 ## Upgrading from 1.x to 2.x

 The new API will look pretty familiar too you, but there are a ton of changes though. To make the upgrade a little bit easier, here is everything you need to know:
 
 ### 1. Explicitly register the Document, Text and Paragraph extensions
 
-Tiptap 1 tried to hide a few required extensions from you with the default setting `useBuiltInExtensions: true`. Be sure to explicitly import the [Document](/api/extensions/document), [Paragraph](/api/extensions/paragraph) and [Text](/api/extensions/text) extensions.
+Tiptap 1 tried to hide a few required extensions from you with the default setting `useBuiltInExtensions: true`. That setting has been removed and you’re required to import all extensions. Be sure to explicitly import at least the [Document](/api/extensions/document), [Paragraph](/api/extensions/paragraph) and [Text](/api/extensions/text) extensions.

 ### 2. New document type
 **We renamed the default `Document` type from `doc` to `document`.** To keep it like that, use your own implementation of the `Document` node or migrate the stored JSON to use the new name.

 import Document from '@tiptap/extension-document'

 ### 3. New extension API

-In case you’ve built some custom extensions for your project, you’ll need to rewrite them to fit the new API. No worries, though, you can keep a lot of your work though. The schema, commands, keys, inputRules, pasteRules all work like they did before. It’s just different how you register them.
