Write, version, and deploy with Jekyll
Use Markdown, deploy anywhere, and version with Git
Write docs in Markdown, not a CMS
Developers already write in Markdown. Jekyll lets your team contribute documentation using the same tools and workflows they use for code. No CMS login, no WYSIWYG editor, just clean Markdown files in a Git repo.
Version your docs alongside your code
Store documentation in the same repository as your source code. Branch, tag, and version your docs exactly like you version your software. Pull requests for docs get the same review process as code changes.
Deploy to GitHub Pages automatically
Push to main and your docs site updates automatically. No CI/CD pipeline to configure, no deployment scripts to maintain. GitHub Pages builds and deploys your Jekyll docs site on every push for free.

Our contributors submit docs changes as pull requests. It's the same workflow as our code. Brilliant.
We migrated 500 pages from Confluence to Jekyll. The site is faster and our docs are now in Git.
Jekyll docs themes gave us a professional docs site in a day. It would have taken weeks with a custom solution.
