Updating DarkRP to my own version

[Sambolinski]

Hey Im sambolinski or Simon fish (HRP)

Im making my own version of a DarkRP gamemode. I call it WarOfTheWorldsRP al you can tell by the name it's to do with the book War of the worlds. Can I get any advice from people who have manipulated DarkRP for their own gamemode. I guess like HRP.
 Thanks for any advise
