-:::caution Keep your certificate password private
-Your certificate password should be a **secret**. Do not share it publicly or
-commit it to your source code.
-:::
+There are a number of tools for signing your packaged app:
 
-### Using Electron Forge
+* [`electron-winstaller`] will generate an installer for windows and sign it for
+  you
+* [`electron-forge`] can sign installers it generates through the
+  Squirrel.Windows or MSI targets.
+* [`electron-builder`] can sign some of its windows targets

-[Squirrel.Windows][maker-squirrel] and [MSI][maker-msi] installers in Electron Forge
-with the `certificateFile` and `certificatePassword` fields in their respective
-configuration objects.
-
-For example, if you keep your Forge config in your `package.json` file and are
-creating a Squirrel.Windows installer:
-
-```json {9-15} title='package.json'
-{
-  "name": "my-app",

-
-[`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

-options when creating your installer.

-`certificateFile` and `certificatePassword` configuration options
-or pass in parameters directly to [SignTool.exe] with the `signWithParams` option.

-Once your app is ready for production, there are a couple steps you need to take before

-## 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.

-We recommend you to start with the [tutorial], which guides you through the
-process of developing an Electron app and distributing it to users.
-The [examples] and [API documentation] are also good places to browse around
-and discover new things.
+These docs operate under the assumption that the reader is familiar with both

+either of these areas, we recommend the following resources:
+
+* [Getting started with the Web (MDN)][mdn-guide]
+* [Introduction to Node.js][node-guide]
+
+Moreover, you'll have a better time understanding how Electron works if you get
+acquainted with Chromium's process model. You can get a brief overview of
+Chrome architecture with the [Chrome comic][comic], which was released alongside
+Chrome's launch back in 2008. Although it's been over a decade since then, the

 ## 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
-window.electronMessagePort.postmessage('ping')

-:::
-
-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 need to 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.
-
-:::

-
-## 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.

-:::
-
-## 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

-
-:::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.

-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](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}
-{
-  //...
-  "config": {
-    "forge": {
-      "publishers": [
-        {
-          "name": "@electron-forge/publisher-github",
-          "config": {
-            "repository": {
-              "owner": "github-user-name",
-              "name": "github-repo-name"
-            },
-            "prerelease": false,
-            "draft": true
-          }
-        }
-      ]
-    }
-  }
-  //...
-}
-```
-
-:::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.
