+# What is Counter-Strike 2
+For over two decades, Counter-Strike has offered an elite competitive experience, one shaped by millions of players from across the globe. And now the next chapter in the CS story is about to begin. This is Counter-Strike 2. 
+This Docker image contains the dedicated server of the game.
+
+>  [CS2](https://store.steampowered.com/app/730/CounterStrike_2/)

+
+# How to use this image
+## Hosting a simple game server
+
+Running on the *host* interface (recommended):<br/>
+```console
+$ docker run -d --net=host --name=cs2 -e STEAMUSER={YOUR_STEAM_USER} -e STEAMPASS={YOUR_STEAM_PASSWD} joedwards32/cs2
+```
+
+Running using a bind mount for data persistence on container recreation:
+```console
+$ mkdir -p $(pwd)/cs2-data
+$ chmod 777 $(pwd)/cs2-data # Makes sure the directory is writeable by the unprivileged container user
+$ docker run -d --net=host -v $(pwd)/cs2-data:/home/steam/cs2-dedicated/ --name=cs2-dedicated -e STEAMUSER={YOUR_STEAM_USER} -e STEAMPASS={YOUR_STEAM_PASSWD} joedwards32/cs2
+```
+
+`STEAMUSER` and `STEAMPASS` **are required as unlike CS:GO, CS2 can not be downloaded anonymously (at time of writing).**
+
+**Steam Guard must be disabled on the Steam Account**
+
+**For security reasons, it is strongly recommended that you create a new Steam Account separate to your personal Steam Account.**
+
+**The container will automatically update the game on startup, so if there is a game update just restart the container.**
+
+# Configuration
+## Environment Variables
+Feel free to overwrite these environment variables, using -e (--env): 
+```dockerfile
+STEAMUSER="changeme"        (Steam User for SteamCMD. Steam Guard must be disabled.)
+STEAMPASS="changeme"        (Password for Steam User.)
+CS2_PORT=27015              (CS2 server listen port tcp_udp)
+CS2_RCONPW="changeme"       (RCON password)
+CS2_PW="changeme"           (CS2 server password)
+CS2_MAXPLAYERS=10           (Max players)
+CS2_GAMETYPE=0              (Game type, see)
+CS2_GAMEMODE=0              (Game mode, see)
+CS2_MAPGROUP="mg_active"    (Map pool)
+CS2_STARTMAP="de_inferno"   (Start map)
+CS2_ADDITIONAL_ARGS=""      (Optional additional arguments to pass into cs2)
+```
