+# Recent Documents (Windows & macOS)
+
+Windows and macOS provide easy access to a list of recent documents opened by
+the application via JumpList or dock menu, respectively.
+
+__JumpList:__
+
+![JumpList Recent Files][jumplist-image]
+
+__Application dock menu:__
+
+![macOS Dock Menu][dock-menu-image]
+
+To add a file to recent documents, you can use the
+[app.addRecentDocument][addrecentdocument] API:
+
+```javascript
+const { app } = require('electron')
+app.addRecentDocument('/Users/USERNAME/Desktop/work.type')
+```
+
+And you can use [app.clearRecentDocuments][clearrecentdocuments] API to empty
+the recent documents list:
+
+```javascript
+const { app } = require('electron')
+app.clearRecentDocuments()
+```
+
+## Windows Notes
+
+In order to be able to use this feature on Windows, your application has to be
+registered as a handler of the file type of the document, otherwise the file
+won't appear in JumpList even after you have added it. You can find everything
+on registering your application in [Application Registration][app-registration].
+
+When a user clicks a file from the JumpList, a new instance of your application
+will be started with the path of the file added as a command line argument.
+
+## macOS Notes
+
+When a file is requested from the recent documents menu, the `open-file` event
+of `app` module will be emitted for it.
