+# NuPhy Air75 V2
+
+*NuPhy Air75 V2 is a standard 84 key keyboard.*
+![NuPhy Air75 V2](https://i.imgur.com/R7jS2JC.jpeg)
+
+* Keyboard Maintainer: [nuphy](https://github.com/nuphy-src)
+* Hardware Supported: NuPhy Air75 V2 PCB
+* Hardware Availability: [link](https://nuphy.com/products/air75-v2)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make nuphy/air75_v2/ansi:default
+
+Flashing example for this keyboard:
+
+    make nuphy/air75_v2/ansi: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 one way:
+
+* **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
