+```
+
+ * **switchToTab(params = {})**
+
+Switch to a tab (sets it as the currently selected tab).

 ```
 
 ## Styling the navigator
 }
 ```
 
+## Styling the tab bar
+
+You can style the tab bar appearance by passing a `tabsStyle` object when the app is originally created (on `startTabBasedApp`).
+
+```js
+Navigation.startTabBasedApp({
+  tabs: [ ... ],
+  tabsStyle: { // optional, add this if you want to style the tab bar beyond the defaults
+    tabBarButtonColor: '#ff0000'
+  }
+});
+```
+
+#### Style object format
+
+```js
+{
+  tabBarButtonColor: '#ffff00', // change the color of the tab icons and text (also unselected)
+  tabBarSelectedButtonColor: '#ff9900', // change the color of the selected tab icon and text (only selected)
+  tabBarBackgroundColor: '#551A8B' // change the background color of the tab bar
+}
+```
+
+All supported styles are defined [here](https://github.com/wix/react-native-controllers#styling-tab-bar). There's also an example project there showcasing all the different styles.

 ## Deep links
 
 Deep links are strings which represent internal app paths/routes. They commonly appear on push notification payloads to control which section of the app should be displayed when the notification is clicked. For example, in a chat app, clicking on the notification should open the relevant conversation on the "chats" tab.
