+A customizable 60% keyboard.
+
+* Keyboard Maintainer: [Keychron](https://github.com/keychron)
+* Hardware Supported: Keychron V4
+* Hardware Availability: [Keychron](https://www.keychron.com)
+
+Make example for this keyboard (after setting up your build environment):
+
+ make keychron/v4/ansi:default
+
+Flashing example for this keyboard ([after setting up the bootloadHID flashing environment](https://docs.qmk.fm/#/flashing_bootloadhid))
+
+ make keychron/v4/ansi:default:flash
+
+**Reset Key**: Hold down the key located at *K00*, commonly programmed as *Esc* while plugging in the keyboard.
+
+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).
