+## Description
+
+This keymap adds support for [Vial](https://get.vial.today) to the JD45.
+
+## Caveats
+
+This firmware has only been tested on the [Phoenix 45](https://p3dstore.com/products/phoenix-pcb-only) PCB, which is a drop-in replacement for the original JD45 PCB. The Phoenix 45 uses the JD45 QMK config. Some of the configurations may not be supported on the JD45.
+
+## TODO
+* Add support for rotary encoders
+* Create a more robust starting keymap
