There are no new options and no changes to how you author code blocks and syntax highlighting.
**Potentially breaking change:** While this refactor should be transparent for most projects, the transition to `shikiji` now produces a smaller HTML markup by attaching a fallback `color` style to the `pre` or `code` element, instead of to the line `span` directly. For example:
This does not affect the colors as the `span` will inherit the `color` from the parent, but if you're relying on a specific HTML markup, please check your site carefully after upgrading to verify the styles.

This lets you import Astro components directly to render as Markdoc tags and nodes, without the need for the previous `components` property. This new configuration also unlocks passing variables to your Markdoc from the `Content` component ([see the new docs](https://docs.astro.build/en/guides/integrations-guide/markdoc/#pass-markdoc-variables)).
## Migration
Move any existing Markdoc config from your `astro.config` to a new `markdoc.config.mjs` file at the root of your project. This should be applied as a default export, with the optional `defineMarkdocConfig()` helper for autocomplete in your editor.
This example configures an `aside` Markdoc tag. Note that components should be imported and applied to the `render` attribute _directly,_ instead of passing the name as a string:
```js
// markdoc.config.mjs
import { defineMarkdocConfig } from '@astrojs/markdoc/config';
import Aside from './src/components/Aside.astro';
export default defineMarkdocConfig({
tags: {
aside: {
render: Aside,
},
},
});
```
You should also remove the `components` prop from your `Content` components. Since components are imported into your config directly, this is no longer needed.

This unlocks Markdoc inside your Content Collections, bringing support for Astro and UI components in your content. This also improves Astro core internals to make Content Collections extensible to more file types in the future.
You can install this integration using the `astro add` command:
```
astro add markdoc
```
