+# Halcyon Corne's Default Keymap
+_This keymap is a copy of the [Corne default keymap](https://github.com/qmk/qmk_firmware/tree/master/keyboards/crkbd/keymaps/default)_
+
+A simple default keymap for the Halcyon Corne
+============================================
+
+Keymaps in general are quite personal, so it is difficult to come up with a default that will suit every user. We hope this keymap serves as a good starting point for your own - although it should be fairly usable out-of-the-box.
+
+What do all these layers do?
+----------------------------
+
+### Layer 0: Base layer
+
+![Layer 0](https://i.imgur.com/Ri5cTHqh.png)
+
+This is where your basic letters live.
+
+The homing thumb fingers are used to access the different layers.
+
+* The homing left thumb finger gives access to the Numbers (or lower) layer
+* The homing right thumb finger gives access to the Symbols (or raise) layer
+* Pressing both homing thumb fingers gives access to the Adjust layer
+
+### Layer 1: Lower
+
+![Layer 1](https://i.imgur.com/9h6ZRQLh.png)
+
+The Lower layer gives access to your number keys on the top row. It also exposes the arrow keys in the usual Vim-style layout.
+
+### Layer 2: Raise
+
+![Layer 2](https://i.imgur.com/U1pf7pJh.png)
+
+The Raise layer gives access to the symbols. In addition to shifted number keys on the top row, the right hand also exposes the remaining symbol keys, both as shifted and non-shifted variants.
+
+### Layer 3: Adjust
+
+![Layer 3](https://i.imgur.com/A6z1DCbh.png)
+
+The Adjust layer exposes RGB adjustment keys on the left hand.
+
+Where is the keymap.c?
+----------------------
+
+The keymap.c file is not published to the repository. It is generated from `keymap.json` by the build system.
+
+This avoids duplicating information and allow users to edit their keymap from the QMK Configurator web interface.
+
+How do I edit and update the keymap?
+------------------------------------
+
+The `keymap.json` file is generated from the QMK Configurator interface and formatted for better readability in the context of the Ferris keyboard.
+
+To edit it, you may:
+* Edit it directly from a text editor.
+* Edit it from the QMK Configurator.
+
+If you decide to use the latter workflow, here are the steps to follow:
+
+* From the [QMK Configurator](https://config.qmk.fm/#/splitkb/halcyon/corne/rev2/LAYOUT_split_3x5_3), hit the "import QMK keymap json file" button (it has a drawing with an up arrow on it).
+* Browse to the location of your keymap (for example, `<your qmk repo>/keyboards/splitkb/halcyon/corne/keymaps/default/keymap.json`)
+* Perform any modification to the keymap in the web UI
+* Export the keymap to your downloads folder, by hitting the "Export QMK keymap json file" button (it has a drawing with a down arrow on it)
+* Replace your original keymap with the one you just downloaded
+
+I want to do more than the JSON format supports!
+-------------------------------------------------
+
+While the `json` format is easy to use, it does lack certain functionality - most notably custom OLED or encoder behaviour.
+
+To add this, you need to convert it to the `c` format. Do keep in mind that this is generally a one-way operation.
+
+First, from the root of your qmk repo, move to your keymap folder
+
+```bash
+cd ./keyboards/splitkb/halcyon/corne/keymaps/my_personal_keymap
+```
+
+Next, convert your `keymap.json` to a `keymap.c`
+
+```bash
+qmk json2c -o keymap.c keymap.json
+```
+
+
+You can add custom C code to the newly generated `keymap.c` file. Do note that you have to use **either** a C file **or** a JSON file - you cannot do both!
+**If a JSON file is present, the C file is ignored.**

+# Halcyon Corne
+
+![splitkb/halcyon/corne](https://i.imgur.com/Cpo2dM8.png)
+
+The Halcyon Corne rev2 is the second Corne revision and the third keyboard in our Halcyon range. Similar to Aurora, all keyboards in the series share the same feature set. The key highlights:
+
+- Halcyon keyboards come preassembled! You won't need a soldering iron.
+- You'll be able to install [VIK](https://github.com/sadekbaroudi/vik) modules.
+- It'll come fully documented, which includes the unboxing, assembly (with only a screwdriver), first installation and some advanced use cases.
+- Both the connection to the host device as well as the interconnect between the keyboard halves use USB C.
+- The controller has full ESD protection on all USB C ports, as well as all switch matrix GPIO!
+- The controller is interchangable. If part of your keyboard ever breaks, we can replace just the bits that need replacing.
+
+* Keyboard Maintainer: [splitkb.com](https://github.com/splitkb.com)
+* Hardware Availability: [splitkb.com](https://splitkb.com).
+
+Make example for this keyboard (after setting up your build environment):
+
+ make splitkb/halcyon/corne/rev2:default
+
+The keyboard can be flashed by copying the resulting `.uf2` file onto the `RPI-RP2` flash drive.
+
+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).
+
+## Bootloader
+
+Enter the bootloader in 3 ways:
+
+* **Reset button**: Double-tap the reset button at the top of the controller, right above the USB-C port.
+* **Bootloader reset**: Hold down the "Boot" button and plug in the keyboard.
+* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available.

+# Halcyon Elora's Default Keymap
+
+The default keymap contains 5 layers which allows it to include all keys found on an ANSI layout TKL keyboard plus media keys.
+Hardware features of the Elora such as rotary encoders and underglow are also supported.
+
+The Elora keymap is in essence identical to the Kyria keymap, just with an additional number row. A deep dive into the keymap is provided there.
+
+The five different layers are the following:
+1. Base layer (QWERTY, Colemak-DH or Dvorak)
+2. Navigation layer
+3. Symbols/Numbers layer
+4. Function layer
+5. Adjust layer
+
+## Base layer(s)
+```
+Base Layer: -

+ `----------------------------------' `----------------------------------'
+```
+Three different well-known keyboard layouts are provided to fill in the placeholder `-` keys: QWERTY, Colemak-DH, and Dvorak. The default layer can be changed at runtime, more info on that in the section on the [adjust layer](#adjust-layer).
+
+For the rest of this write-up, the base layer will be assumed to be QWERTY and will be used as a reference to describe physical keys, e.g. “<kbd>B</kbd> key” vs, the much more verbose, “lower inner index key”.

+ | | | Enter| | | | | | | | |
+ `----------------------------------' `----------------------------------'
+```
+
+Aside from variations in the alpha cluster, the rest of the base keys remain the same and are designed to feel familiar.

+After making transformations to the classic ANSI US QWERTY TKL 60% to arrive to the layout of the Elora, as illustrated in the animation above, the result looks like this:
+
+```
+,-------------------------------------------. ,-------------------------------------------.

+`----------------------+------+------+------+------+------| |------+------+------+------+------+----------------------'
+ | LCtrl| LGUI | LAlt | Space| | | | Space| AltGr| RGUI | Menu |
+ | | | | | | | | | | | |
+ `----------------------------------' '----------------------------------'
+```
+
+First thing to notice is the presence of blank keys. To fill in the blank keys above the <kbd>Space</kbd> keys, we can take inspiration from other split keyboards featuring an extra inner index column on each half. A common mapping for those kind of keys are the bracket keys that got removed in the fourth step of the animated transformation. The thumb keys besides <kbd>Space</kbd>s is prime real estate for dedicated layer-switching keys. It doesn't matter on which side is assigned the sym-layer-switch key but it helps to keep the nav-layer-switch on the left in order to keep the arrow keys on the right side like on a classic keyboard, so we'll put nav on the left and sym on the right. We'll address the remaining blank thumb keys later.
+
+The base layer is starting to form but there remains some flaws. One glaring issue is the position of Control. Control is a very commonly used function but the key on which it sits right now is way too tucked in under the hand to be able to press it comfortably with either the thumb or the pinky from resting position. In fact, installing a rotary encoder there is a common move among Elora users and I guarantee you that activating Control by holding down a rotary encoder does not spark joy. Instead, let's employ a popular trick that involves remapping the current Caps Lock key, which is positioned at a comfortable position on the keyboard, to Control.
+
+We can go further though; a variant of this trick makes the Control key produce Escape when tapped. This is called a “modtap”. There is no use to tapping Control by itself without chording it with another key and there is no use to holding down the Esc key so why not combine the two into a single key?
+
+All of this leaves us with three blank keys.
+
+```
+,-------------------------------------------. ,-------------------------------------------.
+| Esc | 1 | 2 | 3 | 4 | 5 | | 6 | 7 | 8 | 9 | 0 | Esc |
+|--------+------+------+------+------+------| |------+------+------+------+------+--------|
+| Tab | Q | W | E | R | T | | Y | U | I | O | P | Bksp |
+|--------+------+------+------+------+------| |------+------+------+------+------+--------|
+|Ctrl/Esc| A | S | D | F | G | | H | J | K | L | ; : | ' " |
+|--------+------+------+------+------+------+-------------. ,-------------+------+------+------+------+------+--------|
+| LShift | Z | X | C | V | B | [ { | | | | ] } | N | M | , < | . > | / ? | RShift |
+`--------+-------------+--------------------+------+------| |------+------+--------------------+------+---------------'
+ | | LGUI | LAlt | Space| Nav | | Sym | Space| AltGr| RGUI | Menu |
+ | | | | | | | | | | | |
+ `----------------------------------' '----------------------------------'
+```
+
+These keys are not easily reachable while touch typing (that is, not reachable without picking up your hand) and should thus be associated with functions that you are not likely to be typed within a stream of text. The idea is that if you have to pick up your hand to hit a key, you want it to be at a time when you are likely to be pausing your interaction with the machine, rather than in the midst of a flurry of typing. They're thus well suited for accessing the adjust layer and the function layer. We can also toss in Caps Lock even though it is an editing-type function that gets used within a stream of text because shouting in ALL-CAPS should be a deliberate action.
+
+```
+,-------------------------------------------. ,-------------------------------------------.
+| Esc | 1 | 2 | 3 | 4 | 5 | | 6 | 7 | 8 | 9 | 0 | Esc |
+|--------+------+------+------+------+------| |------+------+------+------+------+--------|
+| Tab | Q | W | E | R | T | | Y | U | I | O | P | Bksp |
+|--------+------+------+------+------+------| |------+------+------+------+------+--------|
+|Ctrl/Esc| A | S | D | F | G | | H | J | K | L | ; : | ' " |
+|--------+------+------+------+------+------+-------------. ,-------------+------+------+------+------+------+--------|
+| LShift | Z | X | C | V | B | [ { |CapsLk| |F-keys| ] } | N | M | , < | . > | / ? | RShift |
+`----------------------+------+------+------+------+------| |------+------+------+------+------+----------------------'
+ |Adjust| LGUI | LAlt | Space| Nav | | Sym | Space| AltGr| RGUI | Menu |
+ | | | | | | | | | | | |
+ `----------------------------------' `----------------------------------'
+```
+
+The next glaring issue is the absence of an Enter key on the current base layer this far. Enter is a very frequently used key so it deserves to be placed at a good spot in the keymap. The best way to insert it in the keymap with minimal changes to the current layout is to use modtaps. A tempting solution is to turn the <kbd>RShift</kbd> key into a <kbd>RShift/Enter</kbd> modtap but that can result in chat messages sent too frustratingly early when you're not used to it. Using GUI is also sub-optimal because tapping the GUI modifier actually has a use as opposed to taps of the Control or the Shift key. Pressing and releasing the GUI key by itself opens the App menu in many desktop environments. The natural choice is thus <kbd>LAlt/Enter</kbd>. That way, Enter is 1u away from resting thumb position and is unlikely to get accidentally activated because Alt is very rarely used in the midst of prose.
+
+Finally, we're one Quality-Of-Life update away from the actual base layer. <kbd>Ctrl/' "</kbd> not only preserves symmetry in the keymap with <kbd>Ctrl/Esc</kbd> but also helps balance the load between your pinkies and invites you to use both hands instead of contortions. Perhaps more importantly, it also frees you from the necessity of picking up your hand, breaking touch typing position and pressing a pinky key with your ring finger in order to execute Ctrl+A or Ctrl+Z. That becomes even more important on a board with such an aggressive pinky columnar stagger like the Elora.

+ `----------------------------------' `----------------------------------'
+```
+
+This is where you'll find all the keys that are generally between the main block of a classic keyboard and the numpad in addition to media controls and modifiers on easy access on the home row for fast and comfortable chording with navigation keys.
+
+Useful mnemonics:
+- “GACS” to remember the order of the modifiers on the left-hand home row
+- <kbd>Scroll Lock</kbd> is on the same key as <kbd>Caps Lock</kbd> because they're both locks
+- <kbd>Delete</kbd> is on the same key as <kbd>Backspace</kbd> because they both erase characters
+- <kbd>Home</kbd> is the leftmost position on the current line so it is above <kbd>←</kbd>. Same logic applies for <kbd>End</kbd>.
+- <kbd>Media Previous</kbd> = ⏮, <kbd>Media Next</kbd> = ⏭
+- <kbd>Page Up</kbd>, <kbd>Page Down</kbd> and <kbd>Volume Up</kbd>, <kbd>Volume Down</kbd> are positioned like the main <kbd>Up</kbd> and <kbd>Down</kbd> keys.
+
+## Sym layer
+```
+Sym Layer: Numbers, symbols
+
+,-------------------------------------------. ,-------------------------------------------.
+| | | | | | | | | | | | | |
+|--------+------+------+------+------+------| |------+------+------+------+------+--------|
+| ` | 1 | 2 | 3 | 4 | 5 | | 6 | 7 | 8 | 9 | 0 | = |
+|--------+------+------+------+------+------| |------+------+------+------+------+--------|

+`----------------------+------+------+------+------+------| |------+------+------+------+------+----------------------'
+ | | | | | | | | | | | |
+ | | | | | | | | | | | |
+ `----------------------------------' `----------------------------------'
+```
+The top row is the unshifted num row, the home row of the layer is the shifted num row and the bottom row contains the hyphen `-` and the underscore `_` on the best lower row spot because of how frequent they are as well as redundant symbols that are already present on the base layer but are reproduced here to avoid juggling back and forth between base, shift, and sym when typing a string of symbols.
+
+The layout of the first two rows needs no introduction, you're already used to them but it's worth looking into the structure of the bottom row.
+
+The two halves are mirrored in a sense. On the right, you can find <kbd>,</kbd> <kbd>.</kbd> <kbd>/</kbd> at their usual spots with the addition of <kbd>Shift</kbd>+<kbd>/</kbd>=<kbd>?</kbd> to the right of the <kbd>/</kbd> key to remove the need to press simultaneously <kbd>Sym</kbd> and a <kbd>Shift</kbd> key to access `?`.
+
+Now, if you look at the left side, you'll notice that the mirror of <kbd>,</kbd> is <kbd>;</kbd>, the mirror of <kbd>.</kbd> is <kbd>:</kbd> and the mirror of <kbd>/</kbd> is <kbd>\\</kbd>. The same logic used for <kbd>Shift</kbd>+<kbd>/</kbd>=<kbd>?</kbd> also applies to <kbd>Shift</kbd>+<kbd>\\</kbd>=<kbd>|</kbd>.
+
+In case you wish to combine <kbd>Shift</kbd> with a symbol key anyways, you can hold down <kbd>Shift</kbd> on the base layer with your pinky, activate <kbd>Sym</kbd> with your right thumb and while still holding down the <kbd>Shift</kbd> key, tap your desired symbol key. Same thing if you need <kbd>Ctrl</kbd>+<kbd>Digit</kbd>.
+
+## Function layer
+```
+Function Layer: Function keys
+
+,-------------------------------------------. ,-------------------------------------------.
+| | | | | | | | | | | | | |
+|--------+------+------+------+------+------| |------+------+------+------+------+--------|
+| | F9 | F10 | F11 | F12 | | | | | | | | |

+ | | | | | | | | | | | |
+ | | | | | | | | | | | |
+ `----------------------------------' `----------------------------------'
+```
+In a similar fashion to the nav layer, pressing down `FKEYS` with the right thumb enables a numpad of function keys on the opposite hand and modifiers on the right-hand home row. Once again, mirror symmetry is leveraged in this keymap for the order of the right-hand modifiers.
+
+The <kbd>Alt</kbd> modifier, despite being situated on the right half of the keyboard is *not* `KC_RALT`, it is `KC_LALT`. `KC_RALT` is actually the <kbd>AltGr</kbd> key which generally acts very differently to the left <kbd>Alt</kbd> key. Keyboard shortcuts involving <kbd>AltGr</kbd>+<kbd>F#</kbd> are rare and infrequent as opposed to the much more common <kbd>Alt</kbd>+<kbd>F#</kbd> shortcuts. Consequently, `KC_LALT` was chosen for the function layer.
+
+Since there are more than 10 function keys, the cluster of F-keys does not follow the usual 3×3+1 numpad arrangement.
+
+
+## Adjust layer
+```
+Adjust Layer: Default layer settings, RGB
+
+,-------------------------------------------. ,-------------------------------------------.
+| | | | | | | | | | | | | |
+|--------+------+------+------+------+------| |------+------+------+------+------+--------|
+| | | |QWERTY| | | | | | | | | |

+ | | | | | | | | | | | |
+ | | | | | | | | | | | |
+ `----------------------------------' `----------------------------------'
+```
+
+Default layer settings on the left and various RGB underglow controls on the right.
+
+The default layer settings are lined up on the middle finger column because the home middle finger key is <kbd>D</kbd> on QWERTY (like the “D” in “Dvorak”) and the lower middle finger key is <kbd>C</kbd> on QWERTY (like the “C” in “Colemak”). I can hear you say that “QWERTY” doesn't start with “E” but Dvorak and Colemak were already aligned in a column so the QWERTY may as well join the formation.
+
+NOTE: The default layer settings set by those keys are *NOT* stored in EEPROM and thus do not persist through boots. If you wish to change the default layer in a non-volatile manner, either change the order of the layers in the firmware, for example like so if you want to set Dvorak as the new default:
+```c
+enum layers {
+ _DVORAK = 0,
+ _QWERTY,
+ _COLEMAK_DH,
+ _NAV,
+ _SYM,
+ _FUNCTION,
+ _ADJUST
+};
+```
+or re-define the `QWERTY`, `COLEMAK` and `DVORAK` keys to point to custom keycodes starting on `SAFE_RANGE` and calling the `set_single_persistent_default_layer` function inside of `process_record_user`.
+
+## Hardware Features
+
+### Rotary Encoder
+The left rotary encoder is programmed to control the volume whereas the right encoder sends <kbd>PgUp</kbd> or <kbd>PgDn</kbd> on every turn.
+
+## Going further…
+
+This default keymap can be used as is, unchanged, as a daily driver for your Elora but you're invited to treat your keymap like a bonsai. At the beginning, it's just like the default keymap but from time to time, you can tweak it a little. Cut a little key here, let another combo grow there. Slowly but surely it will be a unique keymap that will fit you like a glove.

+# Halcyon Elora
+
+![splitkb/halcyon/elora](https://i.imgur.com/TbFWzsh.png)
+
+The Halcyon Elora rev2 is the second Elora revision and the second keyboard in our Halcyon range. Similar to Aurora, all keyboards in the series share the same feature set. The key highlights:
+
+- Halcyon keyboards come preassembled! You won't need a soldering iron.
+- You'll be able to install [VIK](https://github.com/sadekbaroudi/vik) modules.
+- It'll come fully documented, which includes the unboxing, assembly (with only a screwdriver), first installation and some advanced use cases.
+- Both the connection to the host device as well as the interconnect between the keyboard halves use USB C.
+- The controller has full ESD protection on all USB C ports, as well as all switch matrix GPIO!
+- The controller is interchangable. If part of your keyboard ever breaks, we can replace just the bits that need replacing.
+
+* Keyboard Maintainer: [splitkb.com](https://github.com/splitkb.com)
+* Hardware Availability: [splitkb.com](https://splitkb.com).
+
+Make example for this keyboard (after setting up your build environment):
+
+ make splitkb/halcyon/elora/rev2:default
+
+The keyboard can be flashed by copying the resulting `.uf2` file onto the `RPI-RP2` flash drive.
+
+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).
+
+## Bootloader
+
+Enter the bootloader in 3 ways:
+
+* **Reset button**: Double-tap the reset button at the top of the controller, right above the USB-C port.
+* **Bootloader reset**: Hold down the "Boot" button and plug in the keyboard.
+* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available. \ No newline at end of file

+# Halcyon Ferris's Default Keymap
+_This keymap is a copy of the [Ferris default keymap](https://github.com/qmk/qmk_firmware/tree/master/keyboards/ferris/keymaps/default), with the addition of RGB modifier keys._
+
+A usable default keymap for the Ferris keyboard
+===============================================
+
+Keymaps in general are quite personal, so it is difficult to come up with a default that will suit every user.
+
+This keymap makes heavy use of keys behaving differently when tapped and held, so that all the keys one may need remain accessible despite the low number of thumb keys.
+
+It comes with a number of layers to give access to most of the keys one may need on a keyboard. It is not meant to be the best possible keymap, but rather a good base on which to build a keymap that works for you.
+
+This is not the only way to make 34 keys a comfortable typing experience, but it is one way to do so. If you don't already know of a better way, this may be as good a starting point as any :)
+
+Note that this keymap was built from the perspective that it is OK to take a steep learning curve if it results in a keymap that is easier to use in the long run. This means that it may take more effort to learn this keymap than some alternatives. "Easy to use" was assessed against the workflow of the author, so your mileage may vary on some of the details.
+
+What do all these layers do?
+----------------------------
+
+### Layer 0: Base layer
+
+![Layer 0](https://raw.githubusercontent.com/splitkb/qmk_firmware/assets/aurora/sweep/keymaps/default/layer0.png)
+
+On tapping the keys, our base layer is qwerty with space on the right homing thumb and backspace on the left homing thumb.
+
+In this layer, the non-homing-thumb positions have 0 and 1. I recommend modifying this to some frequently accessed shortcut such as copy/paste, previous/next tab or anything that makes most sense in your own workflow. O and 1 are place-holders and make it easy to troubleshoot that all keys are working properly before soldering in the switches.
+The reason I recommend convenience shortcuts instead of more commonly used keys like tab or meta is that unhoming of the thumbs was a frequent source of typos for me when I used more than one thumb key frequently in the context of typing.
+
+Despite being missing on this layer, "meta", "tab", "esc" and such are accessible from any other layer: see Layer 7.
+
+The behaviour of some keys differ when held:
+* Both homing pinkies behave as shift.
+* Both bottom-row ring fingers behave as ctrl.
+* Both bottom-row middle fingers behave as alt.
+
+* The homing left ring finger gives access to the Function keys layer
+* The homing right ring finger gives access to the Numbers layer
+* The homing left middle finger gives access to the Mouse layer
+* The homing right middle finger gives access to the Navigation layer
+* The homing left index finger gives access to the Right symbols layer
+* The homing right index finger gives access to the Left symbols layer
+* The homing right thumb gives access to the Always accessible layer
+
+### Layer 1: Mouse
+
+![Layer 1](https://raw.githubusercontent.com/splitkb/qmk_firmware/assets/aurora/sweep/keymaps/default/layer1.png)
+
+Layer 1 is a mouse layer: it can be used one-handed or two-handed. The most common way to use it is two handed, with left and right click on the homerow of the left hand and directions on the homerow of the right hand.
+Scrolling is available on the right hand with mid finger up and down for vertical scroll and index and ring finger down for horizontal scroll.
+On the right hand, left click and right click are also available with index and ring finger up to allow one handed operation. This can be particularly handy when enabling the mouse layer permanently (no need to hold the left middle finger), which can be done from Layer 7.
+
+**Addition**: The Halcyon Ferris allows the RGB settings to be modified on this layer. This is an extra feature over the default Ferris keymap.
+
+### Layer 2: Navigation
+
+![Layer 2](https://raw.githubusercontent.com/splitkb/qmk_firmware/assets/aurora/sweep/keymaps/default/layer2.png)
+
+The navigation layer somewhat mirrors the mouse layer. It is accessed by holding the right middle finger and gives access to arrow keys on the left homerow. Page up and down, Home and End mirror the vertical scrolling and horizontal scrolling on the mouse layer.
+
+On the right hand, in addition to ctrl and alt which are available through transparency, ctrl + alt, ctrl + alt + shift and meta are accessible on the homerow to enable common shortcuts in some window managers. This part is quite workflow dependent, so make sure to adapt it to your own workflow as appropriate.
+
+### Layer 3: Right symbols
+
+![Layer 3](https://raw.githubusercontent.com/splitkb/qmk_firmware/assets/aurora/sweep/keymaps/default/layer3.png)
+
+When holding down the left index, one may access about half of the symbols. The pinkies store `^` and `$` symbols that represent begin and end in vim. The left homerow hosts `*` and `&`, symbols which are related in the way that they represent some form of indirection in programming languages such as rust. On the right hand, most symbols used when navigating the command line are stored together, organized by columns of related symbols.
+
+### Layer 4: Left symbols
+
+![Layer 4](https://raw.githubusercontent.com/splitkb/qmk_firmware/assets/aurora/sweep/keymaps/default/layer4.png)
+
+When holding down the right index, one may access the other symbols. On the left hand, most of the different brackets are laid out. The most frequent ones (round brackets and curly brackets) get a spot on the homerow. The rest of the layer hosts the remaining symbols that are easier to access here than on any other layers.
+
+### Layer 5: Function keys
+
+![Layer 5](https://raw.githubusercontent.com/splitkb/qmk_firmware/assets/aurora/sweep/keymaps/default/layer5.png)
+
+By holding down the left ring finger, one may access the function keys, roughly in a numpad layout.
+This means that alt+F4 is easy to type, with F4 being on the homerow.
+There is a shortcut for ctrl+alt on the left hand to enable convenient switching between virtual terminals on Linux.
+
+### Layer 6: Numbers
+
+![Layer 6](https://raw.githubusercontent.com/splitkb/qmk_firmware/assets/aurora/sweep/keymaps/default/layer6.png)
+
+The number layer is accessed by holding the right ring finger. It hosts the numbers and some duplicated symbols that are commonly accessed next to numbers, such as mathematical operators.
+The number are layed out similarly to a numpad, but with the middle row and the homerow swapped so that the most used numbers: 0, 1, 2 and 3 are all available in homing positions.
+
+### Layer 7: Always accessible
+
+![Layer 7](https://raw.githubusercontent.com/splitkb/qmk_firmware/assets/aurora/sweep/keymaps/default/layer7.png)
+
+Layer 7 is accessed by holding the right homing thumb down. Because this position is left transparent from every other layer, this layer is always accessible.
+It gives access to some essential keys that would typically be accessed on a thumb cluster or pinkies, such as meta, enter, tab, esc and delete.
+
+As the layer hosting esc, we duplicated some symbols here to allow for fast navigation in vim. For instance, esc, :, w, q can be done in a single roll.
+
+Where is the keymap.c?
+----------------------
+
+The keymap.c file is not published to the repository. It is generated from `keymap.json` by the build system.
+
+This avoids duplicating information and allow users to edit their keymap from the QMK Configurator web interface.
+
+How do I edit and update the keymap?
+------------------------------------
+
+The `keymap.json` file is generated from the QMK Configurator interface and formatted for better readability in the context of the Ferris keyboard.
+
+To edit it, you may:
+* Edit it directly from a text editor.
+* Edit it from the QMK Configurator.
+
+If you decide to use the latter workflow, here are the steps to follow:
+
+* From the [QMK Configurator](https://config.qmk.fm/#/splitkb/halcyon/ferris/rev1/LAYOUT_split_3x5_2), hit the "import QMK keymap json file" button (it has a drawing with an up arrow on it).
+* Browse to the location of your keymap (for example, `<your qmk repo>/keyboards/splitkb/halcyon/ferris/keymaps/default/keymap.json`)
+* Perform any modification to the keymap in the web UI
+* Export the keymap to your downloads folder, by hitting the "Export QMK keymap json file" button (it has a drawing with a down arrow on it)
+* Replace your original keymap with the one you just downloaded
+
+I want to do more than the JSON format supports!
+-------------------------------------------------
+
+While the `json` format is easy to use, it does lack certain functionality.
+
+To add this, you need to convert it to the `c` format. Do keep in mind that this is generally a one-way operation.
+
+First, from the root of your qmk repo, move to your keymap folder
+
+```bash
+cd ./keyboards/splitkb/halcyon/ferris/keymaps/my_personal_keymap
+```
+
+Next, convert your `keymap.json` to a `keymap.c`
+
+```bash
+qmk json2c -o keymap.c keymap.json
+```
+
+You can add custom C code to the newly generated `keymap.c` file. Do note that you have to use **either** a C file **or** a JSON file - you cannot do both!
+**If a JSON file is present, the C file is ignored.**

+# Halcyon Ferris
+
+![splitkb/halcyon/ferris](https://i.imgur.com/TlgU8iR.png)
+
+The Halcyon Ferris rev1 is the first Ferris revision and the fifth keyboard in our Halcyon range. Similar to Aurora, all keyboards in the series share the same feature set. The key highlights:
+
+- Halcyon keyboards come preassembled! You won't need a soldering iron.
+- You'll be able to install [VIK](https://github.com/sadekbaroudi/vik) modules.
+- It'll come fully documented, which includes the unboxing, assembly (with only a screwdriver), first installation and some advanced use cases.
+- Both the connection to the host device as well as the interconnect between the keyboard halves use USB C.
+- The controller has full ESD protection on all USB C ports, as well as all switch matrix GPIO!
+- The controller is interchangable. If part of your keyboard ever breaks, we can replace just the bits that need replacing.
+
+* Keyboard Maintainer: [splitkb.com](https://github.com/splitkb.com)
+* Hardware Availability: [splitkb.com](https://splitkb.com).
+
+Make example for this keyboard (after setting up your build environment):
+
+ make splitkb/halcyon/ferris/rev1:default
+
+The keyboard can be flashed by copying the resulting `.uf2` file onto the `RPI-RP2` flash drive.
+
+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).
+
+## Bootloader
+
+Enter the bootloader in 3 ways:
+
+* **Reset button**: Double-tap the reset button at the top of the controller, right above the USB-C port.
+* **Bootloader reset**: Hold down the "Boot" button and plug in the keyboard.
+* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available.

+# Halcyon Lily58's Default Keymap
+_This keymap is a copy of the [Lily58 default keymap](https://github.com/qmk/qmk_firmware/tree/master/keyboards/lily58/keymaps/default), with slight modifications._
+
+A simple default keymap for the Halcyon Lily58
+=============================================
+
+Keymaps in general are quite personal, so it is difficult to come up with a default that will suit every user. We hope this keymap serves as a good starting point for your own - although it should be fairly usable out-of-the-box.
+
+What do all these layers do?
+----------------------------
+
+### Layer 0: Base layer
+
+![Layer 0](https://i.imgur.com/sq8Rql7h.png)
+
+This is where your basic letters live.
+
+The homing thumb fingers are used to access the different layers.
+
+* The homing left thumb finger gives access to the Symbols (or lower) layer
+* The homing right thumb finger gives access to the Navigation (or raise) layer
+* Pressing both homing thumb fingers gives access to the Adjust layer
+
+### Layer 1: Lower
+
+![Layer 1](https://i.imgur.com/baSE2OJh.png)
+
+The Lower layer gives access to the F keys on the second row, and shifted number keys on the home row. It also provides some shifted symbol keys.
+
+### Layer 2: Raise
+
+![Layer 2](https://i.imgur.com/CRnDa6Nh.png)
+
+The Raise layer gives access the arrow keys on the right hand, in addition to some unshifted symbols. The left hand provides an alternative set of F keys, while the second row provides an alternative set of number keys.
+
+### Layer 3: Adjust
+
+![Layer 3](https://i.imgur.com/QbCiTcyh.png)
+
+The Adjust layer exposes RGB adjustment keys on the right hand.
+
+Where is the keymap.c?
+----------------------
+
+The keymap.c file is not published to the repository. It is generated from `keymap.json` by the build system.
+
+This avoids duplicating information and allow users to edit their keymap from the QMK Configurator web interface.
+
+How do I edit and update the keymap?
+------------------------------------
+
+The `keymap.json` file is generated from the QMK Configurator interface and formatted for better readability in the context of the Ferris keyboard.
+
+To edit it, you may:
+* Edit it directly from a text editor.
+* Edit it from the QMK Configurator.
+
+If you decide to use the latter workflow, here are the steps to follow:
+
+* From the [QMK Configurator](https://config.qmk.fm/#/splitkb/halcyon/lily58/rev2/LAYOUT), hit the "import QMK keymap json file" button (it has a drawing with an up arrow on it).
+* Browse to the location of your keymap (for example, `<your qmk repo>/keyboards/splitkb/halcyon/lily58/keymaps/default/keymap.json`)
+* Perform any modification to the keymap in the web UI
+* Export the keymap to your downloads folder, by hitting the "Export QMK keymap json file" button (it has a drawing with a down arrow on it)
+* Replace your original keymap with the one you just downloaded
+
+_**Note:** At the time of writing (the 24th of October 2022), not every feature used in the default keymap is supported by the QMK Configurator. You cannot yet upload the default `keymap.json` due to a file format mismatch - use the "Load Default" button to load the default keymap instead. Additionally, custom configuration options are still being worked on: if your keymap depends on them, please compile your firmware offline for now._
+
+I want to do more than the JSON format supports!
+-------------------------------------------------
+
+While the `json` format is easy to use, it does lack certain functionality - most notably custom OLED or encoder behaviour.
+
+To add this, you need to convert it to the `c` format. Do keep in mind that this is generally a one-way operation.
+
+First, from the root of your qmk repo, move to your keymap folder
+
+```bash
+cd ./keyboards/splitkb/halcyon/lily58/keymaps/my_personal_keymap
+```
+
+Next, convert your `keymap.json` to a `keymap.c`
+
+```bash
+qmk json2c -o keymap.c keymap.json
+```
+
+You can add custom C code to the newly generated `keymap.c` file. Do note that you have to use **either** a C file **or** a JSON file - you cannot do both!
+**If a JSON file is present, the C file is ignored.**

+# Halcyon Lily58
+
+![splitkb/halcyon/lily58](https://i.imgur.com/q7VIrbz.png)
+
+The Halcyon Lily58 rev2 is the second Lily58 revision and the fourth keyboard in our Halcyon range. Similar to Aurora, all keyboards in the series share the same feature set. The key highlights:
+
+- Halcyon keyboards come preassembled! You won't need a soldering iron.
+- You'll be able to install [VIK](https://github.com/sadekbaroudi/vik) modules.
+- It'll come fully documented, which includes the unboxing, assembly (with only a screwdriver), first installation and some advanced use cases.
+- Both the connection to the host device as well as the interconnect between the keyboard halves use USB C.
+- The controller has full ESD protection on all USB C ports, as well as all switch matrix GPIO!
+- The controller is interchangable. If part of your keyboard ever breaks, we can replace just the bits that need replacing.
+
+* Keyboard Maintainer: [splitkb.com](https://github.com/splitkb.com)
+* Hardware Availability: [splitkb.com](https://splitkb.com).
+
+Make example for this keyboard (after setting up your build environment):
+
+ make splitkb/halcyon/lily58/rev2:default
+
+The keyboard can be flashed by copying the resulting `.uf2` file onto the `RPI-RP2` flash drive.
+
+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).
+
+## Bootloader
+
+Enter the bootloader in 3 ways:
+
+* **Reset button**: Double-tap the reset button at the top of the controller, right above the USB-C port.
+* **Bootloader reset**: Hold down the "Boot" button and plug in the keyboard.
+* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available.
