 You can call `sofmani` with the following flags to alter the behavior for the current run:
 
-| Flag                | Description                        |
-| ------------------- | ---------------------------------- |

-| `-U`, `--no-update` | Disable update checking (default). |
-| `-h`, `--help`      | Display help information and exit. |

 Each of these flags overrides the loaded config file, so while your default config can choose not to
 check for updates by default, you or another user can add the `--update` flag to override this
