+# Testing Widevine CDM
+
+In Electron you can use the Widevine CDM library shipped with Chrome browser.
+
+## Getting the library
+
+Open `chrome://components/` in Chrome browser, find `Widevine Content Decryption Module`
+and make sure it is up to date, then you can find the library files from the
+application directory.
+
+### On Windows
+
+The library file `widevinecdm.dll` will be under
+`Program Files(x86)/Google/Chrome/Application/CHROME_VERSION/WidevineCdm/_platform_specific/win_(x86|x64)/`
+directory.
+
+### On MacOS
+
+The library file `libwidevinecdm.dylib` will be under
+`/Applications/Google Chrome.app/Contents/Versions/CHROME_VERSION/Google Chrome Framework.framework/Versions/A/Libraries/WidevineCdm/_platform_specific/mac_(x86|x64)/`
+directory.
+
+**Note:** Make sure that chrome version used by Electron is greater than or
+equal to the `min_chrome_version` value of Chrome's widevine cdm component.
+The value can be found in `manifest.json` under `WidevineCdm` directory.
+
+## Using the library
+
+After getting the library files, you should pass the path to the file
+with `--widevine-cdm-path` command line switch, and the library's version
+with `--widevine-cdm-version` switch. The command line switches have to be
+passed before the `ready` event of `app` module gets emitted.
+
+Example code:
+
+```javascript
+const {app, BrowserWindow} = require('electron')
+
+// You have to pass the directory that contains widevine library here, it is
+// * `libwidevinecdm.dylib` on macOS,
+// * `widevinecdm.dll` on Windows.
+app.commandLine.appendSwitch('widevine-cdm-path', '/path/to/widevine_library')
+// The version of plugin can be got from `chrome://plugins` page in Chrome.
+app.commandLine.appendSwitch('widevine-cdm-version', '1.4.8.866')
+
+let win = null
+app.on('ready', () => {
+  win = new BrowserWindow()
+  win.show()
+})
+```
+
+## Verifying Widevine CDM support
+
+To verify whether widevine works, you can use following ways:
+
+* Open https://shaka-player-demo.appspot.com/ and load a manifest that uses
+`Widevine`.
+* Open http://www.dash-player.com/demo/drm-test-area/, check whether the page
+says `bitdash uses Widevine in your browser`, then play the video.

-# Using Widevine CDM Plugin
-
-In Electron you can use the Widevine CDM plugin shipped with Chrome browser.
-
-## Getting the plugin
-
-Electron doesn't ship with the Widevine CDM plugin for license reasons, to get
-it, you need to install the official Chrome browser first, which should match
-the architecture and Chrome version of the Electron build you use.
-
-**Note:** The major version of Chrome browser has to be the same with the Chrome
-version used by Electron, otherwise the plugin will not work even though
-`navigator.plugins` would show it has been loaded.
-
-### Windows & macOS
-
-Open `chrome://components/` in Chrome browser, find `WidevineCdm` and make
-sure it is up to date, then you can find all the plugin binaries from the
-`Program Files(x86)/Google/Chrome/Application/VERSION/WidevineCDM/_platform_specific/PLATFORM_ARCH/`
-directory.
-
-`APP_DATA` is system's location for storing app data, on Windows it is
-`%LOCALAPPDATA%`, on macOS it is `~/Library/Application Support`. `VERSION` is
-Widevine CDM plugin's version string, like `1.4.8.866`. `PLATFORM` is `mac` or
-`win`. `ARCH` is `x86` or `x64`.
-
-On Windows the required binaries are `widevinecdm.dll` and
-`widevinecdmadapter.dll`, on macOS they are `libwidevinecdm.dylib` and
-`widevinecdmadapter.plugin`. You can copy them to anywhere you like, but they
-have to be put together.
-
-### Linux
-
-On Linux the plugin binaries are shipped together with Chrome browser, you can
-find them under `/opt/google/chrome`, the filenames are `libwidevinecdm.so` and
-`libwidevinecdmadapter.so`.
-
-## Using the plugin
-
-After getting the plugin files, you should pass the `widevinecdmadapter`'s path
-to Electron with `--widevine-cdm-path` command line switch, and the plugin's
-version with `--widevine-cdm-version` switch.
-
-**Note:** Though only the `widevinecdmadapter` binary is passed to Electron, the
-`widevinecdm` binary has to be put aside it.
-
-The command line switches have to be passed before the `ready` event of `app`
-module gets emitted, and the page that uses this plugin must have plugin
-enabled.
-
-Example code:
-
-```javascript
-const {app, BrowserWindow} = require('electron')
-
-// You have to pass the filename of `widevinecdmadapter` here, it is
-// * `widevinecdmadapter.plugin` on macOS,
-// * `libwidevinecdmadapter.so` on Linux,
-// * `widevinecdmadapter.dll` on Windows.
-app.commandLine.appendSwitch('widevine-cdm-path', '/path/to/widevinecdmadapter.plugin')
-// The version of plugin can be got from `chrome://plugins` page in Chrome.
-app.commandLine.appendSwitch('widevine-cdm-version', '1.4.8.866')
-
-let win = null
-app.on('ready', () => {
-  win = new BrowserWindow({
-    webPreferences: {
-      // The `plugins` have to be enabled.
-      plugins: true
-    }
-  })
-  win.show()
-})
-```
-
-## Verifying the plugin
-
-To verify whether the plugin works, you can use following ways:
-
-* Open devtools and check whether `navigator.plugins` includes the Widevine
-CDM plugin.
-* Open https://shaka-player-demo.appspot.com/ and load a manifest that uses
-`Widevine`.
-* Open http://www.dash-player.com/demo/drm-test-area/, check whether the page
-says `bitdash uses Widevine in your browser`, then play the video.
