+## Docs Translations
+
+This directory once contained unstructured translations of Electron's 
+documentation, but has been deprecated in favor of a new translation process 
+using [Crowdin], a GitHub-friendly platform for collaborative translation.
+
+For more details, visit the [electron/i18n] repo.
+
+## Contributing
+
+If you're interested in helping translate Electron's docs, visit 
+[Crowdin] and log in with your GitHub account. And thanks!
+
+## Offline Docs
+
+If you miss having access to Electron's raw markdown files in your preferred
+language, don't fret! You can still get raw docs, they're just in a 
+different place now. See [electron/i18n/tree/master/content]
+
+To more easily view and browse offline docs in your language, clone the repo and use [vmd], 
+an Electron-based GitHub-styled markdown viewer:

+# Breaking changes (NetworkService) (Draft)
+
+This document describes changes to Electron APIs after migrating network code
+to NetworkService API.
+
+We don't currently have an estimate of when we will enable `NetworkService` by
+default in Electron, but as Chromium is already removing non-`NetworkService`
+code, we might switch before Electron 10.
+
+The content of this document should be moved to `breaking-changes.md` once we have
+determined when to enable `NetworkService` in Electron.

-### Types of Breaking Changes
+## `FIXME` comments
 
-This document uses the following convention to categorize breaking changes:
-
-- **API Changed:** An API was changed in such a way that code that has not been updated is guaranteed to throw an exception.
-- **Behavior Changed:** The behavior of Electron has changed, but not in such a way that an exception will necessarily be thrown.
-- **Default Changed:** Code depending on the old default may break, not necessarily throwing an exception. The old behavior can be restored by explicitly specifying the value.
-- **Deprecated:** An API was marked as deprecated. The API will continue to function, but will emit a deprecation warning, and will be removed in a future release.
-- **Removed:** An API or feature was removed, and is no longer supported by Electron.
-
-## Planned Breaking API Changes (12.0)
-
-### Removed: `crashReporter` methods in the renderer process
-
-The following `crashReporter` methods are no longer available in the renderer
-process:
-
-- `crashReporter.start`
-- `crashReporter.getLastCrashReport`
-- `crashReporter.getUploadedReports`
-- `crashReporter.getUploadToServer`
-- `crashReporter.setUploadToServer`
-- `crashReporter.getCrashesDirectory`
-
-They should be called only from the main process.
-
-See [#23265](https://github.com/electron/electron/pull/23265) for more details.
-
-## Planned Breaking API Changes (11.0)
-
-## Planned Breaking API Changes (10.0)
-
-### Deprecated: `companyName` argument to `crashReporter.start()`
-
-The `companyName` argument to `crashReporter.start()`, which was previously
-required, is now optional, and further, is deprecated. To get the same
-behavior in a non-deprecated way, you can pass a `companyName` value in
-`globalExtra`.
-
-```js
-// Deprecated in Electron 10
-crashReporter.start({ companyName: 'Umbrella Corporation' })
-// Replace with
-crashReporter.start({ globalExtra: { _companyName: 'Umbrella Corporation' } })
-```
-
-### Deprecated: `crashReporter.getCrashesDirectory()`
-
-The `crashReporter.getCrashesDirectory` method has been deprecated. Usage
-should be replaced by `app.getPath('crashDumps')`.
-
-```js
-// Deprecated in Electron 10
-crashReporter.getCrashesDirectory()
-// Replace with
-app.getPath('crashDumps')
-```
-
-### Deprecated: `crashReporter` methods in the renderer process
-
-Calling the following `crashReporter` methods from the renderer process is
-deprecated:
-
-- `crashReporter.start`
-- `crashReporter.getLastCrashReport`
-- `crashReporter.getUploadedReports`
-- `crashReporter.getUploadToServer`
-- `crashReporter.setUploadToServer`
-- `crashReporter.getCrashesDirectory`
-
-The only non-deprecated methods remaining in the `crashReporter` module in the
-renderer are `addExtraParameter`, `removeExtraParameter` and `getParameters`.
-
-All above methods remain non-deprecated when called from the main process.
-
-See [#23265](https://github.com/electron/electron/pull/23265) for more details.
-
-### Removed: Browser Window Affinity
-
-The `affinity` option when constructing a new `BrowserWindow` will be removed
-as part of our plan to more closely align with Chromium's process model for security,
-performance and maintainability.
-
-For more detailed information see [#18397](https://github.com/electron/electron/issues/18397).
-
-### Default Changed: `enableRemoteModule` defaults to `false`
-
-In Electron 9, using the remote module without explicitly enabling it via the
-`enableRemoteModule` WebPreferences option began emitting a warning. In
-Electron 10, the remote module is now disabled by default. To use the remote
-module, `enableRemoteModule: true` must be specified in WebPreferences:
-
-```js
-const w = new BrowserWindow({
-  webPreferences: {
-    enableRemoteModule: true
-  }
-})
-```
-
-We [recommend moving away from the remote
-module](https://medium.com/@nornagon/electrons-remote-module-considered-harmful-70d69500f31).

-## Planned Breaking API Changes (9.0)
-
-### Default Changed: Loading non-context-aware native modules in the renderer process is disabled by default
-
-As of Electron 9 we do not allow loading of non-context-aware native modules in
-the renderer process.  This is to improve security, performance and maintainability
-of Electron as a project.
-
-If this impacts you, you can temporarily set `app.allowRendererProcessReuse` to `false`
-to revert to the old behavior.  This flag will only be an option until Electron 11 so
-you should plan to update your native modules to be context aware.
-
-For more detailed information see [#18397](https://github.com/electron/electron/issues/18397).
-
-### Removed: `<webview>.getWebContents()`
-
-This API, which was deprecated in Electron 8.0, is now removed.
-
-```js
-// Removed in Electron 9.0
-webview.getWebContents()
-// Replace with
-const { remote } = require('electron')
-remote.webContents.fromId(webview.getWebContentsId())
-```
-
-### Removed: `webFrame.setLayoutZoomLevelLimits()`
-
-Chromium has removed support for changing the layout zoom level limits, and it
-is beyond Electron's capacity to maintain it. The function was deprecated in
-Electron 8.x, and has been removed in Electron 9.x. The layout zoom level limits
-are now fixed at a minimum of 0.25 and a maximum of 5.0, as defined
-[here](https://chromium.googlesource.com/chromium/src/+/938b37a6d2886bf8335fc7db792f1eb46c65b2ae/third_party/blink/common/page/page_zoom.cc#11).
-
-### Behavior Changed: Sending non-JS objects over IPC now throws an exception
-
-In Electron 8.0, IPC was changed to use the Structured Clone Algorithm,
-bringing significant performance improvements. To help ease the transition, the
-old IPC serialization algorithm was kept and used for some objects that aren't
-serializable with Structured Clone. 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. Whenever the old algorithm was invoked, a
-deprecation warning was printed.
-
-In Electron 9.0, the old serialization algorithm has been removed, and sending
-such non-serializable objects will now throw an "object could not be cloned"
-error.
-
-### API Changed: `shell.openItem` is now `shell.openPath`
-
-The `shell.openItem` API has been replaced with an asynchronous `shell.openPath` API.
-You can see the original API proposal and reasoning [here](https://github.com/electron/governance/blob/master/wg-api/spec-documents/shell-openitem.md).

-  * `companyName` String (optional) _Deprecated_ - Deprecated alias for

-  * `ignoreSystemCrashHandler` Boolean (optional) - If true, crashes generated

-  * `compress` Boolean (optional) _macOS_ _Windows_ - If true, crash reports
-    will be compressed and uploaded with `Content-Encoding: gzip`. Not all
-    collection servers support compressed payloads. Default is `false`.
-  * `extra` Record<String, String> (optional) - Extra string key/value
-    annotations that will be sent along with crash reports that are generated
-    in the main process. Only string values are supported. Crashes generated in
-    child processes will not contain these extra
-    parameters to crash reports generated from child processes, call
-    [`addExtraParameter`](#crashreporteraddextraparameterkey-value) from the
-    child process.
-  * `globalExtra` Record<String, String> (optional) - Extra string key/value
-    annotations that will be sent along with any crash reports generated in any
-    process. These annotations cannot be changed once the crash reporter has
-    been started. If a key is present in both the global extra parameters and
-    the process-specific extra parameters, then the global one will take
-    precedence. By default, `productName` and the app version are included, as
-    well as the Electron version.
+  * `uploadToServer` Boolean (optional) - Whether crash reports should be sent to the server. Default is `true`.
+  * `ignoreSystemCrashHandler` Boolean (optional) - Default is `false`.
+  * `extra` Record<String, String> (optional) - An object you can define that will be sent along with the
+    report. Only string properties are sent correctly. Nested objects are not
+    supported. When using Windows, the property names and values must be fewer than 64 characters.
+  * `crashesDirectory` String (optional) - Directory to store the crash reports temporarily (only used when the crash reporter is started via `process.crashReporter.start`).
 
-This method must be called before using any other `crashReporter` APIs. Once
-initialized this way, the crashpad handler collects crashes from all
-subsequently created processes. The crash reporter cannot be disabled once
-started.
+You are required to call this method before using any other `crashReporter` APIs
+and in each process (main/renderer) from which you want to collect crash reports.
+You can pass different options to `crashReporter.start` when calling from different processes.
 
-This method should be called as early as possible in app startup, preferably
-before `app.on('ready')`. If the crash reporter is not initialized at the time
-a renderer process is created, then that renderer process will not be monitored
-by the crash reporter.
+**Note** Child processes created via the `child_process` module will not have access to the Electron modules.
+Therefore, to collect crash reports from them, use `process.crashReporter.start` instead. Pass the same options as above
+along with an additional one called `crashesDirectory` that should point to a directory to store the crash
+reports temporarily. You can test this out by calling `process.crash()` to crash the child process.
 
-**Note:** You can test out the crash reporter by generating a crash using
-`process.crash()`.

-# Chrome Extension Support
-
-Electron supports a subset of the [Chrome Extensions
-API][chrome-extensions-api-index], primarily to support DevTools extensions and
-Chromium-internal extensions, but it also happens to support some other
-extension capabilities.
-
-[chrome-extensions-api-index]: https://developer.chrome.com/extensions/api_index
-
-> **Note:** Electron does not support arbitrary Chrome extensions from the
-> store, and it is a **non-goal** of the Electron project to be perfectly
-> compatible with Chrome's implementation of Extensions.
-
-## Loading extensions
-
-Electron only supports loading unpacked extensions (i.e., `.crx` files do not
-work). Extensions are installed per-`session`. To load an extension, call
-[`ses.loadExtension`](session.md#sesloadextensionpath):
-
-```js
-const { session } = require('electron')
-
-session.loadExtension('path/to/unpacked/extension').then(({ id }) => {
-  // ...
-})
-```
-
-Loaded extensions will not be automatically remembered across exits; if you do
-not call `loadExtension` when the app runs, the extension will not be loaded.
-
-Note that loading extensions is only supported in persistent sessions.
-Attempting to load an extension into an in-memory session will throw an error.
-
-See the [`session`](session.md) documentation for more information about
-loading, unloading, and querying active extensions.
-
-## Supported Extensions APIs

-additionally be supported, but support for any APIs not listed here is
-provisional and may be removed.

-
-### `chrome.tabs`
-
-The following methods of `chrome.tabs` are supported:
-
-- `chrome.tabs.sendMessage`
-- `chrome.tabs.executeScript`
-
-> **Note:** In Chrome, passing `-1` as a tab ID signifies the "currently active
-> tab". Since Electron has no such concept, passing `-1` as a tab ID is not

-Electron has a deployment of a custom Goma Backend that we make available to
-all Electron Maintainers.  See the [Access](#access) section below for details
-on authentication.
-
-## Enabling Goma
-
-Currently Electron Goma supports Windows, Linux, and macOS.  If you are
-on a supported platform you can enable goma by importing the `goma.gn` config
-file when using `gn`.
-
-```bash
-gn gen out/Testing --args="import(\"//electron/build/args/testing.gn\") import(\"//electron/build/args/goma.gn\")"
-```
-
-You must ensure that you do not have `cc_wrapper` configured, this means you
-can't use `sccache` or similar technology.
-
-Before you can use goma to build Electron you need to authenticate against
-the Goma service.  You only need to do this once per-machine.
-
-```bash
-cd electron/external_binaries/goma
-./goma_auth.py login
-```
-
-Once authenticated you need to make sure the goma daemon is running on your
-machine.
-
-```bash
-cd electron/external_binaries/goma
-./goma_ctl.py ensure_start
-```
-
-## Building with Goma
-
-When you are using Goma you can run `ninja` with a substantially higher `j`
-value than would normally be supported by your machine.
-
-Please do not set a value higher than **300** on Windows or Linux and
-**80** on macOS, we monitor the goma system and users found to be abusing
-it with unreasonable concurrency will be de-activated.
-
-```bash
-ninja -C out/Testing electron -j 200
-```
-
-## Monitoring Goma
-
-If you access [http://localhost:8088](http://localhost:8088) on your local
-machine you can monitor compile jobs as they flow through the goma system.
-
-## Access
-
-For security and cost reasons access to Electron Goma is currently restricted
-to Electron Maintainers.  If you want access please head to `#access-requests` in
-Slack and ping `@goma-squad` to ask for access.  Please be aware that being a
-maintainer does not *automatically* grant access and access is determined on a
-case by case basis.
