+# Ladduro keymap for Keychron Q2 (ANSI rev_0110) v1.01
+
+This keymap ports Q1 logic (by gtg465x) for RGB caps lock indicator and layer RBG assigned key.
+
+## Features:
+- On macOS, F3 opens Mission Control and F4 opens Launchpad without needing to configure shortcuts in System Preferences
+- RGB lighting turns off when the computer sleeps
+- Caps Lock and alpha keys turn red to indicate when Caps Lock is on
+- When the Fn layer is active, RGB lighting turns off for keys that are not assigned
+
+Make example for this keyboard (after setting up your build environment):
+
+    make keychron/q2/rev_0110:ladduro
+
+Flashing example for this keyboard:
+
+    make keychron/q2/rev_0110:ladduro: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).
+
+## Changelog
+
+### 14/03/2021 - 1.
+
+- Initial release
+
+### 02/04/2021 - 1.01
+
+- Remove via enable from rules.mk as it breaks the layout for some reason
