+# Dockerized Bedrock Server
+This project is a simple dockerized environment in which to run a minecraft java vanilla server. The main goals vs existing solutions are simple persistence (bind mounts to easily modify+backup world and config data), keeping a slim image (alpine based, minimal layers), and easy iterability (change one URL to rebuild to build a new version or texture pack).
+
+The Docker Hub page can be found at [this link]([https://hub.docker.com/repository/docker/tarfeef101/mc_java_vanilla](https://hub.docker.com/repository/docker/tarfeef101/mc_java_vanilla)).

+```
+### config/
+This directory is what will be bind-mounted into the container to house your config files. You should put your personalized, `banned-ips.json`, `banned-players.json`, `ops.json`, `server.properties`, and `whitelist.json` files in this directory.
+
+### docker-compose.yaml
+This file is what defines the runtime state of your container. This is a very simple setup, so just ensure to  select whatever port you wish to expose for your host port, and remember to keep this project in a folder mounted on a drive where you want those persisted directories to store data.
+
+### Dockerfile
+The Dockerfile tries to keep the image as simple and slim as possible. A slim base image is used to reduce size, minimal packages are installed, and all `RUN` commands are kept into one layer to reduce size.
+
+### worlds/
+This is the bind-mounted directory which will house your world data. This should be empty unless you have a pre-existing world you want to import. If you want to add resource packs, this is the place to put them.
