In that case, YunoHost + ## will automagically find a line with "KEY=VALUE" in FILENAME + ## (with the adequate separator between KEY and VALUE) + ## + ## YunoHost will then use this value for the read/get operation. + ## During write/set operations, YunoHost will overwrite the value + ## in **both** FILENAME and in the app's settings.yml + + ## Configuration file format supported: yaml, toml, json, ini, env, php, + ## python.
