Sorry, but installing arch linux doesn't mean you are some computer master. You are just following instruction on a wiki. Anyone could install arch linux if felt like, and wanted to put some time into it.
Some people make arch linux their personality especially the forum.
You can just ask questions here, people actually gave me tips to configure/manage Nvidia PRIME on Arch before it was officially supported on the proprietary blobs on the megathread, of all places :)
People here are cool. If I know something I answer and if I ask someone answers helpfully. Comrades helping comrades.
