1st of all, go to the site linked above.
Now follow these steps:
- Input you crafting recipe into the grid;
- Turn on the options provided if you need to;
- Rename the recipe name in the "Output Recipe" blank to avoid interfering with vanilla recipes / other custom recipes;
- Click "Download datapack".
This will download the datapack you need to use the recipe in minecraft or submit to the jam.
If you want to add a second or however much you want recipes to a single pack, follow these additional steps after making the first recipe by the steps above:
- Repeat the previous steps for another recipe EXCEPT click "Download JSON file" instead of "Download Datapack";
- Now unarchive the existing datapack it or just work in it if you have a .zip opening tool;
- Open the folder by the path data/crafting/recipe and you should find your 1st recipe as a JSON file;
- Put the new JSON file next to the old one;
- If you unarchived the file archive it back to .zip format.
