 # jilo
 
 JItsi Logs Observer
+
+Currently this has two components:
+
+- **jilo** is the script for collecting data from the logs.
+It is meant to be installed and run on the server and it needs read permissions for the logs.
+Currently it works with Videobridge and Jicofo log files.
+You can run it with cron to periodically update the new data from the logs.
+
+- **jilo-cli** is a command line client for displaying stats from an already populated jilo database
+It needs access to the jilo database.
+
+The database can be an SQLite file or MySQL/MariaDB database. The default is local sqlite file.
+
+The config file **jilo.conf** overrides the default settings.
+For more details check the comments in the scripts or use the --help option
