 ## Framework Tag
 
 The `src` attribute can be a relative path or a URL. The `type` attribute specifies the type of framework that corresponds to the `engine` supported. In this case type `podspec` means that the lib should be installed using the `cocoapods` package manager, and `nuspec` for the `nuget` package manager.
+
+## Spec Argument
+
+The `spec` arugment will specify the version of the CocoaPod that is to be used. `~>` is CocoaPod's optimistic operator-- copied from [CocoaPods docs](http://guides.cocoapods.org/using/the-podfile.html): 
+  - '~> 0.1.2' Version 0.1.2 and the versions up to 0.2, not including 0.2 and higher
+  - '~> 0.1' Version 0.1 and the versions up to 1.0, not including 1.0 and higher
+Cocoapods also support logical operators:
+  - '> 0.1' Any version higher than 0.1
+  - '>= 0.1' Version 0.1 and any higher version
+
+The string passed in the `spec` argument will be pasted into the Podfile.
