Just go to the grapheneOS website and it will walk you through it.
I have a medium competency with this kind of thing and the actual install was shockingly easy. Took about 15 mins.
You just change a couple of settings on your phone (it walks you through everything), plug it in and then press some buttons in sequence on their site.
Just make sure you back up everything you need from the phone first.
