 CocoaPods runs on [Ruby](http://www.ruby-lang.org/en/). To install it run the following commands:
 
-    $ sudo gem install cocoapods
-    $ pod setup
+```
+$ sudo gem install cocoapods
+$ pod setup
+```
+
+If you want to have CocoaPods generate documentation for each library, then install the [appledoc](http://gentlebytes.com/appledoc/) tool:
+
+```
+$ brew install appledoc --HEAD
+$ ln -sf "`brew --prefix`/Cellar/appledoc/HEAD/Templates" ~/Library/Application\ Support/appledoc

 Now that you've got CocoaPods installed you can easily add it to your project.

 After you've found your favorite dependencies you add them to your [Podfile](https://github.com/CocoaPods/CocoaPods/wiki/A-Podfile).
 
-    $ edit Podfile
-    platform :ios
-    dependency 'JSONKit',           '~> 1.4'
-    dependency 'Reachability',      '~> 2.0.4'
+```
+$ edit Podfile
+```
+
+```ruby
+platform :ios
+dependency 'JSONKit',           '~> 1.4'
+dependency 'Reachability',      '~> 2.0.4'
+```
 
 And then you [install the dependencies](https://github.com/CocoaPods/CocoaPods/wiki/Creating-a-project-that-uses-CocoaPods) in your project.
 
-    $ pod install App.xcodeproj
+```
+$ pod install App.xcodeproj
+```
 
 _Where ‘App.xcodeproj’ is the name of your actual application project._
 
 The next time you change your Podfile, you can update your project by simply running:
 
-    $ pod install
+```
+$ pod install
+```
 
 Remember to always open the Xcode workspace instead of the project file when you're building.
 
-    $ open App.xcworkspace
+```
+$ open App.xcworkspace
+```
 
 Sometimes CocoaPods doesn't have a Pod for one of your dependencies yet. Fortunately [creating a Pod](https://github.com/CocoaPods/CocoaPods/wiki/A-pod-specification) is really easy.
 
-    $ pod spec create Peanuts
-    $ edit Peanuts.podspec
-    $ pod spec lint Peanuts.podspec
+```
+$ pod spec create Peanuts
+$ edit Peanuts.podspec
+$ pod spec lint Peanuts.podspec
+```
 
 Once you've got it running [create a ticket](https://github.com/CocoaPods/CocoaPods/issues) and upload the Pod. If you're familiar with Git you can also fork the [CocoaPods specs](https://github.com/CocoaPods/Specs) repository and send a pull request. We really love contributions!
