+Point-Free’s The Composable Architecture uses Apple's Combine framework as the basis of its Effect type. Unfortunately, Combine is only available on iOS 13 and macOS 10.15 and above. In order to be able to use it with earlier versions of the OSes, this fork has adapted The Composable Architecture to use RxSwift as the basis for the Effect type. Much of this work was also inspired by the wonderful ReactiveSwift port of this project as well.

       - If you have a single application target that needs access to the library, then add **ComposableArchitecture** directly to your application.
       - If you want to use this library from multiple targets you must create a shared framework that depends on **ComposableArchitecture** and then depend on that framework in all of your targets. For an example of this, check out the [Tic-Tac-Toe](./Examples/TicTacToe) demo application, which splits lots of features into modules and consumes the static library in this fashion using the **TicTacToeCommon** framework.
 
+### Cocoapods
+
+You will need to add this to your Podfile:
+```
+pod 'ComposableArchitecture', :git => 'git@github.com:dannyhertz/rxswift-composable-architecture.git'
+```
