 ### MDX Authoring
-If you add the MDX integration to your project, you can also write content using `.mdx` files, which let you include JavaScript expressions and custom components within your Markdown. This includes both static [Astro components](/en/basics/astro-components/) and interactive [framework components](/en/guides/framework-components/). Add UI elements such as a banner or an interactive carousel right in your text to turn your content into full-fledged web pages.

 Write blog posts in your existing Content Management System (CMS) such as Storyblok, WordPress, or Contentful. Some CMSes, like Storyblok, provide an official [Astro integration](https://www.storyblok.com/mp/announcing-storyblok-astro). Others expose a JavaScript SDK that Astro pages can use to [fetch your remote content](/en/guides/data-fetching/#fetch-from-a-headless-cms).

 ## Managing content pages
 
 Markdown and MDX files that live in your `src/pages` directory will automatically generate pages on your site using Astro's [file-based routing](/en/guides/routing/), built at a URL corresponding to the post's file path. 
 
 You can also choose to keep your Markdown and MDX files outside of the `src/pages` directory, and instead [import their content](/en/guides/markdown-content/#importing-markdown) into `.astro` pages.
 
+Astro's own [content collections](/en/guides/content-collections/) provide a powerful, type-safe way to work with your Markdown, MDX, or Markdoc content.
+
 If you're writing your content in a CMS, you can fetch your posts and use [dynamic routing](/en/guides/routing/#dynamic-routes) to use one `.astro` file to generate a route for each post. In Astro's default static mode, these routes are generated at build time. If you opt-in to [SSR mode](/en/guides/server-side-rendering/), you respond to a request at runtime and fetch the content on demand.
 
 ## Showcasing your content
 
-To build common features to organize and display your content, such as a blog archive or a page for each blog tag, Astro allows you to [fetch filenames and metadata](/en/reference/api-reference/#astroglob) from your Markdown and MDX frontmatter and use these to generate page content and routes.
