+# Cepstrum
+
+A split 65XT staggered keyboard made and sold by Keebio. [More info at Keebio](https://keeb.io).
+
+* Keyboard Maintainer: [Bakingpy/nooges](https://github.com/nooges)
+* Hardware Availability: [Keebio](https://keeb.io/)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make keebio/cepstrum/rev1:default
+
+Example of flashing this keyboard:
+
+    make keebio/cepstrum/rev1:default:flash
+
+Handedness detection is already hardwired onto the PCB, so no need to deal with `EE_HANDS` or flashing .eep files.
+
+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).
+
+## Bootloader
+
+Enter the bootloader in one of these ways:
+
+* **Physical reset button**: Press and hold the button on the back of the PCB for at least 2 seconds and let go, or double-press the button
+* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available
+
+A build guide for this keyboard can be found here: [Keebio Build Guides](https://docs.keeb.io)
