+# Dumbo
+
+![Dumbo](https://i.imgur.com/EEqCZsgl.jpg)
+
+Inspired by the corne, kyria and chimera ergo 42, the dumbo is a split keyboard ready for a comfortable future (read: bluetooth and ergo).
+
+The Dumbo is a small split ergonomic keyboard with 44 keys (outer columns can be broken off to make it 38 keys), heavy columnar stagger, small and comfortable thumb cluster, support for two rotary encoders per half, support for OLEDs, and optional support for a JST-PH two-pin connector to attach a battery and an on/ofF switch to power Bluetooth Pro Micro replacements like the nice!nano.
+
+* Keyboard Maintainer: [Adam Naldal](https://github.com/adamnaldal)
+* Hardware Supported: Pro Micro and pin-compatible replacements like the nice!nano
+* Hardware Availability: NA
+
+Make example for this keyboard (after setting up your build environment):
+
+    make dumbo:default
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
