+# 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.
