Since I originally wrote this post Ive re-written bits and included quick videos to guide you through the steps (My original post is still below).
As Im writing other posts on other topics related to Armbian, but not relevant to install/setup, Im keeping them all on my new site, so all my updates will be on there. Id welcome any feedback (drop me a comment on here or on https://www.OnDROID.net). Also, if anyone has any specific topics they want me to take a look at, let me know.
