+LFK78/68
+===
+
+A 65% keyboard similar to the MagicForce68 or VA68M. Optional fuction key block on left side.
+
+Keyboard Maintainer: [LFKeyboards](https://github.com/lfkeyboards)  
+Hardware Supported: LFK78/68 RevB - RevJ, SMK78/68  
+Hardware Availability: [LFKeyboards.com](https://www.lfkeyboards.com/)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make lfkeyboards/lfk78:default
+
+See [build environment setup](https://docs.qmk.fm/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) for more information.
