+# 大星外设 DXWS Star75
+
+75% Hotswap PCB with optional rotary encoder.
+
+![View of Star75 Keyboard](https://i.imgur.com/UrvnjiZ.jpeg)
+![Star75 Default Layout](https://i.imgur.com/LkTP0Cj.png)
+
+* Keyboard Maintainer: QMK Community
+* Hardware Supported: Star75 1.2mm Flex-cut Hotswap PCB
+* Hardware Availability: [大星外设](https://item.taobao.com/item.htm?id=656392112467)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make star75:default
+
+Flashing example for this keyboard:
+
+    make star75: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 `RESET` if it is available
