The arch install guide is pretty good. The only tricky part is the bootloader install, if you don't get that right the system won't boot. Also you probably want to disable secure boot in the uefi bios on your system. https://wiki.archlinux.org/title/Arch_boot_process#Boot_loader
One thing to keep in mind. If you do install the system successfully, when it boots you just get a command prompt. Arch doesn't make any choices for you. You have to install your choice of GUI and useland tools on your own.
