 Please refer to documentation on our website. This includes schemas, quick-install 
 guides and how to use preconfigured packages and installers for all components.
 
+To install this agent on Mac OS X, you should execute pandora_agent_installer from
+command line and follow the instructions. The installer will place the correct files
+in /Library/StartupItems so the agent starts automatically upon startup. It is possible
+that Mac OS X complains after a reboot that the agent doesn't have the correct permissions.
+Allow the permissions to be fixed and then reboot again.
