 LuCI configuration lives in **Services->youtubeUnblock** section. It is self descriptive, with description for each flag. Note, that after you push `Save & Apply` button, the configuration is applied automatically and the service is restarted.
 
 UCI configuration is available in /etc/config/youtubeUnblock file, in section `youtubeUnblock.youtubeUnblock`. The configuration is done with [flags](#flags). Note, that names of flags are not the same: you should replace `-` with `_`, you shouldn't use leading `--` for flag. Also you will enable toggle flags (without parameters) with `1`.
