+Left 4 dead 2 server.
+
+# Ports
+- 27015
+- 27015/udp
+
+# Configuration
+
+The `server.cfg` gets created on the fly and gets filled with the enviroment variable starting with `CVAR_`. 
+So for example to set the RCON password set the enviroment variable `CVAR_RCON_PASSWORD=password123`. 
+Try to avoid variables with the word `CVAR_` and avoid `=` in it.
+
+A list of available cvars can be found [here](https://developer.valvesoftware.com/wiki/List_of_L4D2_Cvars).
