+### Installing
+
+**CocoaPods**
+
+CocoaPods automates 3rd party dependencies in Objective-C.
+
+Install the ruby gem.
+
+```
+$ sudo gem install cocoapods
+$ pod setup
+```
+
+Depending on your Ruby installation, you may not have to run as sudo to install the cocoapods gem.
+Create a Podfile. You must be running on iOS 5 or above.
+
+```
+platform :ios, '5.0'
+pod 'KxMenu', '1'
+```
+
+Install dependencies.
+
+```
+$ pod install
+```
+
+When using CocoaPods, you must open the .xcworkspace file instead of the project file when building your project.
+
 ### Usage
 
 1. Drop files from KxMenu/Source folder in your project.
