How to add existing block to additional pages?

I created an HTML block to use on my HOME page. Now I’d like to also add it to some other pages. I can’t figure out how and where to do that?

You need to create a new block on the ‘All pages’ tab using the same settings - you can then disable it on any pages you do not want it to appear. Make sure you disable or delete the original block or you will have 2 of the same blocks on the homepage.
