This is an example page with an embedded YouTube video.
To embed the video, use an include where you want the video to appear and then pass in the YouTube id as the video variable.
{% include youtube.html video="videoid" %}
You can optionally include a start time in seconds. This works the same as the ?t= parameter in Youtube URLs.
{% include youtube.html video="videoid" time=210 %}
It is also possible to embed Vimeo videos in a similar way
{% include vimeo.html video="videoid" %}
