You can costumize it :
"-console" – is for the ingame console (the one that opens with `)
"-game cstrike" – is for the counter strike game
"-secure" – is for your VAC anti cheat. If you want it disabled just type insecure instead of secure
"+maxplayers 22 – is the maximal number of slots on your server (you can change it)
"+map de_dust2 - the starting map (you can olso change it)
Patching the server
If you want your server to be Steam Only, skip this step !
Copy the content of css-dods folder (bin,steam,rev.ini) to SRCDS\css and overwrite the existig files.
Now we will make sure that you can administrate your server.
In order to do this you will have to install Source Metamod and Sourcemod or Mani Admin Plugin.
