+This is the Linux-penguin again...
+
+Originally drewn by Larry Ewing (http://www.isc.tamu.edu/~lewing/)
+(with the GIMP) the Linux Logo has been vectorized by me (Simon Budig,
+http://www.home.unix-ag.org/simon/).
+
+This happened quite some time ago with Corel Draw 4. But luckily
+meanwhile there are tools available to handle vector graphics with
+Linux. Bernhard Herzog (bernhard@users.sourceforge.net) deserves kudos
+for creating Sketch (http://sketch.sourceforge.net), a powerful free
+tool for creating vector graphics. He converted the Corel Draw file to
+the Sketch native format. Since I am unable to maintain the Corel Draw
+file any longer, the Sketch version now is the "official" one.
+
+Anja Gerwinski (anja@gerwinski.de) has created an alternate version of
+the penguin (penguin-variant.sk) with a thinner mouth line and slightly
+altered gradients. It also features a nifty drop shadow.
+
+The third bird (penguin-flat.sk) is a version reduced to three colors
+(black/white/yellow) for e.g. silk screen printing. I made this version
+for a mug, available at the friendly folks at
+http://www.kernelconcepts.de/ - they do good stuff, mail Petra
+(pinguin@kernelconcepts.de) if you need something special or don't
+understand the german  :-)
+
+These drawings are copyrighted by Larry Ewing and Simon Budig
+(penguin-variant.sk also by Anja Gerwinski), redistribution is free but
+has to include this README/Copyright notice.
+
+The use of these drawings is free. However I am happy about a sample of
+your mug/t-shirt/whatever with this penguin on it...
+
+Have fun

 # ErgoDox EZ Utilities
 
+## compile_keymap.py
+
 The Python script in this directory, by [mbarkhau](https://github.com/mbarkhau) allows you to write out a basic ErgoDox EZ keymap using Markdown notation, and then transpile it to C, which you can then compile. It's experimental, but if you're not comfortable using C, it's a nice option.
+
+## keymap_beautifier.py
+
+This Python 3 script, by [Tsan-Kuang Lee](https://github.com/tsankuanglee) takes the keymap.c downloaded from [ErgoDox EZ Configurator](https://configure.ergodox-ez.com/) and beautifies it for easier customization, allowing one to quickly draft a layout to build upon.
+
+See [README.md](./keymap_beautifier/README.md) for this utility for more details.

+
+![Moonlander](https://zsa.io/static/gallery-white-case-7a2ef555f8f7f4ce1b9030477b16e517.png)
+
+A next-gen split, ergonomic keyboard with an active left side, USB type C, integrated wrist rest, and a thumb cluster that can move.
+
+
+* Keyboard Maintainer: [drashna](https://github.com/drashna), [ZSA](https://github.com/zsa/)
+* Hardware Supported: Moonlander MK 1 (STM32F303xC)
+* Hardware Availability: [ZSA Store](https://zsa.io/moonlander/)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make moonlander:default
+
+Flashing example for this keyboard:
+
+    make moonlander:default:flash
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
+
+## Oryx Configuation
+
+If you're using the Smart LED (layer indication) feature from the Oryx Configurator, you want to make sure that you enable these options by adding `#define ORYX_CONFIGURATOR` to your keymap's `config.h`. 
+
+This changes the `RGB_TOG` keycode so that it will toggle the lights on and off, in a way that will allow the Smart LEDs to continue to work, even with the rest of the LEDs turned off. 
+
+Additionally, a new keycode has been added to toggle the Smart LEDs.  Use `TOGGLE_LAYER_COLOR`, if you aren't already.

+ *
+ * audio.[ch] takes care of all overall state, tracking the actively playing
+ *            notes/tones; the notes a SONG consists of;
+ *            ...
+ *            = everything audio-related that is platform agnostic
+ *
+ * driver_[avr|chibios]_[dac|pwm] take care of the lower hardware dependent parts,
+ *            specific to each platform and the used subsystem/driver to drive
+ *            the output pins/channels with the calculated frequencies for each
+ *            active tone
+ *            as part of this, the driver has to trigger regular state updates by
+ *            calling 'audio_update_state' through some sort of timer - be it a
+ *            dedicated one or piggybacking on for example the timer used to
+ *            generate a pwm signal/clock.
+ *
+ *
+ * A Note on terminology:
+ * tone, pitch and frequency are used somewhat interchangeably, in a strict Wikipedia-sense:
+ *    "(Musical) tone, a sound characterized by its duration, pitch (=frequency),
+ *    intensity (=volume), and timbre"
+ * - intensity/volume is currently not handled at all, although the 'dac_additive' driver could do so
+ * - timbre is handled globally (TODO: only used with the pwm drivers at the moment)
+ *
+ * in musical_note.h a 'note' is the combination of a pitch and a duration
+ * these are used to create SONG arrays; during playback their frequencies
+ * are handled as single successive tones, while the durations are
+ * kept track of in 'audio_update_state'
+ *
+ * 'voice' as it is used here, equates to a sort of instrument with its own
+ * characteristics sound and effects
+ * the audio system as-is deals only with (possibly multiple) tones of one
+ * instrument/voice at a time (think: chords). since the number of tones that
+ * can be reproduced depends on the hardware/driver in use: pwm can only
+ * reproduce one tone per output/speaker; DACs can reproduce/mix multiple
+ * when doing additive synthesis.
+ *
+ * 'duration' can either be in the beats-per-minute related unit found in
+ * musical_notes.h, OR in ms; keyboards create SONGs with the former, while
+ * the internal state of the audio system does its calculations with the later - ms

+/* French AZERTY - AFNOR NF Z71-300
+ *
+ * A standard for the French keyboard
+ *
+ * The project was launched at the end of 2015 on the proposal of the General
+ * Delegation for the French language and the languages of France (Ministry
+ * of Culture), starting from the observation that the current "azerty"
+ * keyboards constrain the writing of French, languages regional and European
+ * languages with Latin alphabet.
+ *
+ * For the first time, a standard (NF Z71-300) defines the placement of
+ * characters on the French keyboard. It offers two layouts, one of which
+ * closely follows the QWERTY keyboard used by most people who write in French.
+ *
+ * However, it is in many ways superior to the old keyboard:
+ *
+ * - it contains all the characters required to enter text in French (for example É, œ and ")
+ * - it is designed to be more ergonomic and allow faster typing
+ * - it includes almost 60 additional characters for entering foreign languages, technical content, etc
+ * - however, the characters remain easy to locate thanks to intuitive groupings
+ *

 This purpose of this fork is maintain a clean repo that only contains the keyboard code that we need, and as little else as possible.  This is to keep it lightweight, since we only need a couple of keyboards. This is the repo that the EZ Configurator will pull from. 
+## Documentation
+
+* [See the official documentation on docs.qmk.fm](https://docs.qmk.fm)
+
+The docs are powered by [Docsify](https://docsify.js.org/) and hosted on [GitHub](/docs/). They are also viewable offline; see [Previewing the Documentation](https://docs.qmk.fm/#/contributing?id=previewing-the-documentation) for more details.

+You can request changes by making a fork and opening a [pull request](https://github.com/qmk/qmk_firmware/pulls), or by clicking the "Edit this page" link at the bottom of any page.

 ## Strategy
 
 To keep PRs small and easier to test, they should ideally be 1:1 with commits from QMK Firmware master. They should only group commits if/when it makes sense. Such as multiple commits for a specific feature (split RGB support, for instance)
-
-## Merging
-
-Pull Requests should be merged/rebased, not squashed, so we can maintain a commit history that is close to QMK Firmware's, for ease of reference.
