+## Extension Type AppMenuItem
+
+This extension type allows apps to register links to internal or external pages within the application switcher menu on the top left.
+
+### Configuration
+
+The Interface for an `AppMenuItemExtension` looks like so:
+
+```typescript
+interface AppMenuItemExtension {
+  id: string
+  type: 'appMenuItem'
+  extensionPointIds?: string[]
+  label: () => string
+  color?: string
+  handler?: () => void
+  icon?: string
+  path?: string
+  priority?: number
+  url?: string
+}
+```
+
+For `id`, `type`, and `extensionPointIds`, please see [extension base section]({{< ref "../_index.md#extension-base-configuration" >}}) in the top level docs.
+
+A `handler` will result in a `<button>` element. This is necessary when an action should be performed when clicking the menu item (e.g. opening a file editor).
+
+A `path` will result in a `<a>` element that links to an internal page. That means the given path needs to exist within the application.
+
+A `url` will result in a `<a>` element that links to an external page. External pages always open in a new tab or window.
+
+Since these properties are optional, the priority order is `handler` > `path` > `url`. At least one of them has to be provided when registering an extension.
+
+## Example
+
+The following example shows how an app creates an extension that registers an app menu item, linking to an internal page. All helper types and composables are being provided via the [web-pkg](https://github.com/owncloud/web/tree/master/packages/web-pkg) package.
+
+```typescript
+export default defineWebApplication({
+  setup() {
+    const { $gettext } = useGettext()
+    const appId = 'my-cool-app'
+
+    const menuItems = computed<AppMenuItemExtension[]>(() => [
+      {
+        id: 'com.github.owncloud.web.my-cool-app.menu-item',
+        type: 'appMenuItem',
+        label: () => $gettext('My cool app'),
+        path: urlJoin(appId),
+        icon: 'star',
+        color: '#0D856F',
+        priority: 60
+      }
+    ])
+
+    return {
+      appInfo: {
+        name: $gettext('My cool app'),
+        id: appId
+      },
+      extensions: menuItems
+    }
+  }
+})
+```
