 # Creating and invoking OpenWhisk actions
 
 
-Actions are stateless code snippets that run on the OpenWhisk platform. An action can be written as a JavaScript, Swift, or Python function, a Java method, or a custom executable program packaged in a Docker container. For example, an action can be used to detect the faces in an image, respond to a database change, aggregate a set of API calls, or post a Tweet.

+An action can be written as a JavaScript, Swift, Python or PHP function, a Java method,
+any binary-compatible executable including Go programs and custom executables packaged as Docker containers.
 
-Actions can be explicitly invoked, or run in response to an event. In either case, each run of an action results in an activation record that is identified by a unique activation ID. The input to an action and the result of an action are a dictionary of key-value pairs, where the key is a string and the value a valid JSON value. Actions can also be composed of calls to other actions or a defined sequence of actions.

 Review comment:
   Note: This isn't new text - i just reformatted the text that was there. No semantic change.
   
   JSON is a representation of a dictionary native to JS. In Swift and Python we use a dictionary type that is native to those languages.
