-mechmini
-========
-
-A compact ortholinear/staggered keyboard.
-
-Keyboard Maintainer: QMK Community
-Hardware Supported: mechmini PCB
-Hardware Availability: https://mechkeys.ca/collections/keyboards/products/mechmini-2-0-pcb
-
-Make example for this keyboard (after setting up your build environment):
-
-    make mechmini:default
-
-See [build environment setup](https://docs.qmk.fm/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) for more information.
-
-## Mechmini Notes
-
-Note that this is a complete replacement for the firmware, so you won't be
-using Bootmapper Client to change any keyboard settings, since not all the
-USB report options are supported.
-
-## Installing
-
-First, install the requirements. These commands are for OSX, but all you
-need is the AVR toolchain and `bootloadHID` for flashing:
-
-```
-$ brew cask install crosspack-avr
-$ brew install --HEAD https://raw.githubusercontent.com/robertgzr/homebrew-tap/master/bootloadhid.rb
-```
-
-In order to use the `./program` script, which can reboot the board into
-the bootloader, you'll need Python 2 with PyUSB installed:
-
-```
-$ pip install pyusb
-```
-
-Then, with the keyboard plugged in, simply run this command from the
-`qmk_firmware` directory:
-
-```
-$ make mechmini:program
-```
-
-If you prefer, you can just build it and flash the firmware directly with
-`bootloadHID` if you boot the board while holding down `L_Ctrl` to keep it
-in the bootloader:
-
-```
-$ make mechmini
-$ bootloadHID -r mechmini_default.hex
-```
-
-## Troubleshooting
-
-From my experience, it's really hard to brick these boards. But these
-tricks have been useful when it got stuck in a weird scenario.
-
-1. Try plugging the board in while pressing `L_Ctrl`. This will force it
-   to boot only the bootloader without loading the firmware. Once this is
-   done, just reflash the board with the original firmware.
-2. Sometimes USB hubs can act weird, so try connecting the board directly
-   to your computer or plugging/unplugging the USB hub.
