 # Add Netlify CMS to Your Site
 
 Netlify CMS is adaptable to a wide variety of projects. The only inflexible requirement is that your site content must be written in markdown, JSON, YAML, or TOML files, stored in a repo on [GitHub](https://github.com/). (If you're partial to another Git hosting service, check out the PRs in progress for [GitLab](https://github.com/netlify/netlify-cms/pull/517) and [Bitbucket](https://github.com/netlify/netlify-cms/pull/525) support.)

 # Beta Features!
 We run new functionality in an open beta format from time to time. That means that this functionality is totally available for use, and we _think_ it might be ready for primetime, but it could break or change without notice.
