Forum:Can I add YouTube video to my page?

I recently just create a new page for a PBE RPG I am in, http://stexpanded.wikia.com/wiki/Star_Trek:_Washington, and a while back I created a recuitment video for the group and uploaded it to YouTube.

I was wondering if it was possible to link it up to my page, so people can watch it there. I remember seeing some button with YouTube on it, but I don't remeber where.
