-# Environment Variables
-
-The environment variables reflect the command-line options. If both a command-line option and an environment variable
-is present, the flag takes priority over the environment variable.
-
-All variables follow the format `SW_<option>`, i.e. the flag `--log-level`, becomes `SW_LOG_LEVEL`.
-
-The variables need to be defined before starting the app, for example:
-
-    SW_LOG_LEVEL=debug ./soundwerft
-
-## Define in env-file
-Instead of defining each variable as an environment variable, an env-file can be used, in which all variables are defined.
-
-If a filed called `.env` is present in the current working directory, it will automatically be used. 
-Otherwise, the file can be specified by starting the app with `--config / -c` option.
