 ## Usage
-To use the CLI, the `init` command must be called once,
-with the `--controller` parameter specifying the target goSDN controller.
-This value is persisted for all following commands and can be changed by calling `init` again.
-If the parameter is not specified, the default `gosdn-develop.apps.ocp.fbi.h-da.de:55055` will be used.
+
+To use the CLI, the `login` command must be called, with the `--controller` parameter specifying the target goSDN controller (\<IP:Port\>) and providing correct credentials.
+The set controller address and recieved access token will be persisted for all following commands and can be changed by calling `login` again. If the `--controller` parameter is not specified, the default set in gosdnc.toml (`gosdn-develop.apps.ocp.fbi.h-da.de:55055`) will be used.
 
 Command help is available via the --help flag for each command, or via the `gosdnc help` command.
