# @blocknote/core/yjs

This package contains integrations for Yjs (v13) with BlockNote (based on `yjs` & `y-prosemirror`). Given that we are going to support both Yjs v13 & v14, we need to have a way to support both versions independently.

If you want to use Yjs v14, you can use the `@blocknote/core/y` package instead which will use the `@y/y` & `@y/prosemirror` packages.
