 ## Configuration
 Ytcc searches for a configuration file at following locations:
 
-1. `$XDG_CONFIG_HOME/ytcc/ytcc.conf`
-2. `~/.config/ytcc/ytcc.conf`
-3. `~/.ytcc.conf`

+4. `/etc/ytcc/ytcc.conf`
 
-If no config file is found in these three locations, a default config file is created at `~/.config/ytcc/ytcc.conf`.
