# @blocknote/core/y

This package contains integrations for Yjs (v14) with BlockNote (based on `@y/y` & `@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 v13, you can use the `@blocknote/core/yjs` package instead which will use the `yjs` & `y-prosemirror` packages.
