+## Previewing as a specific group
+
+If you use partial authentication to restrict access to your documentation, you can preview as a specific authentication group by using the `--group [groupname]` flag.
+
+For example, if you have a group named `admin`, you can preview as a member of that group with the command:
+
+```bash
+mint dev --group admin
+```
+
 ## Additional commands
 
 While `mint dev` is the most commonly used command, there are other commands you can use to manage your documentation.
