+![Prime_EXL](https://i.imgur.com/3t524g8.jpg)
+
+An ergonomic 45% keyboard with a macro/numpad added to the left side. 
+
+Keyboard Maintainer: [Holtenc](https://github.com/holtenc/)  
+Hardware Supported: Prime_EXL PCB, ATMega32u4  
+Hardware Availability: Prototype
+
+Make example for this keyboard (after setting up your build environment):
+
+    make handwired/prime_exl: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).
