 ```bash
-$ stackit config set --project-id xxxx-xxxx-xxxxx
+stackit config set --project-id xxxx-xxxx-xxxxx

 To remove it, you can run:
 
 ```bash
-$ stackit config unset --project-id
+stackit config unset --project-id
 ```
 
 Run the `config set` command with the flag `--help` to get a list of all of the available configuration options.
 
 You can lookup your current configuration by checking the configuration file or by running:
 
 ```bash
-$ stackit config list
+stackit config list
 ```
 
 You can also edit the configuration file manually.
