In ur server ftp you go to orangebox/cstrike/ there you find a lot of folders.
The main folders you will need are cfg (config), addons (you may still need to create this map) and maps (where the maps of your server, e.g. de_dust2 are located) Now in these main folders you will need to add stuff: in maps just custom maps you want to be on ur server, like wcs maps (search on fpsbanana). In addons you will have to extract latest eventscripts which you can google for. Next install all the files listed on the front page in WCS:OB latest build.

Now when all is added you must go to the cfg folder and in autoexec.cfg add following line:
es_xload wcs
then restart your server and wcs will work.

If you did it right like this little guide and the guide on front page tells you, wcs will fully work. If not, try to find which step you did wrong.

- How to view/edit the races/shopitems?
Look in the ini directory (Orangebox/cstrike/addons/eventscripts/wcs/ini)

- How to view/edit the ultimate code?
Look in the tools/ultimates/default directory (Orangebox/cstrike/addons/eventscripts/wcs/tools/ultimates/default)

- How to view/edit the abilitys code?
Look in the tools/abilitys directory (Orangebox/cstrike/addons/eventscripts/wcs/tools/abilitys/...)

To install standard admin,
here are some options:
1) In case you have sourcemod installed, using sourcemod admin is most secure.
look into addons/sourcemod/config/admin.cfg
(Note: all flags = z)
2) In case you do not have sourcemod installed, you can choose between:
A: mani_admin_plugin or B: XA (eXtensible Admin, included in EventScripts)
3) Look for another admin system yourself

Create a .txt file in the folder wcs/data/ called es_WCSadmins_db.txt
Now open the folder and write:
"WCSadmins"
{
"STEAM_X:X:XXXXXXX"
{
"wcsadmin" "1"
"wcsadmin_addadmins" "1"
"wcsadmin_removeadmins" "1"
"wcsadmin_editadmins" "1"
"wcsadmin_settings"             "1"
"wcsadmin_givexp"         "1"
"wcsadmin_givelevels" "1"
"wcsadmin_givecash" "1"
"wcsadmin_resetrace" "1"
"wcsadmin_resetplayer" "1"
}
}
This will give steamid STEAM_X:X:XXXXXXX full access to wcsadmin.

add to wcsadmin:
"WCSadmins"
{
"STEAM_X:X:XXXXXXX"
{
// WCSAdmin Flags
"wcsadmin" "1"
"wcsadmin_addadmins" "1"
"wcsadmin_removeadmins" "1"
"wcsadmin_editadmins" "1"
"wcsadmin_settings" "1"
"wcsadmin_givexp" "1"
"wcsadmin_givelevels" "1"
"wcsadmin_givecash" "1"
"wcsadmin_resetrace" "1"
"wcsadmin_resetplayer" "1"
// wcsCadmin Flags
"wcscadmin" "1"
"wcscadmin_give_self" "1"
"wcscadmin_give_players" "1"
"wcscadmin_give_cash" "1"
"wcscadmin_force_changerace" "1"
"wcscadmin_settings" "1"
"wcscadmin_players" "1"
"wcscadmin_admins" "1"
"wcscadmin_add_new_admin" "1"
"wcscadmin_update_admin" "1"
"wcscadmin_delete_admin" "1"
// LevelBank Admin Flags
                "wcsbankadmin"         "1"
}
}

1) Add metamod source in addons folder (do not forget to also add a metamod.vdf to make everything work)
2) Add sourcemod in addons folder
3) Add the sm effects plugin (.smx file) into addons/sourcemod/plugins
4) Restart server, done.

Add -debugto the startup line of your server (let your host do it in case you are not able to upload the startup line file to your web server).
That way you will receive a file called "console.log" in your cstrike folder.

WCS/config/config.cfg
In here you can configure xp ratings the way you like it.
// XP gained per kill
   wcs_cfg_killxp 30

// XP gained for a knife kill
   wcs_cfg_knifexp 40

// XP gained for making a headshot
   wcs_cfg_headshotxp 15

the only things you must make sure of is that:
- you use the correct race template (very sensitive, things like  "" [ ] and | as well).
- make sure you do not use the same race_aliases twice.
- don't use the same race twice.
