This repository aims to collect Minecraft tags in the convention namespace c, which may be used by multiple mods to express similar things.
Drop the mod jar files you want to extract tags from into a mods subfolder and run the collect_mod_tags.py script.
This will update the tags.json file (incrementally, existing tags will not be removed).
Then run to_mediawiki.py to generate the Mediawiki text for the wiki.
