+# Multibadge
+
+This is like the original Badge app that comes with the Badger, but with
+some additional things:
+
+* You can have multiple badges that you switch between with the up
+  and down arrow buttons.
+* Each badge can have a rotating display of messages (think URLs,
+  contact info, cute messages, etc).
+* The config file is in JSON to better support multiple badge data.
+
+I removed the company field, because I had no use for it. I'd rather have more
+space for the name shown on the badge. The image size is the same, so it's
+easy to upgrade from `badge` to `multibadge`.
+
+## Installation
+
+* Customize `multibadge.json`
+* Copy `multibadge.py` to `examples` on the Badger 2040
+* Copy `multibadge.json` to `badges`
+* Start `multibadge` from BadgerOS
