+# [🐦 @rjhilgefort](https://twitter.com/rjhilgefort)'s Corne KBD (CRKBD) Layout
+
+My Corne KBD layout is inspired by [my Planck Layout](../../../planck/keymaps/rjhilgefort/readme.md), but with some additional features. Namely, this layout has Linux support.
+
+![](https://imgur.com/wp9ksTIh.jpg)
+![](https://imgur.com/fnyiCnEh.jpg)
+
+## Features
+
+Here's some highlights/features of the layout.
+
+-   Ergonomic symbols layer.
+-   Media and Numpad layer.
+-   Planck-like extra tri-layer when holding the other two layers.
+-   Supports Mac and Linux as 1st class citizens giving each a dedicated base layer and a media layer for each that matches media keys for each OS. The Linux default layer focuses on `Ctrl` instead of `Super` and vice versa for Mac. (When you set Linux as your base layer, the Linux media layer is what you shift into. Same for the Mac layer when that's the base)

+## Building And Flashing
+
+Note, you'll see that most `crkbd`'s recommend a target of `avrdude` because most kits come with a Pro Micro. I put a Elite-C on mine and thus the target is `dfu`. You can see this in the [rules.mk](./rules.mk) as the `BOOTLOADER` configuration.
+
+#### CLI
+
+```
+make crkbd:rjhilgefort:flash
+```
+
+#### Docker
+
+```
+util/docker_build.sh crkbd:rjhilgefort:flash
+```
