-# French hacker layout
-
-## Introduction
-
-[Colemak Mod-DH](https://colemakmods.github.io/mod-dh/) layout for
-users keeping an `azerty` layout configuration on their OS.
-
-This keymap is for users keeping their operating systems configured with
-`azerty` - for typing passwords or in their native languages - but who
-wants a Colemak Mod-DH layout on their mechanical.
-
-The symbols layers was done after analysing various programming
-languages sources codes and should be close to optimal for typing
-confort.
-
-Special macros for [Qubes OS](https://www.qubes-os.org/) are included.
-
-There is an accented characters layer for infrequent typing of french
-accents.
-
-Special macros for [Qubes OS](https://www.qubes-os.org/) are included.
-
-## Build
-
-    cd keyboards/ergodox
-    make french_hacker
-
-## Design explanations
-
-See my [blog post](http://dialectical-computing.de/blog/blog/2017/01/29/a-better-coder-layout-for-the-ergodox-ez-keyboard/).

-xd75 keyboard firmware
-======================
-
-The XD75Re is a 15x5 full-grid ortholinear keyboard manufactured by XIUDI. This port of the QMK firmware is my first shot at using QMK, so if you see any features done wrong (or just plain missing), feel free to fix them and put in a pull request!
-
-## Quantum MK Firmware
-
-For more info on this firmware (and how to make it your own), head over to [qmk.fm](http://qmk.fm).
-
-## Building
-
-Download or clone the whole firmware and navigate to the keyboards/xd75 folder. Once your dev env is setup, you'll be able to type `make` to generate your .hex - you can then use the Teensy Loader to program your .hex file. 
-
-Depending on which keymap you would like to use, you will have to compile slightly differently.
-
-### Default
-
-To build with the default keymap, simply run `make default`.
-
-### Other Keymaps
-
-The "default" keymap included is basically the OLKB Atomic keymap with a few buttons added for RGB underglow control. This should be usable as a starting point, but most people will be best served creating their own keymap and flashing it - more info on creating your own keymap is available in [the official QMK documentation](https://docs.qmk.fm).
-
-To build the firmware binary hex file with a keymap just do `make` with a keymap like this:
-
-```
-$ make [default|jack|<name>]
-```
-
-Keymaps follow the format **__\<name\>.c__** and are stored in the `keymaps` folder.
