How do I enforce consistent Markdown formatting across my documentation?

You can enforce consistent Markdown formatting by validating files against a minimal default config or project-specific rules. This process detects non-compliant formatting and optionally auto-fixes common issues to maintain documentation readability.

Can I automatically fix Markdown style issues in READMEs and docs folders?

Yes, you can automatically fix Markdown style issues by running an optional auto-fix pass. This corrects common formatting deviations across workstreams like READMEs and docs folders while preserving readability and meeting style guidelines.

Does the Markdown validation process detect existing project configurations?

Yes, the Markdown validation process detects project-specific configurations to apply appropriate defaults. If a configuration is present, it validates files against those specific rules rather than relying solely on safe default settings.

Do I need to manually install markdownlint-cli before validating my files?
