Embed YouTube videos

[YouTube dQw4w9WgXcQ]

Note dQw4w9WgXcQ is the id of the video, which can be found on the YouTube video URL.

Comments

You can add markdown code comments that won't be rendered on your note like this:

[//]: # (This may be the most platform independent comment)

Additional considerations

• Newlines are supported (Markdown doesn't by default).
• If you add a link URL we automatically auto-link to it. No need to wrap in the text syntax.
• Images uploaded are downsized automatically.
• We escape any HTML on the Markdown note. This is to avoid things like XSS.
