+# Collaboration
+[![Version](https://img.shields.io/npm/v/@tiptap/extension-collaboration.svg?label=version)](https://www.npmjs.com/package/@tiptap/extension-collaboration)
+[![Downloads](https://img.shields.io/npm/dm/@tiptap/extension-collaboration.svg)](https://npmcharts.com/compare/@tiptap/extension-collaboration?minimal=true)
+
+The Collaboration extension enables you to collaborate with others in a single document. The implementation is based on [Y.js by Kevin Jahns](https://github.com/yjs/yjs), which is the coolest thing to [integrate collaborative editing](/guide/collaborative-editing) in your project.
+
+The history works totally different in a collaborative editing setup. If you undo a change, you don’t want to undo changes of other users. To handle that behaviour this extension provides an own `undo` and `redo` command. Don’t load the default [`History`](/api/extensions/history) extension together with the Collaboration extension to avoid conflicts.
