+## Firmware building
+Clone the QMK Repo and install dfu-programmer, flash with:
+
+ make ergotaco:default:dfu
+
+And reset your keyboard!
+
+To just test if your build system is sane, try compiling the default keymap using:
+
+ make ergotaco: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).
