-## Version support policy
-
-:::info
-
-Beginning in September 2021 (Electron 15), the Electron team
-will temporarily support the latest **four** stable major versions. This
-extended support is intended to help Electron developers transition to
-the [new 8-week release cadence](https://electronjs.org/blog/8-week-cadence),
-and will continue until the release of Electron 19. At that time,
-the Electron team will drop support back to the latest three stable major versions.
-
-:::
-
-The latest three *stable* major versions are supported by the Electron team.
-For example, if the latest release is 6.1.x, then the 5.0.x as well
-as the 4.2.x series are supported. We only support the latest minor release
-for each stable release series. This means that in the case of a security fix,
-6.1.x will receive the fix, but we will not release a new version of 6.0.x.
-
-The latest stable release unilaterally receives all fixes from `main`,
-and the version prior to that receives the vast majority of those fixes
-as time and bandwidth warrants. The oldest supported release line will receive
-only security fixes directly.
-
-### Breaking API changes
-
-When an API is changed or removed in a way that breaks existing functionality, the
-previous functionality will be supported for a minimum of two major versions when
-possible before being removed. For example, if a function takes three arguments,
-and that number is reduced to two in major version 10, the three-argument version would
-continue to work until, at minimum, major version 12. Past the minimum two-version
-threshold, we will attempt to support backwards compatibility beyond two versions
-until the maintainers feel the maintenance burden is too high to continue doing so.
-
-### End-of-life
-
-When a release branch reaches the end of its support cycle, the series
-will be deprecated in NPM and a final end-of-support release will be
-made. This release will add a warning to inform that an unsupported
-version of Electron is in use.
-
-These steps are to help app developers learn when a branch they're
-using becomes unsupported, but without being excessively intrusive
-to end users.
-
-If an application has exceptional circumstances and needs to stay
-on an unsupported series of Electron, developers can silence the
-end-of-support warning by omitting the final release from the app's
-`package.json` `devDependencies`. For example, since the 1-6-x series
-ended with an end-of-support 1.6.18 release, developers could choose
-to stay in the 1-6-x series without warnings with `devDependency` of
-`"electron": 1.6.0 - 1.6.17`.

-# Inter-Process Communication
-
-Inter-process communication (IPC) is a key part of building feature-rich desktop applications
-in Electron. Because the main and renderer processes have different responsibilities in
-Electron's process model, IPC is the only way to perform many common tasks, such as calling a
-native API from your UI or triggering changes in your web contents from native menus.
-
-## IPC channels
-
-In Electron, processes communicate by passing messages through developer-defined "channels"
-with the [`ipcMain`] and [`ipcRenderer`] modules. These channels are
-**arbitrary** (you can name them anything you want) and **bidirectional** (you can use the
-same channel name for both modules).
-
-In this guide, we'll be going over some fundamental IPC patterns with concrete examples that
-you can use as a reference for your app code.
-
-## Understanding context-isolated processes
-
-Before proceeding to implementation details, you should be familiar with the idea of using a
-[preload script] to import Node.js and Electron modules in a context-isolated renderer process.
-
-* For a full overview of Electron's process model, you can read the [process model docs].
-* For a primer into exposing APIs from your preload script using the `contextBridge` module, check
-out the [context isolation tutorial].
-
-## Pattern 1: Renderer to main (one-way)
-
-To fire a one-way IPC message from a renderer process to the main process, you can use the
-[`ipcRenderer.send`] API to send a message that is then received by the [`ipcMain.on`] API.
-
-You usually use this pattern to call a main process API from your web contents. We'll demonstrate
-this pattern by creating a simple app that can programmatically change its window title.
-
-For this demo, you'll need to add code to your main process, your renderer process, and a preload
-script. The full code is below, but we'll be explaining each file individually in the following
-sections.
-
-```fiddle docs/fiddles/ipc/pattern-1
-```
-
-### 1. Listen for events with `ipcMain.on`
-
-In the main process, set an IPC listener on the `set-title` channel with the `ipcMain.on` API:
-
-```javascript {6-10,22} title='main.js (Main Process)'
-const {app, BrowserWindow, ipcMain} = require('electron')
-const path = require('path')
-
-//...
-
-function handleSetTitle (event, title) {
-  const webContents = event.sender
-  const win = BrowserWindow.fromWebContents(webContents)
-  win.setTitle(title)
-}
-
-function createWindow () {
-  const mainWindow = new BrowserWindow({
-    webPreferences: {
-      preload: path.join(__dirname, 'preload.js')
-    }
-  })
-  mainWindow.loadFile('index.html')
-}
-
-app.whenReady().then(() => {
-  ipcMain.on('set-title', handleSetTitle)
-  createWindow()
-}
-//...
-```
-
-The above `handleSetTitle` callback has two parameters: an [IpcMainEvent] structure and a
-`title` string. Whenever a message comes through the `set-title` channel, this function will
-find the BrowserWindow instance attached to the message sender and use the `win.setTitle`
-API on it.
-
-:::info
-Make sure you're loading the `index.html` and `preload.js` entry points for the following steps!
-:::
-
-### 2. Expose `ipcRenderer.send` via preload
-
-To send messages to the listener created above, you can use the `ipcRenderer.send` API.
-By default, the renderer process has no Node.js or Electron module access. As an app developer,
-you need to choose which APIs to expose from your preload script using the `contextBridge` API.
-
-In your preload script, add the following code, which will expose a global `window.electronAPI`
-variable to your renderer process.
-
-```javascript title='preload.js (Preload Script)'
-const { contextBridge, ipcRenderer } = require('electron')
-
-contextBridge.exposeInMainWorld('electronAPI', {
-    setTitle: (title) => ipcRenderer.send('set-title', title)
-})
-```
-
-At this point, you'll be able to use the `window.electronAPI.setTitle()` function in the renderer
-process.
-
-:::caution Security warning
-We don't directly expose the whole `ipcRenderer.send` API for [security reasons]. Make sure to
-limit the renderer's access to Electron APIs as much as possible.
-:::
-
-### 3. Build the renderer process UI
-
-In our BrowserWindow's loaded HTML file, add a basic user interface consisting of a text input
-and a button:
-
-```html {11-12} 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'">
-    <title>Hello World!</title>
-  </head>
-  <body>
-    Title: <input id="title"/>
-    <button id="btn" type="button">Set</button>
-    <script src="./renderer.js"></script>
-  </body>
-</html>
-```
-
-To make these elements interactive, we'll be adding a few lines of code in the imported
-`renderer.js` file that leverages the `window.electronAPI` functionality exposed from the preload
-script:
-
-```javascript title='renderer.js (Renderer Process)'
-const setButton = document.getElementById('btn')
-const titleInput = document.getElementById('title')
-setButton.addEventListener('click', () => {
-    const title = titleInput.value
-    window.electronAPI.setTitle(title)
-});
-```
-
-At this point, your demo should be fully functional. Try using the input field and see what happens
-to your BrowserWindow title!
-
-## Pattern 2: Renderer to main (two-way)
-
-A common application for two-way IPC is calling a main process module from your renderer process
-code and waiting for a result. This can be done by using [`ipcRenderer.invoke`] paired with
-[`ipcMain.handle`].
-
-In the following example, we'll be opening a native file dialog from the renderer process and
-returning the selected file's path.
-
-For this demo, you'll need to add code to your main process, your renderer process, and a preload
-script. The full code is below, but we'll be explaining each file individually in the following
-sections.
-
-```fiddle docs/fiddles/ipc/pattern-2
-```
-
-### 1. Listen for events with `ipcMain.handle`
-
-In the main process, we'll be creating a `handleFileOpen()` function that calls
-`dialog.showOpenDialog` and returns the value of the file path selected by the user. This function
-is used as a callback whenever an `ipcRender.invoke` message is sent through the `dialog:openFile`
-channel from the renderer process. The return value is then returned as a Promise to the original
-`invoke` call.
-
-:::caution A word on error handling
-Errors thrown through `handle` in the main process are not transparent as they
-are serialized and only the `message` property from the original error is
-provided to the renderer process. Please refer to
-[#24427](https://github.com/electron/electron/issues/24427) for details.
-:::
-
-```javascript {6-13,25} title='main.js (Main Process)'
-const { BrowserWindow, dialog, ipcMain } = require('electron')
-const path = require('path')
-
-//...
-
-async function handleFileOpen() {
-  const { canceled, filePaths } = await dialog.showOpenDialog()
-  if (canceled) {
-    return
-  } else {
-    return filePaths[0]
-  }
-}
-
-function createWindow () {
-  const mainWindow = new BrowserWindow({
-    webPreferences: {
-      preload: path.join(__dirname, 'preload.js')
-    }
-  })
-  mainWindow.loadFile('index.html')
-}
-
-app.whenReady(() => {
-  ipcMain.handle('dialog:openFile', handleFileOpen)
-  createWindow()
-})
-//...
-```
-
-:::tip on channel names
-The `dialog:` prefix on the IPC channel name has no effect on the code. It only serves
-as a namespace that helps with code readability.
-:::
-
-:::info
-Make sure you're loading the `index.html` and `preload.js` entry points for the following steps!
-:::
-
-### 2. Expose `ipcRenderer.invoke` via preload
-
-In the preload script, we expose a one-line `openFile` function that calls and returns the value of
-`ipcRenderer.invoke('dialog:openFile')`. We'll be using this API in the next step to call the
-native dialog from our renderer's user interface.
-
-```javascript title='preload.js (Preload Script)'
-const { contextBridge, ipcRenderer } = require('electron')
-
-contextBridge.exposeInMainWorld('electronAPI', {
-  openFile: () => ipcRenderer.invoke('dialog:openFile')
-})
-```
-
-:::caution Security warning
-We don't directly expose the whole `ipcRenderer.invoke` API for [security reasons]. Make sure to
-limit the renderer's access to Electron APIs as much as possible.
-:::
-
-### 3. Build the renderer process UI
-
-Finally, let's build the HTML file that we load into our BrowserWindow.
-
-```html {10-11} 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'">
-    <title>Dialog</title>
-  </head>
-  <body>
-    <button type="button" id="btn">Open a File</button>
-    File path: <strong id="filePath"></strong>
-    <script src='./renderer.js'></script>
-  </body>
-</html>
-```
-
-The UI consists of a single `#btn` button element that will be used to trigger our preload API, and
-a `#filePath` element that will be used to display the path of the selected file. Making these
-pieces work will take a few lines of code in the renderer process script:
-
-```javascript title='renderer.js (Renderer Process)'
-const btn = document.getElementById('btn')
-const filePathElement = document.getElementById('filePath')
-
-btn.addEventListener('click', async () => {
-  const filePath = await window.electronAPI.openFile()
-  filePathElement.innerText = filePath
-})
-```
-
-In the above snippet, we listen for clicks on the `#btn` button, and call our
-`window.electronAPI.openFile()` API to activate the native Open File dialog. We then display the
-selected file path in the `#filePath` element.
-
-### Note: legacy approaches
-
-The `ipcRenderer.invoke` API was added in Electron 7 as a developer-friendly way to tackle two-way
-IPC from the renderer process. However, there exist a couple alternative approaches to this IPC
-pattern.
-
-:::warning Avoid legacy approaches if possible
-We recommend using `ipcRenderer.invoke` whenever possible. The following two-way renderer-to-main
-patterns are documented for historical purposes.
-:::
-
-:::info
-For the following examples, we're calling `ipcRenderer` directly from the preload script to keep
-the code samples small.
-:::
-
-#### Using `ipcRenderer.send`
-
-The `ipcRenderer.send` API that we used for single-way communication can also be leveraged to
-perform two-way communication. This was the recommended way for asynchronous two-way communication
-via IPC prior to Electron 7.
-
-```javascript title='preload.js (Preload Script)'
-// You can also put expose this code to the renderer
-// process with the `contextBridge` API
-const { ipcRenderer } = require('electron')
-
-ipcRenderer.on('asynchronous-reply', (_event, arg) => {
-  console.log(arg) // prints "pong" in the DevTools console
-})
-ipcRenderer.send('asynchronous-message', 'ping')
-```
-
-```javascript title='main.js (Main Process)'
-ipcMain.on('asynchronous-message', (event, arg) => {
-  console.log(arg) // prints "ping" in the Node console
-  // works like `send`, but returning a message back
-  // to the renderer that sent the original message
-  event.reply('asynchronous-reply', 'pong')
-})
-```
-
-There are a couple downsides to this approach:
-
-* You need to set up a second `ipcRenderer.on` listener to handle the response in the renderer
-process. With `invoke`, you get the response value returned as a Promise to the original API call.
-* There's no obvious way to pair the `asynchronous-reply` message to the original
-`asynchronous-message` one. If you have very frequent messages going back and forth through these
-channels, you would need to add additional app code to track each call and response individually.
-
-#### Using `ipcRenderer.sendSync`
-
-The `ipcRenderer.sendSync` API sends a message to the main process and waits _synchronously_ for a
-response.
-
-```javascript title='main.js (Main Process)'
-const { ipcMain } = require('electron')
-ipcMain.on('synchronous-message', (event, arg) => {
-  console.log(arg) // prints "ping" in the Node console
-  event.returnValue = 'pong'
-})
-```
-
-```javascript title='preload.js (Preload Script)'
-// You can also put expose this code to the renderer
-// process with the `contextBridge` API
-const { ipcRenderer } = require('electron')
-
-const result = ipcRenderer.sendSync('synchronous-message', 'ping')
-console.log(result) // prints "pong" in the DevTools console
-```
-
-The structure of this code is very similar to the `invoke` model, but we recommend
-**avoiding this API** for performance reasons. Its synchronous nature means that it'll block the
-renderer process until a reply is received.
-
-## Pattern 3: Main to renderer
-
-When sending a message from the main process to a renderer process, you need to specify which
-renderer is receiving the message. Messages need to be sent to a renderer process
-via its [`WebContents`] instance. This WebContents instance contains a [`send`][webcontents-send] method
-that can be used in the same way as `ipcRenderer.send`.
-
-To demonstrate this pattern, we'll be building a number counter controlled by the native operating
-system menu.
-
-For this demo, you'll need to add code to your main process, your renderer process, and a preload
-script. The full code is below, but we'll be explaining each file individually in the following
-sections.
-
-```fiddle docs/fiddles/ipc/pattern-3
-```
-
-### 1. Send messages with the `webContents` module
-
-For this demo, we'll need to first build a custom menu in the main process using Electron's `Menu`
-module that uses the `webContents.send` API to send an IPC message from the main process to the
-target renderer.
-
-```javascript {11-26} title='main.js (Main Process)'
-const {app, BrowserWindow, Menu, ipcMain} = require('electron')
-const path = require('path')
-
-function createWindow () {
-  const mainWindow = new BrowserWindow({
-    webPreferences: {
-      preload: path.join(__dirname, 'preload.js')
-    }
-  })
-
-  const menu = Menu.buildFromTemplate([
-    {
-      label: app.name,
-      submenu: [
-        {
-          click: () => mainWindow.webContents.send('update-counter', 1),
-          label: 'Increment',
-        },
-        {
-          click: () => mainWindow.webContents.send('update-counter', -1),
-          label: 'Decrement',
-        }
-      ]
-    }
-  ])
-  Menu.setApplicationMenu(menu)
-
-  mainWindow.loadFile('index.html')
-}
-//...
-
-```
-
-For the purposes of the tutorial, it's important to note that the `click` handler
-sends a message (either `1` or `-1`) to the renderer process through the `update-counter` channel.
-
-```javascript
-click: () => mainWindow.webContents.send('update-counter', -1)
-```
-
-:::info
-Make sure you're loading the `index.html` and `preload.js` entry points for the following steps!
-:::
-
-### 2. Expose `ipcRenderer.on` via preload
-
-Like in the previous renderer-to-main example, we use the `contextBridge` and `ipcRenderer`
-modules in the preload script to expose IPC functionality to the renderer process:
-
-```javascript title='preload.js (Preload Script)'
-const { contextBridge, ipcRenderer } = require('electron')
-
-contextBridge.exposeInMainWorld('electronAPI', {
-    onUpdateCounter: (callback) => ipcRenderer.on('update-counter', callback)
-})
-```
-
-After loading the preload script, your renderer process should have access to the
-`window.electronAPI.onUpdateCounter()` listener function.
-
-:::caution Security warning
-We don't directly expose the whole `ipcRenderer.on` API for [security reasons]. Make sure to
-limit the renderer's access to Electron APIs as much as possible.
-:::
-
-:::info
-In the case of this minimal example, you can call `ipcRenderer.on` directly in the preload script
-rather than exposing it over the context bridge.
-
-```javascript title='preload.js (Preload Script)'
-const { ipcRenderer } = require('electron')
-
-window.addEventListener('DOMContentLoaded', () => {
-    const counter = document.getElementById('counter')
-    ipcRenderer.on('update-counter', (_event, value) => {
-        const oldValue = Number(counter.innerText)
-        const newValue = oldValue + value
-        counter.innerText = newValue
-    })
-})
-```
-
-However, this approach has limited flexibility compared to exposing your preload APIs
-over the context bridge, since your listener can't directly interact with your renderer code.
-:::
-
-### 3. Build the renderer process UI
-
-To tie it all together, we'll create an interface in the loaded HTML file that contains a
-`#counter` element that we'll use to display the values:
-
-```html {10} 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'">
-    <title>Menu Counter</title>
-  </head>
-  <body>
-    Current value: <strong id="counter">0</strong>
-    <script src="./renderer.js"></script>
-  </body>
-</html>
-```
-
-Finally, to make the values update in the HTML document, we'll add a few lines of DOM manipulation
-so that the value of the `#counter` element is updated whenever we fire an `update-counter` event.
-
-```javascript title='renderer.js (Renderer Process)'
-const counter = document.getElementById('counter')
-
-window.electronAPI.onUpdateCounter((_event, value) => {
-    const oldValue = Number(counter.innerText)
-    const newValue = oldValue + value
-    counter.innerText = newValue
-})
-```
-
-In the above code, we're passing in a callback to the `window.electronAPI.onUpdateCounter` function
-exposed from our preload script. The second `value` parameter corresponds to the `1` or `-1` we
-were passing in from the `webContents.send` call from the native menu.
-
-### Optional: returning a reply
-
-There's no equivalent for `ipcRenderer.invoke` for main-to-renderer IPC. Instead, you can
-send a reply back to the main process from within the `ipcRenderer.on` callback.
-
-We can demonstrate this with slight modifications to the code from the previous example. In the
-renderer process, use the `event` parameter to send a reply back to the main process through the
-`counter-value` channel.
-
-```javascript title='renderer.js (Renderer Process)'
-const counter = document.getElementById('counter')
-
-window.electronAPI.onUpdateCounter((event, value) => {
-  const oldValue = Number(counter.innerText)
-  const newValue = oldValue + value
-  counter.innerText = newValue
-  event.sender.send('counter-value', newValue)
-})
-```
-
-In the main process, listen for `counter-value` events and handle them appropriately.
-
-```javascript title='main.js (Main Process)'
-//...
-ipcMain.on('counter-value', (_event, value) => {
-  console.log(value) // will print value to Node console
-})
-//...
-```
-
-## Pattern 4: Renderer to renderer
-
-There's no direct way to send messages between renderer processes in Electron using the `ipcMain`
-and `ipcRenderer` modules. To achieve this, you have two options:
-
-* Use the main process as a message broker between renderers. This would involve sending a message
-from one renderer to the main process, which would forward the message to the other renderer.
-* Pass a [MessagePort] from the main process to both renderers. This will allow direct communication
-between renderers after the initial setup.
-
-## Object serialization
-
-Electron's IPC implementation uses the HTML standard
-[Structured Clone Algorithm][sca] to serialize objects passed between processes, meaning that
-only certain types of objects can be passed through IPC channels.
-
-In particular, DOM objects (e.g. `Element`, `Location` and `DOMMatrix`), Node.js objects
-backed by C++ classes (e.g. `process.env`, some members of `Stream`), and Electron objects
-backed by C++ classes (e.g. `WebContents`, `BrowserWindow` and `WebFrame`) are not serializable
-with Structured Clone.

-### 17. Validate the `sender` of all IPC messages
-
-You should always validate incoming IPC messages `sender` property to ensure you
-aren't performing actions or sending information to untrusted renderers.
-
-#### Why?
-
-All Web Frames can in theory send IPC messages to the main process, including
-iframes and child windows in some scenarios.  If you have an IPC message that returns
-user data to the sender via `event.reply` or performs privileged actions that the renderer
-can't natively, you should ensure you aren't listening to third party web frames.
-
-You should be validating the `sender` of **all** IPC messages by default.
-
-#### How?
-
-```js title='main.js (Main Process)'
-// Bad
-ipcMain.handle('get-secrets', () => {
-  return getSecrets();
-});
-
-// Good

+
+## Supported Versions
+
+_**Note:** Beginning in September 2021 with Electron 15, the Electron team
+will temporarily support the latest **four** stable major versions. This
+extended support is intended to help Electron developers transition to
+the [new eight week release cadence](https://electronjs.org/blog/8-week-cadence), and will continue until May 2022, with
+the release of Electron 19. At that time, the Electron team will drop support
+back to the latest three stable major versions._
+
+The latest three *stable* major versions are supported by the Electron team.
+For example, if the latest release is 6.1.x, then the 5.0.x as well
+as the 4.2.x series are supported.  We only support the latest minor release
+for each stable release series.  This means that in the case of a security fix
+6.1.x will receive the fix, but we will not release a new version of 6.0.x.
+
+The latest stable release unilaterally receives all fixes from `main`,
+and the version prior to that receives the vast majority of those fixes
+as time and bandwidth warrants. The oldest supported release line will receive
+only security fixes directly.
+
+All supported release lines will accept external pull requests to backport
+fixes previously merged to `main`, though this may be on a case-by-case
+basis for some older supported lines. All contested decisions around release
+line backports will be resolved by the [Releases Working Group](https://github.com/electron/governance/tree/main/wg-releases) as an agenda item at their weekly meeting the week the backport PR is raised.
+
+When an API is changed or removed in a way that breaks existing functionality, the
+previous functionality will be supported for a minimum of two major versions when
+possible before being removed. For example, if a function takes three arguments,
+and that number is reduced to two in major version 10, the three-argument version would
+continue to work until, at minimum, major version 12. Past the minimum two-version
+threshold, we will attempt to support backwards compatibility beyond two versions
+until the maintainers feel the maintenance burden is too high to continue doing so.
+
+### Currently supported versions
+
+* 18.x.y
+* 17.x.y
+* 16.x.y
+* 15.x.y
+
+### End-of-life
+
+When a release branch reaches the end of its support cycle, the series
+will be deprecated in NPM and a final end-of-support release will be
+made. This release will add a warning to inform that an unsupported
+version of Electron is in use.
+
+These steps are to help app developers learn when a branch they're
+using becomes unsupported, but without being excessively intrusive
+to end users.
+
+If an application has exceptional circumstances and needs to stay
+on an unsupported series of Electron, developers can silence the
+end-of-support warning by omitting the final release from the app's
+`package.json` `devDependencies`. For example, since the 1-6-x series
+ended with an end-of-support 1.6.18 release, developers could choose
+to stay in the 1-6-x series without warnings with `devDependency` of
+`"electron": 1.6.0 - 1.6.17`.
+
+## Supported Platforms
+
+Following platforms are supported by Electron:
+
+### macOS
+
+Only 64bit binaries are provided for macOS, and the minimum macOS version
+supported is macOS 10.11 (El Capitan).
+
+Native support for Apple Silicon (`arm64`) devices was added in Electron 11.0.0.
+
+### Windows
+
+Windows 7 and later are supported, older operating systems are not supported
+(and do not work).
+
+Both `ia32` (`x86`) and `x64` (`amd64`) binaries are provided for Windows.
+[Native support for Windows on Arm (`arm64`) devices was added in Electron 6.0.8.](windows-arm.md).
+Running apps packaged with previous versions is possible using the ia32 binary.
+
+### Linux
+
+The prebuilt binaries of Electron are built on Ubuntu 18.04.
+
+Whether the prebuilt binary can run on a distribution depends on whether the
+distribution includes the libraries that Electron is linked to on the building
+platform, so only Ubuntu 18.04 is guaranteed to work, but following platforms
+are also verified to be able to run the prebuilt binaries of Electron:
+
+* Ubuntu 14.04 and newer
+* Fedora 24 and newer
+* Debian 8 and newer
