+
+A compact 70keys keyboard (prototype) designed by mtei
+
+* Keyboard Maintainer: [mtei](https://github.com/mtei)
+* Hardware Supported: Pro Micro (ATmega32U4) & 74HC157
+* Hardware Availability: This is just prototype
+
+Make example for this keyboard (after setting up your build environment):
+
+ make symmetric70_proto:default
+
+Flashing example for this keyboard:
+
+ make symmetric70_proto:default:flash
+
+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).
