Welcome aboard!
If you run into a problem, I suggest you note your experience level with Arch-based systems - as the answers you get will change emphasis with that knowledge. The might range from a step-by-step, to a link to a post that might help, or just a request for more info - or the results of running a terminal command (inxi -Fxxxz is common 
).
Enjoy - and the learning is relatively easy with a friendly bailout at you back…
