+# EVO70 R2
+
+EVO70 R2 is a 70% keyboard (65% w/left side function cluster) designed and produced by customMK. 
+
+![EVO70 R2](https://i.imgur.com/B1QMuIxh.jpeg)
+
+* Keyboard Maintainer: [customMK](https://github.com/customMK)
+* Hardware Supported: EVO70 R2
+* Hardware Availability: [customMK](https://shop.custommk.com/collections/evo70/products/evo70)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make custommk/evo70_r2:default
+
+Flashing example for this keyboard:
+
+    make custommk/evo70_r2:default:flash
+
+To enter the bootloader, run the flashing command above, and then either plug in the USB connection while holding the top-left key, or alternatively, plug in the USB connection and then press the reset button on the PCB located under the space bar.
+
+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).
