I want to make my Tumblr theme set up for a comic I'm making, so you can start at the beginning and click next, previous, first, last, ect. But I can't figure out how to do it. I know I need to be on the customization page, but then I need to turn on “Comic Pagination” and I don't know what that is or how to turn it on. Please help I just want to post my comic in a nice format.
