+# Changelog
+
+The Mina Docs repository contains the source for the [Mina Docs](https://docs.minaprotocol.com/) website. 
+
+We publish product documentation using the same tools and processes as software code development, but docs are not bound by release cycles. 
+
+The published docs always contain the most up-to-date content available because doc changes are deployed to the live site immediately after a pull request (PR) is merged into the `main` branch. 
+
+Because docs are a high-visibility interface with our community and our users, we work hard to deliver content to help you discover, understand, and use the Mina Protocol and o1js. We are a small team working fast to keep up with the documentation demands of a continuously changing product. The documentation is open source and anyone can [contribute to the docs](https://github.com/o1-labs/docs2/blob/main/CONTRIBUTING.md).
