 ## Features
 * **streams**: multiple random music streams when no program is played. We also can specify a time range and frequency for each;
 * **diffusions**: generate diffusions time slot for programs that have schedule informations. Check for conflicts and rerun.
 * **liquidsoap**: create a configuration to use liquidsoap as a stream generator. Also provides interface and control to it;
-* **sounds**: each programs have a folder where sounds can be put, that will be detected by the system. Quality can be check and reported for later use. Later, we plan to have uploaders to external plateforms. Sounds can be defined as excerpts or as archives.
-* **cms**: application that can be used as basis for website;
+* **sounds**: each programs have a folder for its podcast. Aircox detects updates, can run quality check, import related playlist (timestamped or position in track list). Sounds can be defined as excerpts or as archives.
 * **log**: keep a trace of every played/loaded sounds on the stream generator.
+* **admin**: admin user interface.
+* **cms**: content management system.
