+# Pterodactyl Default Configuration
+
+## Changelog
+
+* Nov 2017:
+  * Copied and adapted from the Ergodox EZ equivalent
+  * Notable differences:
+    - Don't try to have the columns that don't exist, naturally
+    - Removed RGB keys, since there are no RGB LEDs in the Dactyl (as designed, at least)
+* May 2020:
+  * Copied and adapted from dactyl base
+  * Notable differences:
+    - Support for Bluetooth via default Adafruit Feather 32u4
+    - Assumes processor lives in left half of split, not right
