Do a search F**k

If you need to ask forget it.

just do a search. i didnt know much about it but did some research hand found out how to mostly do it. it is hard and alot of work needs to be done, not to mention the engineers cert to make it legal. but if you do all your own searching and find people that have already done it that it will be easyer to understand and then ask the questions of the stuff you didnt understand.
