How to embed a youtube video onto an article on the main page?

OK, got it to work, I needed to click on <> in the menu bar to choose HTML article. I place it in the center block.  I added the video of Lauren reading a Haunted House, a poem I wrote while viewing my haunted village.
There's Shadow the Ghost in a right block as a chatter bot that you can talk with, after I add the Haunted theme by Stormy, I think I am going to have a most original site and forum.
