 <!-- USAGE EXAMPLES -->
 ## Usage
 
-Right now it is sufficient to run the executable, or start the container.
+To start the server it is simply a matter of running the executable.
+By default, it looks for a configuration file in the same directory, however it can be changed with the `-c` or `--config_path` optional parameter.
 
-Please note that currently the server does not relay the data to anything else except Growatt's servers on `server.growatt.com`.
+Please take a look at the default [configuration file for more information](config.yaml). (Soon they will be listed here too)
+
+If a log level different from `INFO` is necessary, set the environment variable `LOG_LEVEL` to the required level (`DEBUG`, `TRACE`, etc.)
+
+The server will relay data to the endpoint specified in the configuration file.
+It defaults to Growatt's servers on `server.growatt.com`.
+
+For more command-line options, use the `--help` option.
