+# waffling80
+
+A TKL PCB attempting a87 and a88 compatibility with different switch and layout-options. 
+
+* Keyboard Maintainer: [4pplet](https://github.com/4pplet)
+* Hardware Supported: [waffling80](https://github.com/4pplet/waffling80)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make 4pplet/waffling80/rev_b: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).
+
+How to enter bootloader (DFU):
+* Hold the reset-header for a few seconds on the back of the PCB for keyboard to enter DFU. When in DFU, it's ready to flash the firmware.
+
+Alternative option if the firmware is already pre-flashed:
+* Unplug your keyboard, hold down the Esc key, plug in your keyboard and wait a second before releasing the keys. The keyboard will enter DFU and is ready to flash the firmware.
