+## Docker
+
+### Example
+
+To host an Arma 3 x64 server with an existing Arma 3 Server install in subfolder `arma3` with persisted profiles in `profiles` and shared network with host,
+
+```sh
+mkdir -p arma3 profiles
+touch servers.json
+docker run \
+  --network=host \
+  --env GAME_TYPE=arma3_x64 \
+  --env GAME_PATH=/arma3 \
+  --volume $PWD/arma3:/arma3 \
+  --volume $PWD/servers.json:/app/servers.json \
+  --volume $PWD/profiles:"/root/.local/share/Arma 3 - Other Profiles" \
+  dahlgren/arma-server-web-admin
+```
+
+### Required setup
+
+Mount a preinstalled Arma server folder to the container, currently only the linux server is supported.
+Set GAME_TYPE to your desired arma server, for example `--env GAME_TYPE=arma3` or `--env GAME_TYPE=arma3_x64`.
+Set GAME_PATH to your mounted volume, for example `--env GAME_PATH=/arma3` and `--volume $PWD/arma3:/arma3`.
+
+### Networking
+Host preferably needs to share network with the container or all game ports used will need to be forwarded to the container.
+Use `--network=host` to use same network as the host machine.
+
+Web Admin UI is available at port 3000.
+If you use `--network=host` you can reach the web ui at `http://localhost:3000` by default.
+
+### Persistence
+
+#### Servers
+
+Mount a file at `/app/servers.json` to persist the servers config.
+For example `--volume $PWD/servers.json:/app/servers.json` to use a file named `servers.json` in current folder as persistent servers config file.
+
+#### Profiles
+
+If you need to persist the server profiles such as vars file make sure to mount a volume.
+For Arma 3 the default profiles directory will be located at `/root/.local/share/Arma 3 - Other Profiles`
+
+### Environment Variables
+
+Key | Description
+--- | ---
+GAME_PATH | Required. Absolute folder path to game server in docker container
+GAME_TYPE | Required. Type of game server, see above
+AUTH_USERNAME | Username used for HTTP Basic Auth
+AUTH_PASSWORD | Password used for HTTP Basic Auth
+SERVER_ADMINS | Steam IDs that should be set as admins
+SERVER_ADDITIONAL_CONFIG | Additional content to add into server.cfg
+SERVER_MODS | Mods to be loaded as server side only mods
+SERVER_PARAMETERS | Additional parameters to pass on server launch
+SERVER_PREFIX | Prefix on all server names
+SERVER_SUFFIX | Suffix on all server names
