+# Multicraft Jar Configurations
+
+This repository contains the Multicraft jar configuration files that are used in conjunction with the [java-multi-version](https://git.jrdn.dev/jordanwalster/-/packages/container/java-multi-version/latest) docker image. 
+
+This allows Multicraft to utilise the built in docker feature whilst maintaining the ability to run different versions of Minecraft, since the `multicraft.conf` forces the selection of a single jdk image.
+
+## How to use
+
+The configurations from this repo can be used with a bare metal installation of Multicraft, but my preferred method is using Docker-in-Docker, allowing the entire minecraft stack to be containerised.
+
+1. Grab your key from Multicraft and store it in the root directory.
+
+2. Run Multicraft using the [multicraft-docker](https://git.jrdn.dev/jordanwalster/-/packages/container/multicraft-docker/latest) image and the accompanying `docker-compose.yml` & `.env` files.
+
+3. Navigate to the `install.php` file and complete the setup matching the values to the `.env` file.  
+
+4. Once setup is complete, navigate to Settings > Update Minecraft > Add or Remove Files
+    - In the JAR Filename, File URL and Conf URL fields, enter the chosen file: e.g.
+      - JAR Filename: `paper-1.21.4.jar`
+      - File URL: `https://mc-assets.jrdn.dev/jar/paper-1.21.4.jar`
+      - Conf URL: `https://mc-assets.jrdn.dev/conf/paper-1.21.4.jar.conf`
+
+All configuration files are in the <strong>/conf</strong> path, matching their corresponding `.jar` files in <strong>/jar</strong>, with the same name plus a `.conf` extension.
