Before you post, please make sure to:
Check other posts. - A lot of times someone has had the exact same issue as you do.
Search other forums. - Because we're based on Arch Linux, a lot of their how-tos are directly applicable to Arch Linux ARM. https://wiki.archlinux.org/index.php/Main_Page and https://bbs.archlinux.org/
Google your error. - Once again, someone has probably come across the same problem as you have. A lot of the time, I answer someone's question directly from a Google search.
