 # SteamCMD in Docker optimized for Unraid
-This Docker will download and install SteamCMD. It will also install ARK:SurvivalAscended and run it (Normal server startup of ARK can take a long time!).
+This Docker will download and install SteamCMD and the according game that is pulled via specifying the Tag.
 
-**WARNING:** You have to set the value vm.max_map_count to at least 256000 on the host as root with the command:  
-`echo 265000 > /proc/sys/vm/max_map_count`  
-To make that value persistent on Unraid please use a User Script that runs on startup or with the command from above or put it in your `go` file.
-
-ATTENTION: First Startup can take very long since it downloads the gameserver files!
-
-Update Notice: Simply restart the container if a newer version of the game is available.
-
-You can also run multiple servers with only one SteamCMD directory!
+**Please see the different Tags/Branches which games are available.**
 
 ## Example Env params for CS:Source
 | Name | Value | Example |
 | --- | --- | --- |
 | STEAMCMD_DIR | Folder for SteamCMD | /serverdata/steamcmd |
 | SERVER_DIR | Folder for gamefile | /serverdata/serverfiles |
-| GAME_ID | The GAME_ID that the container downloads at startup. If you want to install a static or beta version of the game change the value to: '2430930 -beta YOURBRANCH' (without quotes, replace YOURBRANCH with the branch or version you want to install). | 2430930 |
-| MAP | Enter your preferred map name | TheIsland_WP |
-| SERVER_NAME | Your server name goes here | ASA Docker |
-| SRV_PWD | Your server password goes here | Docker |
-| SRV_ADMIN_PWD | Your server admin password goes here | adminDocker |
-| GAME_PARAMS | Enter your game parameters seperated with ? and start with a ? | ?Port=7777?MaxPlayers=20 |
-| GAME_PARAMS_EXTRA | Enter your Extra Game Parameters seperated with a space and - | -server -log -NoBattlEye |
+| GAME_ID | The GAME_ID that the container downloads at startup. If you want to install a static or beta version of the game change the value to: '232330 -beta YOURBRANCH' (without quotes, replace YOURBRANCH with the branch or version you want to install). | 232330 |
+| GAME_NAME | SRCDS gamename | cstrike |
+| GAME_PARAMS | Values to start the server | -secure +maxplayers 32 +map de_dust2 |
 | UID | User Identifier | 99 |
 | GID | Group Identifier | 100 |
+| GAME_PORT | Port the server will be running on | 27015 |
 | VALIDATE | Validates the game data | blank |
 | USERNAME | Leave blank for anonymous login | blank |
 | PASSWRD | Leave blank for anonymous login | blank |
