+
+This is an 11-unit unibody split keyboard with an exploded spacebar cluster on bottom
+
+* Keyboard Maintainer: [projectcain](https://github.com/yourusername)
+* Hardware Supported: Relic PCB
+* Hardware Availability: mechvault.net
+
+To reset the keyboard into bootloader mode, short the two pads labeled "Reset" on the left side of the pcb
+
+Make example for this keyboard (after setting up your build environment):
+
+    make projectcain/relic:default
+
