wcs .55 comes with the proper things needed, so no trouble.

4.Go to your /css/SERVER IP/cstrike/cfg/autoexec.cfg and add es_load WCS (if its not there)

Adding Custom Wcs Races
1. Go To /css/YOUR SERVER IP/cstrike/addons/evenscripts/wcs/WCSraces/es_WCSraces_db.txt and add your races there
2.To make sure all races work and dont crash your server, check the es_WCSraces_db.txt in the RaceFileChecker
3.Make sure all your races start from 1 then go to 2,3,4,5, etc
4.Make sure theres a { after the race number and a } after the race code.

Adding WCS Admins
1.Go to /css/SERVER IP/cstrike/addons/eventscripts/wcs/WCSadmin/es_WCSadmins_db.txt and add your wcs admins there like this:
                           "ADMIN STEAM ID"
{
    "name"              "ADMIN NAME"
    "give_xp_level"   "1"
    "give_money"     "1"
    "take_level"       "1"
    "reset_player"    "1"
    "script_settings" "1"
  }

Wcs Commands
Adding lvls- (NEED RCON OR FULL ADMIN)
1. type status in console, get their ID (infront of their steam) E.G.
---> THAT NUMBER (1625)# 1625 "(-Awper-) 2008" STEAM_0:1:14651814 06:40 183 0 active
and type rcon/ma_rcon wcs_givelevels <userid> <level amount>
E.G. rcon/ma_rcon wcs_givelevel 1625 5
gives 5 lvls to that person
2.or use wcs admin

Adding xp-(NEED RCON OR FULL ADMIN)
do the same thing for to give lvs but command is wcs_givexp

Adding private races
Go to your race folder and look for a race you like, then look for "allow_only" "0" on the race and add your steam ids instead of 0 like this
"allow_only" "<STEAM_X:XXXXXXXX><STEAM_X:XXXXXXXX><STEAM_X:XXXXXXXX><STEAM_X:XXXXXXXX>"
