TL;DR Super easy to use standalone offline Arch Linux installer for Raspberry Pi which also configures your WiFi and other config on first boot.
Arch Linux and Raspberry Pi are made for each other. I run them together every where in my home. However, I have found the official installation instructions to be a bit cumbersome, especially if you are doing it often. So I made a GUI application where you just pick your SD card, and hit install. That’s it! It even allows you to configure your WiFi settings so your Pi will boot connected to your network and ready to be SSHed into.
