 ## Introduction
 Real-time collaboration, syncing between different devices and working offline used to be hard. We provide everything you need to keep everything in sync, conflict-free with the power of [Y.js](https://github.com/yjs/yjs). The following guide explains all things to take into account when you consider to make tiptap collaborative. Don’t worry, a production-grade setup doesn’t require much code.
 
-## Configure collaboration
+## Configure the editor
 The underyling schema tiptap uses is an excellent foundation to sync documents. With the [`Collaboration`](/api/extensions/collaboration) you can tell tiptap to track changes to the document with [Y.js](https://github.com/yjs/yjs).
 
 Y.js is a conflict-free replicated data types implementation, or in other words: It’s reaaally good in merging changes. And to achieve that, changes don’t have to come in order. It’s totally fine to change a document while being offline and merge the it with other changes when the device is online again.

 Yes, it’s magic. As already mentioned, that is all based on the fantastic Y.js framework. And if you’re using it, or our integration, you should definitely [sponsor Kevin Jahns on GitHub](https://github.com/dmonad), he is the brain behind Y.js.

 The document name is `'example-document'` in all examples here, but it could be any string. In a real-world app you’d probably add the name of your entity and the ID of the entity. Here is how that could look like:
