 Take a closer look at [the full source code](https://github.com/ueberdosis/tiptap-next/tree/main/packages/extension-text-align) of the [`TextAlign`](/api/extensions/text-align) extension to see a more complex example. But here is how it works in a nutshell:
 
 ```js

 With the `renderHTML` function you can control how an extension is rendered to HTML. We pass an attributes object to it, with all local attributes, global attributes, and configured CSS classes. Here is an example from the `Bold` extension:
 
 ```js
-renderHTML({ attributes }) {
-  return ['strong', attributes, 0]
+renderHTML({ HTMLAttributes }) {
+  return ['strong', HTMLAttributes, 0]
 },

 The number zero (representing a hole) is used to indicate where the content should be inserted. Let’s look at the rendering of the `CodeBlock` extension with two nested tags:
 
 ```js
-renderHTML({ attributes }) {
-  return ['pre', ['code', attributes, 0]]
+renderHTML({ HTMLAttributes }) {
+  return ['pre', ['code', HTMLAttributes, 0]]
 },
 ```
 
 If you want to add some specific attributes there, import the `mergeAttributes` helper from `@tiptap/core`:
 
 ```js
-renderHTML({ attributes }) {
-  return ['a', mergeAttributes(attributes, { rel: this.options.rel }), 0]
+renderHTML({ HTMLAttributes }) {
+  return ['a', mergeAttributes(HTMLAttributes, { rel: this.options.rel }), 0]

 There is a whole lot to learn about node views, so head over to the [dedicated section in our guide about node views](/guide/advanced-node-views) for more information. If you’re looking for a real-world example, look at the source code of the [`TaskItem`](/api/nodes/task-item) node. This is using a node view to render the checkboxes.
 
 ## Start from scratch
-You can also build your own extensions from scratch with the `createNode()`, `createMark()`, and `createExtension()` functions. Pass an option with your code and configuration.
