Dark RP

Hi, I’ve recently started Gmod and found out about Dark RP i went on wikipedia got the link to Dark RP and downloaded it. (Didnt take that long either) It finishes and i go into game I click Create multiplayer, click on game mode and all i see is Sandbox and Fretta can someone help me on how to actually play Dark RP? Thanks for Spending your time on my Problems

You need to extract the DarkRP .zip file you downloaded into Steam/steamapps/username/garrysmod/garrysmod/gamemodes

Although DarkRP is no fun by yourself. Join a server that already has it installed, not only will there be a bunch of other people to play with, the server will download and install the gamemode for you.
