+This folder contains binary artifacts generated in lrr-firmware, which are used by the firmware tool.
+
+The stub binary here is not up to date, and only included to allow local debugging.
+It is written over with the most recent version during the [pages deployment action](https://github.com/little-red-rover/lrr-docs/blob/c47ad42e98806932c1cb93e0b3619bc2d0b2bffd/.github/workflows/deploy.yml#L37).
