+
+When specifying commands with `command: Commands`, they are required.
+Alternatively, you could do `command: Option<Commands>` to make it optional.
+```console
+$ 03_04_subcommands_derive
+? failed
+A simple to use, efficient, and full-featured Command Line Argument Parser
+
+Usage: 03_04_subcommands_derive[EXE] <COMMAND>
+
+Commands:
+  add   Adds files to myapp

+
+Options:
+  -h, --help     Print help
+  -V, --version  Print version
+
+```
+
+Since we specified [`#[command(propagate_version = true)]`][crate::Command::propagate_version],
+the `--version` flag is available in all subcommands:
+```console
+$ 03_04_subcommands_derive --version
+clap [..]
+
+$ 03_04_subcommands_derive add --version
+clap-add [..]
+
+```
