Follow the red instructions so you aren't doing extra work where you don't need to!
NOTE: I have added notices before or during the parts where it is SRS specific, like making sure your skin is under 10MB (a limitation of the SRS Skin Transfer App used to automatically share custom skins just before races start).
I was going to make a post just linking the original tutorial, but after asking permission to the folks here at RD, it was suggested that I just post the tutorial in its entirety here! That said, let's get started! I was constructing it AS I was learning the process, so obviously some of this is going to be 'not the best way' to do certain things. This Tutorial was originally posted over on the forums where I do all of my skinning.
