[CS:S] Slide/speedrun server

[MrTimcakes]

At the moment i run a CS:S Slide server however i would like to change it to a slide server (Like Gog #3 Gamers of Germany) With maps like Slide_shoxx_nitro However i have never found a tutorial on how to set one of these (When i try it in a listen server i can slide because it says some thing like "Restricted server only!" i want a server like this because i always get Stabbed on GOG #3 )
