+
+
+This base keyboard has  SX83099 IC causes some problems. I needed QMK as an alternative, especially since the controller freezes when the backlight is off.
+
+* Keyboard Maintainer: [Coom](https://github.com/coomstoolbox)
+* Hardware Supported: Ziyoulang K3,Blue Pill
+* Hardware Availability: [Base Keyboard](https://www.aliexpress.com/item/1005005458088199.html), [Blue Pill Board](https://www.aliexpress.com/item/32812837487.html)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make handwired/ziyoulang_k3_mod:default
+
+Flashing example for this keyboard:
+
+    make handwired/ziyoulang_k3_mod: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).

+
+## Bootloader
+
+Enter the bootloader in 2 ways:
+
+* **Bootmagic reset**: Hold down the key at (0,0) in the matrix (usually the top left key or Escape) and plug in the keyboard
+* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available
