-Supported command line options:
+### General Options
 
-- `--help`: Print usage information.
+| Option          | Description                       |
-- `-D`, `--debug`: Enable shim debug logging (equivalent to `WIBO_DEBUG=1`).
+| --------------- | --------------------------------- |
-- `-C DIR`, `--chdir DIR`, `--chdir=DIR`: Change to `DIR` before running the guest program.
+| `-h, --help`    | Show usage information and exit   |
-- `--cmdline STRING`, `--cmdline=STRING`: Use `STRING` as the exact guest command line. (Including the program name as the first argument.)
+| `-V, --version` | Show version information and exit |
-- `--`: Stop option parsing; following arguments are interpreted as the exact guest command line. (Including the program name as the first argument.)
+
+### Runtime Options
+
+| Option             | Description                                                                                                      |

+| `-D, --debug`      | Enable debug logging (same as `WIBO_DEBUG=1`)                                                                    |
+| `--cmdline STRING` | Use `STRING` as the exact guest command line (must include the program name, e.g. `"test.exe a b c"`)            |
+| `--`               | Stop option parsing; following arguments are used verbatim as the guest command line, including the program name |
+
+### Subcommands
+
+| Subcommand | Description                                                                       |
+| ---------- | --------------------------------------------------------------------------------- |
+| `path`     | Convert between host and Windows-style paths (see `wibo path --help` for details) |
+
+### Examples
+
+#### Normal usage
+
+```sh
+wibo path/to/test.exe a b c
+wibo -C path/to test.exe a b c
+```
+
+#### Advanced: full control over the guest command line
+
+```sh
+wibo path/to/test.exe -- test.exe a b c
+wibo --cmdline 'test.exe a b c' path/to/test.exe
+wibo -- test.exe a b c
