+OLMKit
+======
+
+OLMKit exposes an Objective-C wrapper to libolm.
+
+The original work by Chris Ballinger can be found at https://github.com/chrisballinger/OLMKit.
+
+Installation
+------------
+You can embed OLMKit to your application project with CocoaPods. The pod for
+the latest OLMKit release is::
+
+ pod 'OLMKit'
+
+Development
+-----------
+Run `pod install` and open `OLMKit.xcworkspace`.
+
+The project contains only tests files. The libolm and the Objective-C wrapper source files are loaded via the OLMKit CocoaPods pod.
+
+To add a new source file, add it to the file system and run `pod update` to make CocoaPods insert it into OLMKit.xcworkspace.
+
+Release
+-------
+See ../README.rst for the release of the CocoaPod.
+
