Are you building on a WordPress.org based platform? If so, then https://indieweb.org/Getting_Started_on_WordPress may be what you want to start with. (I’ve written some of it, so let me know if there are particular pieces you’re having trouble with so we can improve them.)
I’ve got a handful of broad articles including a few that have full walk-through videos here: https://boffosocko.com/research/indieweb/
I’m sure some of the small pieces in the videos may have changed (improved) since I recorded them, but in general they should be helpful on process.
If you’ve got specific questions try asking in the IndieWeb chat: https://chat.indieweb.org/indieweb/ and we can help you out with the particulars.
