 CryptoSwift
 ===========
 
-Bunch of crypto related functions for Swift
+Crypto related helpers for Swift.
+
+Requirements
+============
+For now CryptoSwift depends on OpenSSL
+
+Usage
+=====
+
+Use cocoapods, add this to Podfile
+
+`pod 'CryptoSwift', :git => 'https://github.com/krzyzanowskim/CryptoSwift.git', :branch => :master`
