 8 | # Requirements
 9 | This project works on iOS 8+ and requires ARC to build.
10 | 
11 | # Usage
12 | You can add the `AWNavigationMenuItem.h` and `AWNavigationMenuItem.m` source files to your project.
13 | 
14 | * Include AWNavigationMenuItem header. 
15 | `#import "AWNavigationMenuItem.h"`
16 | 
17 | * Initialize AWNavigationMenuItem.
18 | 
19 | ```objc
20 | AWNavigationMenuItem *menuItem = [[AWNavigationMenuItem alloc] init];
21 | menuItem.dataSource = self;
22 | menuItem.delegate = self;
23 | ```
24 | 
25 | * Implement the delegate and dataSource.
26 | 
27 | ```objc
