## Pseudo US Layout
On a Japanese Windows environment, ANSI keyboards may be recognized wrongly as a JIS keyboard.
By using this code, you can use your ANSI keyboard under a JIS keyboard environment without changing the settings and registry of your environment.

A split wireless 40% column-staggered keyboard
Keyboard Maintainer: [SatT](https://github.com/satt99)
Hardware Supported: Comet46 PCB, atmega32u4, nRF51822
Hardware Availability: [Comet46 PCB, case, and receiver](https://github.com/satt99/comet46-hardware)
Firmware for nordic MCUs: [SRC and precompiled](https://github.com/satt99/comet46-firmware)
Make example for this keyboard (after setting up your build environment):
make satt/comet46:default
See [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) then the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information.
