+# JumpListCategory Object
+
+* `type` String (optional) - One of the following:
+  * `tasks` - Items in this category will be placed into the standard `Tasks`
+    category. There can be only one such category, and it will always be
+    displayed at the bottom of the Jump List.
+  * `frequent` - Displays a list of files frequently opened by the app, the
+    name of the category and its items are set by Windows.
+  * `recent` - Displays a list of files recently opened by the app, the name
+    of the category and its items are set by Windows. Items may be added to
+    this category indirectly using `app.addRecentDocument(path)`.
+  * `custom` - Displays tasks or file links, `name` must be set by the app.
+* `name` String (optional) - Must be set if `type` is `custom`, otherwise it should be
+  omitted.
+* `items` JumpListItem[] (optional) - Array of [`JumpListItem`](jump-list-item.md) objects if `type` is `tasks` or
+  `custom`, otherwise it should be omitted.
+
+**Note:** If a `JumpListCategory` object has neither the `type` nor the `name`
+property set then its `type` is assumed to be `tasks`. If the `name` property
+is set but the `type` property is omitted then the `type` is assumed to be
+`custom`.
