+# Blast Furnace Extended Datapack
+
+This minor QoL datapack extends the functionality of the Blast Furnace by adding all possible smelting recipes (recipes that aren't in the Smoker) to it.
+
+## How to Update This Datapack for a New Minecraft Version
+
+This datapack can be automatically updated to include all the latest recipes from any new version of Minecraft.
+
+### Prerequisites
+
+*   You must have Python 3 installed on your system.
+*   You need to download the official Minecraft Server `.jar` file for the version you want to support.
+
+### Update Steps
+
+1.  **Download the Minecraft Server `.jar`**
+    *   You can find the official server file on the [Minecraft website](https://www.minecraft.net/en-us/download/server).
+    *   Once downloaded, place the file in this directory and rename it to `server.jar`.
+
+2.  **Run the Generation Script**
+    *   Open a terminal or command prompt in this directory.
+    *   Run the Python script with the following command:
+        ```bash
+        python generate_recipes.py
+        ```
+    *   The script will automatically:
+        *   Delete any old recipes in the `data/minecraft/recipes/` directory.
+        *   Read all the "smelting" and "blasting" recipes from the `server.jar`.
+        *   Create new "blasting" recipes for any that don't already have one.
+        *   Save all the new recipes into the `data/minecraft/recipes/` directory.
+
+3.  **Update `pack.mcmeta`**
+    *   Open the `pack.mcmeta` file.
+    *   Find the `pack_format` number and update it to match the new version of Minecraft. You can find a list of `pack_format` versions on the [Minecraft Wiki](https://minecraft.wiki/Pack_format).
+    *   For example, for Minecraft 1.21, the `pack_format` is `32`.
+
+4.  **Create the Datapack `.zip` file**
+    *   You are now ready to distribute the datapack.
+    *   Create a `.zip` file that contains the `data` directory and the `pack.mcmeta` file.
+    *   This `.zip` file is what you will place in the `datapacks` folder of your Minecraft world.
+
+This process *should* work until there are major changes to how Minecraft manages recipes, datapacks, ect.

+## TODO
+- [ ] Ensure everything works as expected on other devices
+- [ ] Perhaps create a Dockerfile, if there is a "latest-release" style download link
+- [ ] Publish on modpack sites (if there are no equivalents)
+- [ ] Maybe some better inline documentation could be cool.
