Hey there 👋 This is a super simple Trello Power-Up that adds card numbers to the front of cards for easy reference.
To enable it, go to the Power-Up admin page: https://trello.com/power-ups/admin
Add a new powerup, and for the manifest URL use https://webrender.github.io/trello-card-numbers/manifest.json
After adding, the Power-Up should be available via your board menu.
