Simple script to create metadata for NFTs that are already generated.
Add images to /assets folder, enter base info in main.rb, then run with:
ruby main.rb
JSON is written to /output folder 😶🌫️
If you need to duplicate a file (for something like a minting pass) - add file to /assets folder and run ruby dupe.rb, then run the main.rb script to apply metadata to the files.
