Consider calling out the non-zero exit code explicitly (makes the CI behavior clearer).

Suggested change

	Validate your documentation build in strict mode, which exits with an error if there are any warnings or errors. Use this command for CI/CD pipelines to prevent broken documentation deployments.

Minor nit: using <groupname> matches the placeholder style used elsewhere on this page (and adding a period keeps the list consistent).

Suggested change

	- `--groups [groupname]`: Mock user groups for validation (useful when testing partial authentication)
	- `--groups <groupname>`: Simulate user groups during validation (useful when testing partial authentication).

	- `--disable-openapi`: Disable OpenAPI file generation during validation
