+# Crons required for Comunic
+
+## Calls cron
+There is a cron to automatically cleanup old conversation. Ideally this cron should be executed every 30 seconds. The file to execute is `bin/clean_calls` 
 
 
-### Add API clients
 
+# Use calls in Comunic
+To use calls in Comunic, you need a WebRTCSignalExchangerServer, a small signal exchanging server written using NodeJS. You also need to modify your configuration file located at `config/overwrite.php` by copying and pasting commented configuration located at `config/calls.php` and make it fit your needs.
+
+
+# Add API clients
 In order to easily add clients to the API, a script has been created.

 Note : The name of the client must be unique, and the token should the strongest
