronInstaller.createWindowsInstaller({
+    appDirectory: '/tmp/build/my-app-64',
+    outputDirectory: '/tmp/build/installer64',
+    authors: 'My App Inc.',
+    exe: 'myapp.exe',
+    certificateFile: './cert.pfx',
+    certificatePassword: 'this-is-a-secret',
+  })
+  console.log('It worked!')
+} catch (e) {
+  console.log(`No dice: ${e.message}`)
+}
+```
+
+For full configuration options, check out the [`electron-winstaller`] repository!
+
+### Using electron-wix-msi (WiX MSI)
+
+[`electron-wix-msi`] is a package that can generate MSI installers for your
+Electron app. This is the tool used under the hood by Electron Forge's [MSI Maker][maker-msi].
+
+If you're not using Electron Forge and want to use `electron-wix-msi` directly, use the
+`certificateFile` and `certificatePassword` configuration options
+or pass in parameters directly to [SignTool.exe] with the `signWithParams` option.
+
+```js {12-13}
+import { MSICreator } from 'electron-wix-msi'
+
+// Step 1: Instantiate the MSICreator
+const msiCreator = new MSICreator({
+  appDirectory: '/path/to/built/app',
+  description: 'My amazing Kitten simulator',
+  exe: 'kittens',
+  name: 'Kittens',
+  manufacturer: 'Kitten Technologies',
+  version: '1.1.2',
+  outputDirectory: '/path/to/output/folder',
+  certificateFile: './cert.pfx',
+  certificatePassword: 'this-is-a-secret',
+})
+
+// Step 2: Create a .wxs template file
+const supportBinaries = await msiCreator.create()
+
+// 🆕 Step 2a: optionally sign support binaries if you
+// sign you binaries as part of of your packaging script
+supportBinaries.forEach(async (binary) => {
+  // Binaries are the new stub executable and optionally
+  // the Squirrel auto updater.
+  await signFile(binary)

+slug: distribution-overview

+---
+
+Once your app is ready for production, there are a couple steps you need to take before
+you can deliver it to your users.
+
+## Packaging
+
+To distribute your app with Electron, you need to package all your resources and assets
+into an executable and rebrand it. To do this, you can either use specialized tooling
+or do it manually. See the [Application Packaging][application-packaging] tutorial
+for more information.
+
+## Code signing
+
+Code signing is a security technology that you use to certify that an app was
+created by you. You should sign your application so it does not trigger the
+security checks of your user's operating system.
+
+To get started with each operating system's code signing process, please read the
+[Code Signing][code-signing] docs.
+
+## Publishing
+
+Once your app is packaged and signed, you can freely distribute your app directly
+to users by uploading your installers online.
+
+To reach more users, you can also choose to upload your app to each operating system's
+digital distribution platform (i.e. app store). These require another build step aside
+from your direct download app. For more information, check out each individual app store guide:
+
+- [Mac App Store][mac-app]
+- [Windows Store][windows-store]
+- [Snapcraft (Linux)][snapcraft]
+
+## Updating
+
+Electron's auto-updater allows you to deliver application updates to users
+without forcing them to manually download new versions of your application.
+Check out the [Updating Applications][updates] guide for details on implementing automatic updates
+with Electron.

+In this section, we have collected a set of guides for common features
+that you may want to implement in your Electron application. Each guide
+contains a practical example in a minimal, self-contained example app.
+The easiest way to run these examples is by downloading [Electron Fiddle][fiddle].
+
+Once Fiddle is installed, you can press on the "Open in Fiddle" button that you
+will find below code samples like the following one:
+
+```fiddle docs/fiddles/quick-start

+  const replaceText = (selector, text) => {
+    const element = document.getElementById(selector)

+  }
+
+  for (const type of ['chrome', 'node', 'electron']) {
+    replaceText(`${type}-version`, process.versions[type])
+  }
+})
+```

 ## Example use cases
 
+### Setting up a MessageChannel between two renderers
+
+In this example, the main process sets up a MessageChannel, then sends each port
+to a different renderer. This allows renderers to send messages to each other
+without needing to use the main process as an in-between.
+
+```js title='main.js (Main Process)'
+const { BrowserWindow, app, MessageChannelMain } = require('electron')
+
+app.whenReady().then(async () => {
+  // create the windows.
+  const mainWindow = new BrowserWindow({
+    show: false,
+    webPreferences: {
+      contextIsolation: false,
+      preload: 'preloadMain.js'
+    }
+  })
+
+  const secondaryWindow = BrowserWindow({
+    show: false,
+    webPreferences: {
+      contextIsolation: false,
+      preload: 'preloadSecondary.js'
+    }
+  })
+
+  // set up the channel.
+  const { port1, port2 } = new MessageChannelMain()
+
+  // once the webContents are ready, send a port to each webContents with postMessage.
+  mainWindow.once('ready-to-show', () => {
+    mainWindow.webContents.postMessage('port', null, [port1])
+  })
+
+  secondaryWindow.once('ready-to-show', () => {
+    secondaryWindow.webContents.postMessage('port', null, [port2])
+  })
+})
+```
+
+Then, in your preload scripts you receive the port through IPC and set up the
+listeners.
+
+```js title='preloadMain.js and preloadSecondary.js (Preload scripts)'
+const { ipcRenderer } = require('electron')
+
+ipcRenderer.on('port', e => {
+  // port received, make it globally available.
+  window.electronMessagePort = e.ports[0]
+
+  window.electronMessagePort.onmessage = messageEvent => {
+    // handle message
+  }
+})
+```
+
+In this example messagePort is bound to the `window` object directly. It is better
+to use `contextIsolation` and set up specific contextBridge calls for each of your
+expected messages, but for the simplicity of this example we don't. You can find an
+example of context isolation further down this page at [Communicating directly between the main process and the main world of a context-isolated page](#communicating-directly-between-the-main-process-and-the-main-world-of-a-context-isolated-page)
+
+That means window.messagePort is globally available and you can call
+`postMessage` on it from anywhere in your app to send a message to the other
+renderer.

+```js title='renderer.js (Renderer Process)'
+// elsewhere in your code to send a message to the other renderers message handler

+
+:::
+
+Electron is a framework for building desktop applications using JavaScript,
+HTML, and CSS. By embedding [Chromium][chromium] and [Node.js][node] into a
+single binary file, Electron allows you to create cross-platform apps that
+work on Windows, macOS, and Linux with a single JavaScript codebase.
+
+This tutorial will guide you through the process of developing a desktop
+application with Electron and distributing it to end users.
+
+## Assumptions
+
+Electron is a native wrapper layer for web apps and is run in a Node.js environment.
+Therefore, this tutorial assumes you are generally familiar with Node and
+front-end web development basics. If you need to do some background reading before
+continuing, we recommend the following resources:
+
+- [Getting started with the Web (MDN Web Docs)][mdn-guide]
+- [Introduction to Node.js][node-guide]
+
+## Required tools
+
+### Code editor
+
+You will need a text editor to write your code. We recommend using [Visual Studio Code],
+although you can choose whichever one you prefer.
+
+### Command line
+
+Throughout the tutorial, we will ask you to use various command-line interfaces (CLIs). You can
+type these commands into your system's default terminal:
+
+- Windows: Command Prompt or PowerShell
+- macOS: Terminal
+- Linux: varies depending on distribution (e.g. GNOME Terminal, Konsole)
+
+Most code editors also come with an integrated terminal, which you can also use.
+
+### Git and GitHub
+
+Git is a commonly-used version control system for source code, and GitHub is a collaborative
+development platform built on top of it. Although neither is strictly necessary to building
+an Electron application, we will use GitHub releases to set up automatic updates later
+on in the tutorial. Therefore, we'll require you to:
+
+- [Create a GitHub account](https://github.com/join)
+- [Install Git](https://github.com/git-guides/install-git)
+
+If you're unfamiliar with how Git works, we recommend reading GitHub's [Git guides]. You can also
+use the [GitHub Desktop] app if you prefer using a visual interface over the command line.
+
+We recommend that you create a local Git repository and publish it to GitHub before starting
+the tutorial, and commit your code after every step.
+
+:::info Installing Git via GitHub Desktop
+
+GitHub Desktop will install the latest version of Git on your system if you don't already have
+it installed.
+
+:::
+
+### Node.js and npm
+
+To begin developing an Electron app, you need to install the [Node.js][node-download]
+runtime and its bundled npm package manager onto your system. We recommend that you
+use the latest long-term support (LTS) version.
+
+:::tip
+
+Please install Node.js using pre-built installers for your platform.
+You may encounter incompatibility issues with different development tools otherwise.
+If you are using macOS, we recommend using a package manager like [Homebrew] or
+[nvm] to avoid any directory permission issues.
+
+:::
+
+To check that Node.js was installed correctly, you can use the `-v` flag when
+running the `node` and `npm` commands. These should print out the installed
+versions.
+
+```sh
+$ node -v
+v16.14.2
+$ npm -v
+8.7.0
+```
+
+:::caution
+
+Although you need Node.js installed locally to scaffold an Electron project,
+Electron **does not use your system's Node.js installation to run its code**. Instead, it
+comes bundled with its own Node.js runtime. This means that your end users do not
+need to install Node.js themselves as a prerequisite to running your app.
+
+To check which version of Node.js is running in your app, you can access the global
+[`process.versions`] variable in the main process or preload script. You can also reference
+the list of versions in the [electron/releases] repository.

+
+## Learning goals
+
+In this part of the tutorial, you will learn how to set up your Electron project
+and write a minimal starter application. By the end of this section,
+you should be able to run a working Electron app in development mode from
+your terminal.
+
+## Setting up your project
+
+:::caution Avoid WSL
+
+If you are on a Windows machine, please do not use [Windows Subsystem for Linux][wsl] (WSL)
+when following this tutorial as you will run into issues when trying to execute the
+application.
+
+<!--https://www.electronforge.io/guides/developing-with-wsl-->
+
+:::
+
+### Initializing your npm project
+
+Electron apps are scaffolded using npm, with the package.json file
+as an entry point. Start by creating a folder and initializing an npm package
+within it with `npm init`.
+
+```sh npm2yarn
+mkdir my-electron-app && cd my-electron-app
+npm init
+```
+
+This command will prompt you to configure some fields in your package.json.
+There are a few rules to follow for the purposes of this tutorial:
+
+- _entry point_ should be `main.js` (you will be creating that file soon).
+- _author_, _license_, and _description_ can be any value, but will be necessary for
+  [packaging][packaging] later on.
+
+Then, install Electron into your app's **devDependencies**, which is the list of external
+development-only package dependencies not required in production.
+
+:::info Why is Electron a devDependency?
+
+This may seem counter-intuitive since your production code is running Electron APIs.
+However, packaged apps will come bundled with the Electron binary, eliminating the need to specify
+it as a production dependency.
+
+:::
+
+```sh npm2yarn
+npm install electron --save-dev
+```
+
+Your package.json file should look something like this after initializing your package
+and installing Electron. You should also now have a `node_modules` folder containing
+the Electron executable, as well as a `package-lock.json` lockfile that specifies
+the exact dependency versions to install.
+
+```json title='package.json'
+{
+  "name": "my-electron-app",
+  "version": "1.0.0",
+  "description": "Hello World!",
+  "main": "main.js",
+  "author": "Jane Doe",
+  "license": "MIT",
+  "devDependencies": {
+    "electron": "19.0.0"
+  }
+}
+```
+
+:::info Advanced Electron installation steps
+
+If installing Electron directly fails, please refer to our [Advanced Installation][installation]
+documentation for instructions on download mirrors, proxies, and troubleshooting steps.
+
+:::
+
+### Adding a .gitignore
+
+The [`.gitignore`][gitignore] file specifies which files and directories to avoid tracking
+with Git. You should place a copy of [GitHub's Node.js gitignore template][gitignore-template]
+into your project's root folder to avoid committing your project's `node_modules` folder.
+
+## Running an Electron app
+
+:::tip Further reading
+
+Read [Electron's process model][process-model] documentation to better
+understand how Electron's multiple processes work together.
+
+:::
+
+The [`main`][package-json-main] script you defined in package.json is the entry point of any
+Electron application. This script controls the **main process**, which runs in a Node.js
+environment and is responsible for controlling your app's lifecycle, displaying native
+interfaces, performing privileged operations, and managing renderer processes
+(more on that later).
+
+Before creating your first Electron app, you will first use a trivial script to ensure your
+main process entry point is configured correctly. Create a `main.js` file in the root folder
+of your project with a single line of code:
+
+```js title='main.js'
+console.log(`Hello from Electron 👋`)
+```
+
+Because Electron's main process is a Node.js runtime, you can execute arbitrary Node.js code
+with the `electron` command (you can even use it as a [REPL]). To execute this script,
+add `electron .` to the `start` command in the [`scripts`][package-scripts]
+field of your package.json. This command will tell the Electron executable to look for the main
+script in the current directory and run it in dev mode.
+
+```json {8-10} title='package.json'
+{
+  "name": "my-electron-app",
+  "version": "1.0.0",
+  "description": "Hello World!",
+  "main": "main.js",
+  "author": "Jane Doe",
+  "license": "MIT",
+  "scripts": {
+    "start": "electron ."
+  },
+  "devDependencies": {
+    "electron": "^19.0.0"
+  }
+}
+```
+
+```sh npm2yarn
+npm run start
+```
+
+Your terminal should print out `Hello from Electron 👋`. Congratulations,
+you have executed your first line of code in Electron! Next, you will learn
+how to create user interfaces with HTML and load that into a native window.
+
+## Loading a web page into a BrowserWindow
+
+In Electron, each window displays a web page that can be loaded either from a local HTML
+file or a remote web address. For this example, you will be loading in a local file. Start
+by creating a barebones web page in an `index.html` file in the root folder of your project:
+
+```html title='index.html'
+<!DOCTYPE html>
+<html>
+  <head>
+    <meta charset="UTF-8" />
+    <!-- https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP -->
+    <meta
+      http-equiv="Content-Security-Policy"
+      content="default-src 'self'; script-src 'self'"
+    />
+    <meta
+      http-equiv="X-Content-Security-Policy"
+      content="default-src 'self'; script-src 'self'"
+    />
+    <title>Hello from Electron renderer!</title>
+  </head>
+  <body>
+    <h1>Hello from Electron renderer!</h1>
+    <p>👋</p>
+  </body>
+</html>
+```
+
+Now that you have a web page, you can load it into an Electron [BrowserWindow][browser-window].
+Replace the contents your `main.js` file with the following code. We will explain each
+highlighted block separately.
+
+```js {1,3-10,12-14} title='main.js' showLineNumbers
+const { app, BrowserWindow } = require('electron')
+
+const createWindow = () => {
+  const win = new BrowserWindow({
+    width: 800,
+    height: 600,
+  })
+
+  win.loadFile('index.html')
+}
+
+app.whenReady().then(() => {
+  createWindow()
+})
+```
+
+### Importing modules
+
+```js title='main.js (Line 1)'
+const { app, BrowserWindow } = require('electron')
+```
+
+In the first line, we are importing two Electron modules
+with CommonJS module syntax:
+
+- [app][app], which controls your application's event lifecycle.
+- [BrowserWindow][browser-window], which creates and manages app windows.
+
+:::info Capitalization conventions
+
+You might have noticed the capitalization difference between the **a**pp
+and **B**rowser**W**indow modules. Electron follows typical JavaScript conventions here,
+where PascalCase modules are instantiable class constructors (e.g. BrowserWindow, Tray,
+Notification) whereas camelCase modules are not instantiable (e.g. app, ipcRenderer, webContents).
+
+:::
+
+:::warning ES Modules in Electron
+
+[ECMAScript modules](https://nodejs.org/api/esm.html) (i.e. using `import` to load a module)
+are currently not directly supported in Electron. You can find more information about the
+state of ESM in Electron in [electron/electron#21457](https://github.com/electron/electron/issues/21457).
+
+:::
+
+### Writing a reusable function to instantiate windows
+
+The `createWindow()` function loads your web page into a new BrowserWindow instance:
+
+```js title='main.js (Lines 3-10)'
+const createWindow = () => {
+  const win = new BrowserWindow({
+    width: 800,
+    height: 600,
+  })
+
+  win.loadFile('index.html')
+}
+```
+
+### Calling your function when the app is ready
+
+```js title='main.js (Lines 12-14)'
+app.whenReady().then(() => {
+  createWindow()
+})
+```
+
+Many of Electron's core modules are Node.js [event emitters] that adhere to Node's asynchronous
+event-driven architecture. The app module is one of these emitters.
+
+In Electron, BrowserWindows can only be created after the app module's [`ready`][app-ready] event
+is fired. You can wait for this event by using the [`app.whenReady()`][app-when-ready] API and
+calling `createWindow()` once its promise is fulfilled.
+
+:::info
+
+You typically listen to Node.js events by using an emitter's `.on` function.
+
+```diff
++ app.on('ready').then(() => {
+- app.whenReady().then(() => {
+  createWindow()
+})
+```
+
+However, Electron exposes `app.whenReady()` as a helper specifically for the `ready` event to
+avoid subtle pitfalls with directly listening to that event in particular.
+See [electron/electron#21972](https://github.com/electron/electron/pull/21972) for details.
+
+:::
+
+At this point, running your Electron application's `start` command should successfully
+open a window that displays your web page!
+
+Each web page your app displays in a window will run in a separate process called a
+**renderer** process (or simply _renderer_ for short). Renderer processes have access
+to the same JavaScript APIs and tooling you use for typical front-end web
+development, such as using [webpack] to bundle and minify your code or [React][react]
+to build your user interfaces.
+
+## Managing your app's window lifecycle
+
+Application windows behave differently on each operating system. Rather than
+enforce these conventions by default, Electron gives you the choice to implement
+them in your app code if you wish to follow them. You can implement basic window
+conventions by listening for events emitted by the app and BrowserWindow modules.
+
+:::tip Process-specific control flow
+
+Checking against Node's [`process.platform`][node-platform] variable can help you
+to run code conditionally on certain platforms. Note that there are only three
+possible platforms that Electron can run in: `win32` (Windows), `linux` (Linux),
+and `darwin` (macOS).
+
+:::
+
+### Quit the app when all windows are closed (Windows & Linux)
+
+On Windows and Linux, closing all windows will generally quit an application entirely.
+To implement this pattern in your Electron app, listen for the app module's
+[`window-all-closed`][window-all-closed] event, and call [`app.quit()`][app-quit]
+to exit your app if the user is not on macOS.
+
+```js
+app.on('window-all-closed', () => {
+  if (process.platform !== 'darwin') app.quit()
+})
+```
+
+### Open a window if none are open (macOS)
+
+In contrast, macOS apps generally continue running even without any windows open.
+Activating the app when no windows are available should open a new one.
+
+To implement this feature, listen for the app module's [`activate`][activate]
+event, and call your existing `createWindow()` method if no BrowserWindows are open.
+
+Because windows cannot be created before the `ready` event, you should only listen for
+`activate` events after your app is initialized. Do this by only listening for activate
+events inside your existing `whenReady()` callback.
+
+```js
+app.whenReady().then(() => {
+  createWindow()
+
+  app.on('activate', () => {
+    if (BrowserWindow.getAllWindows().length === 0) createWindow()
+  })
+})
+```
+
+## Final starter code
+
+```fiddle docs/fiddles/tutorial-first-app
+
+```
+
+## Optional: Debugging from VS Code
+
+If you want to debug your application using VS Code, you have need attach VS Code to
+both the main and renderer processes. Here is a sample configuration for you to
+run. Create a launch.json configuration in a new `.vscode` folder in your project:
+
+```json title='.vscode/launch.json'
+{
+  "version": "0.2.0",
+  "compounds": [
+    {
+      "name": "Main + renderer",
+      "configurations": ["Main", "Renderer"],
+      "stopAll": true
+    }
+  ],
+  "configurations": [
+    {
+      "name": "Renderer",
+      "port": 9222,
+      "request": "attach",
+      "type": "pwa-chrome",
+      "webRoot": "${workspaceFolder}"
+    },
+    {
+      "name": "Main",
+      "type": "pwa-node",
+      "request": "launch",
+      "cwd": "${workspaceFolder}",
+      "runtimeExecutable": "${workspaceFolder}/node_modules/.bin/electron",
+      "windows": {
+        "runtimeExecutable": "${workspaceFolder}/node_modules/.bin/electron.cmd"
+      },
+      "args": [".", "--remote-debugging-port=9222"],
+      "outputCapture": "std",
+      "console": "integratedTerminal"
+    }
+  ]
+}
+```
+
+The "Main + renderer" option will appear when you select "Run and Debug"
+from the sidebar, allowing you to set breakpoints and inspect all the variables among
+other things in both the main and renderer processes.
+
+What we have done in the `launch.json` file is to create 3 configurations:
+
+- `Main` is used to start the main process and also expose port 9222 for remote debugging
+  (`--remote-debugging-port=9222`). This is the port that we will use to attach the debugger
+  for the `Renderer`. Because the main process is a Node.js process, the type is set to
+  `pwa-node` (`pwa-` is the prefix that tells VS Code to use the latest JavaScript debugger).
+- `Renderer` is used to debug the renderer process. Because the main process is the one
+  that creates the process, we have to "attach" to it (`"request": "attach"`) instead of
+  creating a new one.
+  The renderer process is a web one, so the debugger we have to use is `pwa-chrome`.
+- `Main + renderer` is a [compound task] that executes the previous ones simultaneously.
+
+:::caution
+
+Because we are attaching to a process in `Renderer`, it is possible that the first lines of
+your code will be skipped as the debugger will not have had enough time to connect before they are
+being executed.
+You can work around this by refreshing the page or setting a timeout before executing the code
+in development mode.
+
+:::
+
+:::info Further reading
+
+If you want to dig deeper in the debugging area, the following guides provide more information:

+
+## Summary
+
+Electron applications are set up using npm packages. The Electron executable should be installed
+in your project's `devDependencies` and can be run in development mode using a script in your
+package.json file.
+
+The executable runs the JavaScript entry point found in the `main` property of your package.json.
+This file controls Electron's **main process**, which runs an instance of Node.js and is
+responsible for your app's lifecycle, displaying native interfaces, performing privileged operations,
+and managing renderer processes.
+
+**Renderer processes** (or renderers for short) are responsible for display graphical content. You can
+load a web page into a renderer by pointing it to either a web address or a local HTML file.
+Renderers behave very similarly to regular web pages and have access to the same web APIs.
+
+In the next section of the tutorial, we will be learning how to augment the renderer process with
+privileged APIs and how to communicate between processes.

+1. **[Using Preload Scripts][preload]**
+1. [Adding Features][features]

+1. [Publishing and Updating][updates]
+
+:::
+
+## Learning goals
+
+In this part of the tutorial, you will learn what a preload script is and how to use one
+to securely expose privileged APIs into the renderer process. You will also learn how to
+communicate between main and renderer processes with Electron's inter-process
+communication (IPC) modules.
+
+## What is a preload script?
+
+Electron's main process is a Node.js environment that has full operating system access.
+On top of [Electron modules][modules], you can also access [Node.js built-ins][node-api],
+as well as any packages installed via npm. On the other hand, renderer processes run web
+pages and do not run Node.js by default for security reasons.
+
+To bridge Electron's different process types together, we will need to use a special script
+called a **preload**.
+
+## Augmenting the renderer with a preload script
+
+A BrowserWindow's preload script runs in a context that has access to both the HTML DOM
+and a Node.js environment. Preload scripts are injected before a web page loads in the renderer,
+similar to a Chrome extension's [content scripts][content-script]. To add features to your renderer
+that require privileged access, you can define [global] objects through the
+[contextBridge][contextbridge] API.
+
+To demonstrate this concept, you will create a preload script that exposes your app's
+versions of Chrome, Node, and Electron into the renderer.
+
+Add a new `preload.js` script that exposes selected properties of Electron's `process.versions`
+object to the renderer process in a `versions` global variable.
+
+```js title="preload.js"
+const { contextBridge } = require('electron')
+
+contextBridge.exposeInMainWorld('versions', {
+  node: () => process.versions.node,
+  chrome: () => process.versions.chrome,
+  electron: () => process.versions.electron,
+  // we can also expose variables, not just functions
+})
+```
+
+To attach this script to your renderer process, pass its path to the
+`webPreferences.preload` option in the BrowserWindow constructor:
+
+```js {8-10} title="main.js"
+const { app, BrowserWindow } = require('electron')
+const path = require('path')
+
+const createWindow = () => {
+  const win = new BrowserWindow({
+    width: 800,
+    height: 600,
+    webPreferences: {
+      preload: path.join(__dirname, 'preload.js'),
+    },
+  })
+
+  win.loadFile('index.html')
+}
+
+app.whenReady().then(() => {
+  createWindow()
+})
+```
+
+:::info
+
+There are two Node.js concepts that are used here:
+
+- The [`__dirname`][dirname] string points to the path of the currently executing script
+  (in this case, your project's root folder).
+- The [`path.join`][path-join] API joins multiple path segments together, creating a
+  combined path string that works across all platforms.
+
+:::
+
+At this point, the renderer has access to the `versions` global, so let's display that
+information in the window. This variable can be accessed via `window.versions` or simply
+`versions`. Create a `renderer.js` script that uses the [`document.getElementById`]
+DOM API to replace the displayed text for the HTML element with `info` as its `id` property.
+
+```js title="renderer.js"
+const information = document.getElementById('info')
+information.innerText = `This app is using Chrome (v${versions.chrome()}), Node.js (v${versions.node()}), and Electron (v${versions.electron()})`
+```
+
+Then, modify your `index.html` by adding a new element with `info` as its `id` property,
+and attach your `renderer.js` script:
+
+```html {18,20} title="index.html"
+<!DOCTYPE html>
+<html>
+  <head>
+    <meta charset="UTF-8" />
+    <meta
+      http-equiv="Content-Security-Policy"
+      content="default-src 'self'; script-src 'self'"
+    />
+    <meta
+      http-equiv="X-Content-Security-Policy"
+      content="default-src 'self'; script-src 'self'"
+    />
+    <title>Hello from Electron renderer!</title>
+  </head>
+  <body>
+    <h1>Hello from Electron renderer!</h1>
+    <p>👋</p>
+    <p id="info"></p>
+  </body>
+  <script src="./renderer.js"></script>
+</html>
+```
+
+After following the above steps, your app should look something like this:
+
+![Electron app showing This app is using Chrome (v102.0.5005.63), Node.js (v16.14.2), and Electron (v19.0.3)](../images/preload-example.png)
+
+And the code should look like this:
+
+```fiddle docs/fiddles/tutorial-preload
+
+```
+
+## Communicating between processes
+
+As we have mentioned above, Electron's main and renderer process have distinct responsibilities
+and are not interchangeable. This means it is not possible to access the Node.js APIs directly
+from the renderer process, nor the HTML Document Object Model (DOM) from the main process.
+
+The solution for this problem is to use Electron's `ipcMain` and `ipcRenderer` modules for
+inter-process communication (IPC). To send a message from your web page to the main process,
+you can set up a main process handler with `ipcMain.handle` and
+then expose a function that calls `ipcRenderer.invoke` to trigger the handler in your preload script.
+
+To illustrate, we will add a global function to the renderer called `ping()`
+that will return a string from the main process.
+
+First, set up the `invoke` call in your preload script:
+
+```js {1,7} title="preload.js"
+const { contextBridge, ipcRenderer } = require('electron')
+
+contextBridge.exposeInMainWorld('versions', {
+  node: () => process.versions.node,
+  chrome: () => process.versions.chrome,
+  electron: () => process.versions.electron,
+  ping: () => ipcRenderer.invoke('ping'),
+  // we can also expose variables, not just functions
+})
+```
+
+:::caution IPC security
+
+Notice how we wrap the `ipcRenderer.invoke('ping')` call in a helper function rather
+than expose the `ipcRenderer` module directly via context bridge. You **never** want to
+directly expose the entire `ipcRenderer` module via preload. This would give your renderer
+the ability to send arbitrary IPC messages to the main process, which becomes a powerful
+attack vector for malicious code.
+
+:::
+
+Then, set up your `handle` listener in the main process. We do this _before_
+loading the HTML file so that the handler is guaranteed to be ready before
+you send out the `invoke` call from the renderer.
+
+```js {1,11} title="main.js"
+const { ipcMain } = require('electron')
+
+const createWindow = () => {
+  const win = new BrowserWindow({
+    width: 800,
+    height: 600,
+    webPreferences: {
+      preload: path.join(__dirname, 'preload.js'),
+    },
+  })
+  ipcMain.handle('ping', () => 'pong')
+  win.loadFile('index.html')
+}
+```
+
+Once you have the sender and receiver set up, you can now send messages from the renderer
+to the main process through the `'ping'` channel you just defined.
+
+```js title='renderer.js'
+const func = async () => {
+  const response = await window.versions.ping()
+  console.log(response) // prints out 'pong'
+}
+
+func()
+```
+
+:::info
+
+For more in-depth explanations on using the `ipcRenderer` and `ipcMain` modules,
+check out the full [Inter-Process Communication][ipc] guide.
+
+:::
+
+## Summary
+
+A preload script contains code that runs before your web page is loaded into the browser
+window. It has access to both DOM APIs and Node.js environment, and is often used to
+expose privileged APIs to the renderer via the `contextBridge` API.
+
+Because the main and renderer processes have very different responsibilities, Electron
+apps often use the preload script to set up inter-process communication (IPC) interfaces
+to pass arbitrary messages between the two kinds of processes.
+
+In the next part of the tutorial, we will be showing you resources on adding more
+functionality to your app, then teaching you distributing your app to users.

+## Adding application complexity
+
+If you have been following along, you should have a functional Electron application
+with a static user interface. From this starting point, you can generally progress
+in developing your app in two broad directions:
+
+1. Adding complexity to your renderer process' web app code
+1. Deeper integrations with the operating system and Node.js
+
+It is important to understand the distinction between these two broad concepts. For the
+first point, Electron-specific resources are not necessary. Building a pretty to-do
+list in Electron is just pointing your Electron BrowserWindow to a pretty
+to-do list web app. Ultimately, you are building your renderer's UI using the same tools
+(HTML, CSS, JavaScript) that you would on the web. Therefore, Electron's docs will
+not go in-depth on how to use standard web tools.
+
+On the other hand, Electron also provides a rich set of tools that allow
+you to integrate with the desktop environment, from creating tray icons to adding
+global shortcuts to displaying native menus. It also gives you all the power of a
+Node.js environment in the main process. This set of capabilities separates
+Electron applications from running a website in a browser tab, and are the
+focus of Electron's documentation.
+
+## How-to examples
+
+Electron's documentation has many tutorials to help you with more advanced topics
+and deeper operating system integrations. To get started, check out the
+[How-To Examples][how-to] doc.

+
+## Learning goals
+
+In this part of the tutorial, we'll be going over the basics of packaging and distributing
+your app with [Electron Forge].
+
+## Using Electron Forge
+
+Electron does not have any tooling for packaging and distribution bundled into its core
+modules. Once you have a working Electron app in dev mode, you need to use
+additional tooling to create a packaged app you can distribute to your users (also known
+as a **distributable**). Distributables can be either installers (e.g. MSI on Windows) or
+portable executable files (e.g. `.app` on macOS).
+
+Electron Forge is an all-in-one tool that handles the packaging and distribution of Electron
+apps. Under the hood, it combines a lot of existing Electron tools (e.g. [`electron-packager`],
+[`@electron/osx-sign`], [`electron-winstaller`], etc.) into a single interface so you do not
+have to worry about wiring them all together.
+
+### Importing your project into Forge
+
+You can install Electron Forge's CLI in your project's `devDependencies` and import your
+existing project with a handy conversion script.
+
+```sh npm2yarn
+npm install --save-dev @electron-forge/cli
+npx electron-forge import
+```
+
+Once the conversion script is done, Forge should have added a few scripts
+to your `package.json` file.
+
+```json title='package.json'
+  //...
+  "scripts": {
+    "start": "electron-forge start",
+    "package": "electron-forge package",
+    "make": "electron-forge make"
+  },
+  //...
+```
+
+:::info CLI documentation
+
+For more information on `make` and other Forge APIs, check out
+the [Electron Forge CLI documentation].
+
+:::
+
+You should also notice that your package.json now has a few more packages installed
+under your `devDependencies`, and contains an added `config.forge` field with an array
+of makers configured. **Makers** are Forge plugins that create distributables from
+your source code. You should see multiple makers in the pre-populated configuration,
+one for each target platform.
+
+### Creating a distributable
+
+To create a distributable, use your project's new `make` script, which runs the
+`electron-forge make` command.
+
+```sh npm2yarn
+npm run make
+```
+
+This `make` command contains two steps:
+
+1. It will first run `electron-forge package` under the hood, which bundles your app
+   code together with the Electron binary. The packaged code is generated into a folder.
+1. It will then use this packaged app folder to create a separate distributable for each
+   configured maker.
+
+After the script runs, you should see an `out` folder containing both the distributable
+and a folder containing the packaged application code.
+
+```plain title='macOS output example'
+out/
+├── out/make/zip/darwin/x64/my-electron-app-darwin-x64-1.0.0.zip
+├── ...
+└── out/my-electron-app-darwin-x64/my-electron-app.app/Contents/MacOS/my-electron-app
+```
+
+The distributable in the `out/make` folder should be ready to launch! You have now
+created your first bundled Electron application.
+
+:::tip Distributable formats
+
+Electron Forge can be configured to create distributables in different OS-specific formats
+(e.g. DMG, deb, MSI, etc.). See Forge's [Makers] documentation for all configuration options.
+
+:::
+
+:::note Packaging without Electron Forge
+
+If you want to manually package your code, or if you're just interested understanding the
+mechanics behind packaging an Electron app, check out the full [Application Packaging]
+documentation.
+
+:::
+
+## Important: signing your code
+
+In order to distribute desktop applications to end users, we _highly recommended_ for you
+to **code sign** your Electron app. Code signing is an important part of shipping
+desktop applications, and is mandatory for the auto-update step in the final part
+of the tutorial.
+
+Code signing is a security technology that you use to certify that a desktop app was
+created by a known source. Windows and macOS have their own OS-specific code signing
+systems that will make it difficult for users to download or launch unsigned applications.
+
+If you already have code signing certificates for Windows and macOS, you can set your
+credentials in your Forge configuration. Otherwise, please refer to the full
+[Code Signing] documentation to learn how to purchase a certificate and for more information
+on the desktop app code signing process.
+
+On macOS, code signing is done at the app packaging level. On Windows, distributable installers
+are signed instead.

+
+## Summary
+
+Electron applications need to be packaged to be distributed to users. In this tutorial,
+you imported your app into Electron Forge and configured it to package your app and
+generate installers.
+
+In order for your application to be trusted by the user's system, you need to digitally
+certify that the distributable is authentic and untampered by code signing it. Your app
+can be signed through Forge once you configure it to use your code signing certificate
+information.

+## Learning goals
+
+If you've been following along, this is the last step of the tutorial! In this part,
+you will publish your app to GitHub releases and integrate automatic updates
+into your app code.
+
+## Using update.electronjs.org
+
+The Electron maintainers provide a free auto-updating service for open-source apps
+at https://update.electronjs.org. Its requirements are:
+
+- Your app runs on macOS or Windows
+- Your app has a public GitHub repository
+- Builds are published to [GitHub releases]
+- Builds are [code signed][code-signed]
+
+At this point, we'll assume that you have already pushed all your
+code to a public GitHub repository.
+
+:::info Alternative update services
+
+If you're using an alternate repository host (e.g. GitLab or Bitbucket) or if
+you need to keep your code repository private, please refer to our
+[step-by-step guide][update-server] on hosting your own Electron update server.
+
+:::
+
+## Publishing a GitHub release
+
+Electron Forge has [Publisher] plugins that can automate the distribution
+of your packaged application to various sources. In this tutorial, we will
+be using the GitHub Publisher, which will allow us to publish
+our code to GitHub releases.
+
+### Generating a personal access token
+
+Forge cannot publish to any repository on GitHub without permission. You
+need to pass in an authenticated token that gives Forge access to
+your GitHub releases. The easiest way to do this is to
+[create a new personal access token (PAT)][new-pat]
+with the `public_repo` scope, which gives write access to your public repositories.
+**Make sure to keep this token a secret.**
+
+### Setting up the GitHub Publisher
+
+#### Installing the module
+
+Forge's [GitHub Publisher] is a plugin that
+needs to be installed in your project's `devDependencies`:
+
+```sh npm2yarn
+npm install --save-dev @electron-forge/publisher-github
+```
+
+#### Configuring the publisher in Forge
+
+Once you have it installed, you need to set it up in your Forge
+configuration. A full list of options is documented in the Forge's
+[`PublisherGitHubConfig`] API docs.
+
+```json title='package.json' {6-16}
+{
+  //...

+
+:::tip Drafting releases before publishing
+
+Notice that you have configured Forge to publish your release as a draft.
+This will allow you to see the release with its generated artifacts
+without actually publishing it to your end users. You can manually
+publish your releases via GitHub after writing release notes and
+double-checking that your distributables work.
+
+:::
+
+#### Setting up your authentication token
+
+You also need to make the Publisher aware of your authentication token.
+By default, it will use the value stored in the `GITHUB_TOKEN` environment
+variable.
+
+### Running the publish command
+
+Add Forge's [publish command] to your npm scripts.
+
+```json {6} title='package.json'
+  //...
+  "scripts": {
+    "start": "electron-forge start",
+    "package": "electron-forge package",
+    "make": "electron-forge make",
+    "publish": "electron-forge publish"
+  },
+  //...
+```
+
+This command will run your configured makers and publish the output distributables to a new
+GitHub release.
+
+```sh npm2yarn
+npm run publish
+```
+
+By default, this will only publish a single distributable for your host operating system and
+architecture. You can publish for different architectures by passing in the `--arch` flag to your
+Forge commands.
+
+The name of this release will correspond to the `version` field in your project's package.json file.
+
+:::tip Tagging releases
+
+Optionally, you can also [tag your releases in Git][git-tag] so that your
+release is associated with a labeled point in your code history. npm comes
+with a handy [`npm version`](https://docs.npmjs.com/cli/v8/commands/npm-version)
+command that can handle the version bumping and tagging for you.
+
+:::
+
+#### Bonus: Publishing in GitHub Actions
+
+Publishing locally can be painful, especially because you can only create distributables
+for your host operating system (i.e. you can't publish a Window `.exe` file from macOS).
+
+A solution for this would be to publish your app via automation workflows
+such as [GitHub Actions], which can run tasks in the
+cloud on Ubuntu, macOS, and Windows. This is the exact approach taken by [Electron Fiddle].
+You can refer to Fiddle's [Build and Release pipeline][fiddle-build]
+and [Forge configuration][fiddle-forge-config]
+for more details.
+
+## Instrumenting your updater code
+
+Now that we have a functional release system via GitHub releases, we now need to tell our
+Electron app to download an update whenever a new release is out. Electron apps do this
+via the [autoUpdater] module, which reads from an update server feed to check if a new version
+is available for download.
+
+The update.electronjs.org service provides an updater-compatible feed. For example, Electron
+Fiddle v0.28.0 will check the endpoint at https://update.electronjs.org/electron/fiddle/darwin/v0.28.0
+to see if a newer GitHub release is available.
+
+After your release is published to GitHub, the update.electronjs.org service should work
+for your application. The only step left is to configure the feed with the autoUpdater module.
+
+To make this process easier, the Electron team maintains the [`update-electron-app`] module,
+which sets up the autoUpdater boilerplate for update.electronjs.org in one function
+call — no configuration required. This module will search for the update.electronjs.org
+feed that matches your project's package.json `"repository"` field.
+
+First, install the module as a runtime dependency.
+
+```sh npm2yarn
+npm install update-electron-app
+```
+
+Then, import the module and call it immediately in the main process.
+
+```js title='main.js'
+require('update-electron-app')()
+```
+
+And that is all it takes! Once your application is packaged, it will update itself for each new
+GitHub release that you publish.
+
+## Summary
+
+In this tutorial, we configured Electron Forge's GitHub Publisher to upload your app's
+distributables to GitHub releases. Since distributables cannot always be generated
+between platforms, we recommend setting up your building and publishing flow
+in a Continuous Integration pipeline if you do not have access to machines.
+
+Electron applications can self-update by pointing the autoUpdater module to an update server feed.
+update.electronjs.org is a free update server provided by Electron for open-source applications
+published on GitHub releases. Configuring your Electron app to use this service is as easy as
+installing and importing the `update-electron-app` module.
+
+If your application is not eligible for update.electronjs.org, you should instead deploy your
+own update server and configure the autoUpdater module yourself.
