+![a52gl](https://cdn-ak.f.st-hatena.com/images/fotolife/S/Salicylic_acid3/20210911/20210911005227.jpg)
+
+This is 52 keys Alice style keyboard.
+Use the GL516 case.
+
+* Keyboard Maintainer: [Salicylic_acid3](https://github.com/Salicylic-acid3)
+* Hardware Supported: a52gl PCB, Pro Micro
+* Hardware Availability: [PCB & Case Data](https://github.com/Salicylic-acid3/GL516_Exemple), [yushakobo Shop](https://shop.yushakobo.jp/products/3342)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make gl516/a52gl:default
+
+## Bootloader
+
+Enter the bootloader in 3 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
+* **Physical reset button**: Briefly press the button on the back of the PCB - some may have pads you must short instead
+* **Keycode in layout**: Press the key mapped to `RESET` if it is available
+
+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).

+
+This is 73 keys Japanese style keyboard.
+Use the GL516 case.
+
+* Keyboard Maintainer: [Salicylic_acid3](https://github.com/Salicylic-acid3)
+* Hardware Supported: j73gl PCB, Pro Micro
+* Hardware Availability: [PCB & Case Data](https://github.com/Salicylic-acid3/GL516_Exemple), [yushakobo Shop](https://shop.yushakobo.jp/products/3342)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make gl516/j73gl:default
+
+## Bootloader
+
+Enter the bootloader in 3 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
+* **Physical reset button**: Briefly press the button on the back of the PCB - some may have pads you must short instead
+* **Keycode in layout**: Press the key mapped to `RESET` if it is available
+
+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).

+
+This is 51 keys Custom keyboard.
+Use the GL516 case.
+
+* Keyboard Maintainer: [Salicylic_acid3](https://github.com/Salicylic-acid3)
+* Hardware Supported: nknl7 PCB, Pro Micro
+* Hardware Availability: [PCB & Case Data](https://github.com/Salicylic-acid3/GL516_Exemple)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make gl516/n51gl:default
+
+## Bootloader
+
+Enter the bootloader in 3 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
+* **Physical reset button**: Briefly press the button on the back of the PCB - some may have pads you must short instead
+* **Keycode in layout**: Press the key mapped to `RESET` if it is available
+
+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).
