After you save we'll do our best to look up the URL and expand it into an embed code for you. It's great for stuff like video embeds, audio embeds and code snippets and works for a variety of sites like YouTube, Vimeo, Soundcloud, GitHub Gists, Twitter, and Pastebin.
So insert a URL into your post like this:
And after you save you'll see the expanded version:
Try it out and let us know what you think.
