HOW TO ADD A YOUTUBE VIDEO!!!

ok so using the FAQ of friend project is ok, but some stuff isnt super clear!
this is the code that I adapted to fit better on my page, bc its normally really big-
<object width="435" height="216" type="text/html" allowscriptaccess="always" allowfullscreen="true" data="[INSERT EMBED LINK HERE]?&autoplay=1"> </object>

to get the embed link, go to youtube, then hit share on the video, then embed, and copy just the https link. ill provide a ss to show u what i mean! just copy whats inside the "" between = and frameboarder
