Absolutely, thanks a lot!
It's technically possible to install Arch without an internet connection by downloading the necessary packages from another computer, although since Arch is a rolling release distro you'll definitely want a consistent internet connection while using it. It can be a bit of a bother getting wifi set up at first, so if I'm working with a laptop I usually like to go through the install process with a wired connection and set up wifi afterwards, if that's possible for you.
I love Arch, at this point I couldn't imagine using a computer without it Let me know if you run into any trouble—I've installed and set it up lots of times on a variety of different machines so I can probably help. It goes pretty fast once you're used to it.
