+### Generating unique request ids
+
+The agent generates unique request ids for all request handled. It
+will use [uuid4r](https://github.com/skaes/uuid4r) if this is
+avalaibale in the application. Otherwise it will fall back to use the
+standard `SecureRandom` class shipped with Ruby.
+
+### Generating JSON
+
+The agent will try to use the [Oj](https://github.com/ohler55/oj) to
+generate JSON. If this is not available in your application, it will
+fall back to the `to_json` method.
 
 ## Troubleshooting
 
 If the agent experiences problems when sending data, it will log information to a file named
 `logjam_agent_error.log` which you can find under `Rails.root/log`.
