## General Help Page
## Optional Built-in Command Entries
In order to support using the `-h` option to list the commands available to the application, just register a new command as such:
Clipanion offers common optional command entries out-of-the-box, under the `Command.Entries` namespace.
They have to be manually registered:
```ts
class HelpCommand extends Command {
@Command.Path(`--help`)
@Command.Path(`-h`)
async execute() {
this.context.stdout.write(this.cli.usage(null));
}
}
cli.register(Command.Entries.Help);
cli.register(Command.Entries.Version);
```
This will print a block similar to the following:
### Help Command - General Help Page
> Paths: `-h`, `--help`
The `Command.Entries.Help` command displays the list of commands available to the application, printing a block similar to the following.
![](assets/example-general-help.png)
### Version Command
> Paths: `-v`, `--version`
The `Command.Entries.Version` command displays the version of the binary provided under `binaryVersion` when creating the CLI.
