+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
 
-[homepage]: https://contributor-covenant.org
-[version]: https://contributor-covenant.org/version/1/4/
+#### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+#### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+#### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+#### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.

-Electron a completely separate product from NW.js:
-
-__1. Entry of Application__
-
-In NW.js the main entry point of an application is a web page or a JS script. You specify a

-
-In Electron, the entry point is a JavaScript script. Instead of
-providing a URL directly, you manually create a browser window and load
-an HTML file using the API. You also need to listen to window events
-to decide when to quit the application.
-
-Electron works more like the Node.js runtime. Electron's APIs are lower level
-so you can use it for browser testing in place of [PhantomJS](http://phantomjs.org/).
-
-__2. Build System__
-
-In order to avoid the complexity of building all of Chromium, Electron uses [`libchromiumcontent`](https://github.com/electron/libchromiumcontent) to access
-Chromium's Content API. `libchromiumcontent` is a single shared library that
-includes the Chromium Content module and all of its dependencies. Users don't
-need a powerful machine to build Electron.

-__3. Node Integration__

+# Technical Differences Between Electron and NW.js
+
+Like [NW.js][nwjs], Electron provides a platform to write desktop applications with web
+technologies. Both platforms enable developers to utilize HTML, JavaScript, and
+Node.js. On the surface, they seem very similar.
+
+There are however fundamental differences between the two projects that make
+Electron a completely separate product from NW.js.
+
+## 1) Entry of Application
+
+In NW.js, the main entry point of an application can be an HTML web page. In
+that case, NW.js will open the given entry point in a browser window.
+
+In Electron, the entry point is always a JavaScript script. Instead of providing a
+URL directly, you manually create a browser window and load an HTML file using
+the API. You also need to listen to window events to decide when to quit the
+application.
+
+Electron works more like the Node.js runtime. Electron's APIs are lower level so
+you can use it for browser testing in place of
+[PhantomJS](http://phantomjs.org/).
+
+## 2) Node Integration
+
+In NW.js, the Node integration in web pages requires patching Chromium to work,
+while in Electron we chose a different way to integrate the `libuv` loop with
+each platform's message loop to avoid hacking Chromium. See the
+[`node_bindings`][node-bindings] code for how that was done.
+
+## 3) JavaScript Contexts
+
+If you are an experienced NW.js user, you should be familiar with the concept of
+Node context and web context. These concepts were invented because of how NW.js
+was implemented.
+
+By using the
+[multi-context](https://github.com/nodejs/node-v0.x-archive/commit/756b622)
+feature of Node, Electron doesn't introduce a new JavaScript context in web
+pages.
+
+Note: NW.js has optionally supported multi-context since 0.13.
+
+## 4) Legacy Support
+
+NW.js still offers a "legacy release" that supports Windows XP. It doesn't
+receive security updates.
+
+Given that hardware manufacturers, Microsoft, Chromium, and Node.js haven't
+released even critical security updates for that system, we have to warn you
+that using Windows XP is wildly insecure and outright irresponsible.
+
+However, we understand that requirements outside our wildest imagination may
+exist, so if you're looking for something like Electron that runs on Windows XP,
+the NW.js legacy release might be the right fit for you.
+
+## 5) Features
+
+There are numerous differences in the amount of supported features. Electron has
+a bigger community, more production apps using it, and [a large amount of
+userland modules available on npm][electron-modules].
+
+As an example, Electron has built-in support for automatic updates and countless
+tools that make the creation of installers easier. As an example in favor of
+NW.js, NW.js supports more `Chrome.*` APIs for the development of Chrome Apps.
+
+Naturally, we believe that Electron is the better platform for polished
+production applications built with web technologies (like Visual Studio Code,
+Slack, or Facebook Messenger); however, we want to be fair to our web technology
+friends. If you have feature needs that Electron does not meet, you might want
+to try NW.js.

-# About Electron
-
-[Electron](https://electronjs.org) is an open source library developed by GitHub for building cross-platform desktop applications with HTML, CSS, and JavaScript. Electron accomplishes this by combining [Chromium](https://www.chromium.org/Home) and [Node.js](https://nodejs.org) into a single runtime and apps can be packaged for Mac, Windows, and Linux.
-
-Electron began in 2013 as the framework on which [Atom](https://atom.io), GitHub's hackable text editor, would be built. The two were open sourced in the Spring of 2014.
-
-It has since become a popular tool used by open source developers, startups, and established companies. [See who is building on Electron](https://electronjs.org/apps).
-
-Read on to learn more about the contributors and releases of Electron or get started building with Electron in the [Quick Start Guide](quick-start.md).
-
-## Core Team and Contributors
-
-Electron is maintained by a team at GitHub as well as a group of [active contributors](https://github.com/electron/electron/graphs/contributors) from the community. Some of the contributors are individuals and some work at larger companies who are developing on Electron. We're happy to add frequent contributors to the project as maintainers. Read more about [contributing to Electron](https://github.com/electron/electron/blob/master/CONTRIBUTING.md).
-
-## Releases
-
-[Electron releases](https://github.com/electron/electron/releases) frequently. We release when there are significant bug fixes, new APIs or are updating versions of Chromium or Node.js.
-
-### Updating Dependencies
-
-Electron's version of Chromium is usually updated within one or two weeks after a new stable Chromium version is released, depending on the effort involved in the upgrade.
-
-When a new version of Node.js is released, Electron usually waits about a month before upgrading in order to bring in a more stable version.
-
-In Electron, Node.js and Chromium share a single V8 instance—usually the version that Chromium is using. Most of the time this _just works_ but sometimes it means patching Node.js.
-
-### Versioning
-
-As of version 2.0 Electron [follows `semver`](https://semver.org).
-For most applications, and using any recent version of npm,
-running `$ npm install electron` will do the right thing.
-
-The version update process is detailed explicitly in our [Versioning Doc](electron-versioning.md).
-
-### LTS
-
-Long term support of older versions of Electron does not currently exist. If your current version of Electron works for you, you can stay on it for as long as you'd like. If you want to make use of new features as they come in you should upgrade to a newer version.
-
-A major update came with version `v1.0.0`. If you're not yet using this version, you should [read more about the `v1.0.0` changes](https://electronjs.org/blog/electron-1-0).
-
-## Core Philosophy
-
-In order to keep Electron small (file size) and sustainable (the spread of dependencies and APIs) the project limits the scope of the core project.
-
-For instance, Electron uses Chromium's rendering library rather than all of Chromium. This makes it easier to upgrade Chromium but also means some browser features found in Google Chrome do not exist in Electron.
-
-New features added to Electron should primarily be native APIs. If a feature can be its own Node.js module, it probably should be. See the [Electron tools built by the community](https://electronjs.org/community).
-

-# Signing macOS builds
+# Signing & notarizing macOS builds
 
-Before signing macOS builds, you must do the following:
+Properly preparing macOS applications for release requires two steps: First, the
+app needs to be code-signed. Then, the app needs to be uploaded to Apple for a
+process called "notarization", where automated systems will further verify that
+your app isn't doing anything to endanger its users.
+
+To start the process, ensure that you fulfill the requirements for signing and
+notarizing your app:
 
 1. Enroll in the [Apple Developer Program] (requires an annual fee)
-2. Download and install [Xcode]
+2. Download and install [Xcode] - this requires a computer running macOS
 3. Generate, download, and install [signing certificates]
 
-There are a number of tools for signing your packaged app:
+Electron's ecosystem favors configuration and freedom, so there are multiple
+ways to get your application signed and notarized.
 
-- [`electron-osx-sign`] is a standalone tool for signing macOS packages.
-- [`electron-packager`] bundles `electron-osx-sign`. If you're using `electron-packager`,
-pass the `--osx-sign=true` flag to sign your build.
-  - [`electron-forge`] uses `electron-packager` internally, you can set the `osxSign` option
-    in your forge config.
-- [`electron-builder`] has built-in code-signing capabilities. See [electron.build/code-signing](https://www.electron.build/code-signing)
+## `electron-forge`
 
-## Notarization
+If you're using Electron's favorite build tool, getting your application signed
+and notarized requires a few additions to your configuration. [Forge](https://electronforge.io) is a
+collection of the official Electron tools, using [`electron-packager`],
+[`electron-osx-sign`], and [`electron-notarize`] under the hood.
 
-Starting with macOS Catalina, Apple requires applications to be notarized.
-"Notarization" as defined by Apple means that you upload your previously signed
-application to Apple for additional verification _before_ distributing the app
-to your users.
+Let's take a look at an example configuration with all required fields. Not all
+of them are required: the tools will be clever enough to automatically find a
+suitable `identity`, for instance, but we recommend that you are explicit.
 
-To automate this process, you can use the [`electron-notarize`] module. You
-do not necessarily need to complete this step for every build you make – just
-the builds you intend to ship to users.

+
+## `electron-packager`
+
+If you're not using an integrated build pipeline like Forge or Builder, you
+are likely using [`electron-packager`], which includes [`electron-osx-sign`] and
+[`electron-notarize`].
+
+If you're using Packager's API, you can pass [in configuration that both signs
+and notarizes your
+application](https://electron.github.io/electron-packager/master/interfaces/electronpackager.options.html).
+
+```js
+const packager = require('electron-packager')
+
+packager({
+  dir: '/path/to/my/app',
+  osxSign: {
+    identity: 'Developer ID Application: Felix Rieseberg (LT94ZKYDCJ)',
+    'hardened-runtime': true,
+    entitlements: 'entitlements.plist',
+    'entitlements-inherit': 'entitlements.plist',
+    'signature-flags': 'library'
+  },
+  osxNotarize: {
+    appleId: 'felix@felix.fun',
+    appleIdPassword: 'my-apple-id-password'
+  }
+})
+```

+Since Electron 8, stabilization branches are always **major** version lines, and named against the following template `$MAJOR-x-y` e.g. `8-x-y`.  Prior to that we used **minor** version lines and named them as `$MAJOR-$MINOR-x` e.g. `2-0-x`

+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
