The `RichText` component can be considered as a super-powered `textarea` element, enabling rich content editing including bold, italics, hyperlinks, etc. It is not too much unlike the single editor region of the legacy post editor, and is in fact powered by the same TinyMCE library.

To use the `RichText` component, add `wp-editor` to the array of registered script handles when calling `wp_register_script`.

It would be awesome to get a code example here, if possible (presumably just taking the example from the first page in the tutorial and updating it)

@greenhornet79 Could you put this code sample below the "To use the RichText component" sentence so it's a little clearer what the code sample is explaining?

I think also instead of the entire block registration function, it would be easier to just show the wp_register_script segment, calling out the change:

wp_register_script(
	'gutenberg-boilerplate-es5-step03',
	plugins_url( 'step-03/block.js', __FILE__ ),
	array(
		'wp-blocks',
		'wp-element'
		'wp-editor', // Note the addition of wp-editor to the dependencies
	)
);


```php
wp_register_script(
'gutenberg-boilerplate-es5-step03',
plugins_url( 'step-03/block.js', __FILE__ ),
array(
'wp-blocks',
'wp-element',
'wp-editor', // Note the addition of wp-editor to the dependencies
)
);
```

Implementing this behavior as a component enables you as the block implementer to be much more granular about editable fields. Your block may not need `RichText` at all, or it may need many independent `RichText` elements, each operating on a subset of the overall block state.

Because `RichText` allows for nested nodes, you'll most often use it in conjunction with the `html` attribute source when extracting the value from saved content. You'll also use `RichText.Content` in the `save` function to output RichText values.
