+## configuration
+
+configuration is entirely done inside the file `config.yml`.  
+you can specify the location of the config file with the optional argument `--config` or `-c` when starting the server.  
+otherwise the program will try to find a config file at the following locations:
+- `$HOME/.config/worklog/config.yml`
+- `$PWD/config.yml`
