I have to say, it was a scary thing to do. Specially if you lack any and all experience such as I did, However, it's all a matter of doing it with care. Good luck my friend let me know how it turns out.
No there is no guide, I did it all risking the card and learning along the way. You would however, read on a previous comment were I explained to someone else how to do this. If you have any questions let me know.
