+# armand1m crkbd layout
+
+This is the personal layout for [@armand1m](https://github.com/armand1m)
+
+This layout is heavily inspired in my personal Moonlander layout, optimized for my own personal usage.
+
+As of the date of this writing, my environment runs OS X Big Sur with yabai and skhd to provide an window tiling management experience similar to what i3wm offers to Linux, which means that I often use the `alt` keys.
+
+I am a huge fan of ModTaps, so this layout will contain some of those to allow for a better experience in such a small keyboard like the crkbd.
+
+## Usage
+
+In case you have `qmk` installed:
+
+```sh
+qmk compile -kb crkbd -km armand1m
+```
+
+The compiled .hex file should be available in `qmk_firmware/.build`
+
+You can also trigger a build and flash automatically by running the following command:
+
+```sh
+qmk flash -kb crkbd -km armand1m
+```
+
+If you built your crkbd with an Elite-C microcontroller, you probably want to use a DFU bootloader:
+
+```sh
+qmk flash -kb crkbd -km armand1m -bl dfu
+```
