+# mc-server-packwiz-docker
+
+If you like Docker and keeping all your Minecraft Java server mods in one place using [packwiz](https://packwiz.infra.link/), as well as keeping track of all changes with Git, then this template repository is for you!
+
+It comes with:
+
+- a sample packwiz modpack
+- a lightweight HTTP server image based on [BusyBox](https://hub.docker.com/_/busybox) that's used with [`packwiz-installer`](https://packwiz.infra.link/tutorials/installing/packwiz-installer) by [Minecraft Server on Docker](https://docker-minecraft-server.readthedocs.io/en/latest)
+- a setup script, which not only lets you reinitialise the modpack, but also generates a minimal `.env` file for the Minecraft Server along with Git hooks for automatically refreshing the modpack's index (while also preventing files in `.dockerignore` from getting listed)
+
+## Initial setup
+
+> [!WARNING]  
+> Make sure to audit the contents of `setup.sh` before running it!
+> If you've noticed potentially malicious code, notify me immediately [via email](mailto:contact@maciejpedzi.ch).
+
+```sh
+git clone https://github.com/maciejpedzich/mc-server-packwiz-docker
+cd mc-server-packwiz-docker
+sudo chmod +x setup.sh
+./setup.sh
+```
+
+## Launching the Minecraft server
+
+```sh
+sudo docker compose build
+sudo docker compose up -d
+```
