+## Configuration
+
+The main configuration file is the `env` file located in `config/`. There's an example file called `env.example` which you
+need to copy to `config/env`. 
+
+**Information for docker users**: it's possible to have the `env` file persistent and not within the container so 
+that rebuilding the image isn't required. Create a host volume `/path/from/host/env` and map it to 
+`/var/www/html/application/config/env`. Changes will show up after restarting the container.

-* Build the docker image from the project home with `docker build -t ts3web:latest -f docker/Dockerfile .`
-* Create a container with the image. Make sure that if teamspeak and ts3web share the same docker instance they should be put into one network and the subnet should be added to teamspeak's query whitelist. The web interface won't work otherwise.

 * Change directory to `docker-compose/` folder
 * Execute `docker-compose up -d`
