 You can download the raw content of a snippet.
 
 By default snippets will be downloaded with Linux-style line endings (`LF`). If you want to preserve the original line endings you need to add a parameter `line_ending=raw` (eg. `https://gitlab.com/snippets/SNIPPET_ID/raw?line_ending=raw`). In case a snippet was created using the GitLab web interface the original line ending is Windows-like (`CRLF`).
+
+## Embedded Snippets
+
+> Introduced in GitLab 10.8.
+
+Public snippets can not only be shared, but also embedded on any website. This
+allows to reuse a GitLab snippet in multiple places and any change to the source
+is automatically reflected in the embedded snippet.
+
+To embed a snippet, first make sure that:
+
+- The project is public (if it's a project snippet)
+- The snippet is public
+- In **Project > Settings > Permissions**, the snippets permissions are
+  set to **Everyone with access**
+
+Once the above conditions are met, the "Embed" section will appear in your snippet
+where you can simply click on the "Copy to clipboard" button. This copies a one-line
+script that you can add to any website or blog post.
+
+Here's how an example code looks like:
+
+```html
+<script src="https://gitlab.com/namespace/project/snippets/SNIPPET_ID.js"></script>
+```
+
+Here's how an embedded snippet looks like:
+
+<script src="https://gitlab.com/gitlab-org/gitlab-ce/snippets/1717978.js"></script>
+
+Embedded snippets are displayed with a header that shows the file name if defined,
+the snippet size, a link to GitLab, and the actual snippet content. Actions in
+the header allow users to see the snippet in raw format and download it.
