Thanks for your answer
Most of it came from this one: http://devtome.com/doku.php?id=scrypt_altcoin_cloning_guide
It is, however, not complete, nor up-to-date, so i'm afraid you'll have to use all of them, and even use google to find answers to some problems you'll inevitably face when you want to create an altcoin...
If i remember correctly, the problems started in step 1: the coin they cloned from github: the repo was no longer there, so i cloned SmallChange instead... the whole process went smooth, but you actually have to think with every step in the process, and solve the problems you face by using google or the other links i gave you...
Good luck!
