+# Better than Adventure! Docker
+This is a fairly simple Docker container used to run a Minecraft server with the [Better than Adventure!](https://www.betterthanadventure.net/) modpack.
+
+Better than Adventure! is an unofficial fork of Minecraft Beta 1.7.3, a version of the game released in 2011. Its goal is to revitalize classic Minecraft with new gameplay features, quality of life improvements, and optimizations!
+
+## Usage
+The user is assumed to have already got a basic Docker instalation up and running. If you haven't, go do that and come back when you're finished.
+
+#### Basic Usage
+
+please note that for now fzorb/betterthanadventure is a placeholder
+```bash
+# Most basic server. Uses default environment variables
+$ docker run -p 25565:25565 fzorb/betterthanadventure
+# Change the version & maximum amount of ram the server uses:
+$ docker run -p 25565:25565 -e XMX=2G -e VERSION=7.1-prerelease-1 fzorb/betterthanadventure
+# Mount the server files to a different directory
+$ docker run -p 25565:25565 -e XMX=2G -v /srv/bta:/srv/bta fzorb/betterthanadventure
+```
+#### Using this container with `docker-compose`
+Example `docker-compose.yml` file:
+```yml
+services:
+  betterthanadventure:
+    image: fzorb/betterthanadventure
+    container_name: btaServer
+    ports:
+      - "25565:25565"
+    environment:
+      - XMX=2G
+      - VERSION=7.2_01
+    volumes:
+      - /srv/bta:/srv/bta
+    restart: unless-stopped
+```
+
+## Environment Variables
+The container has two environment variables:
+* **VERSION**: The version of Better than Adventure! you want to run. Defaults to `7.2_01`. You can get the version from [here](https://github.com/Better-than-Adventure/bta-download-repo/releases) (make sure to remove the v in front of the version)
+* **XMX**: Maximum ammount of ram the server can use. Defaults to `2G`.
+
+## Technical
+This project does not redistribute in any way, shape or form the Better than Adventure! modpack. The modpack's files are downloaded via the `bta.sh` script. 
+
+**PLEASE NOTE**: This project is not in any way, shape or form affiliated with the Better than Adventure! project. This is an unofficial Docker container.
