- If the keyboard has multiple electrical/switch layouts:
- include a `LAYOUT_all` which specifies all possible layout positions in the electrical matrix
- use alternate layout names for all other possible layouts, preferring community layout names if an equivalent is available (e.g. `LAYOUT_tkl_ansi`, `LAYOUT_ortho_4x4` etc.)
- Microcontroller and bootloader
- Diode Direction (if not using direct pins)
- the following are required to be configured in `info.json` if necessary
- Direct pin configuration
- Backlight Configuration (where applicable)
- Split keyboard configuration (where applicable)
- Encoder Configuration
- Bootmagic Configuration
- LED Indicator Configuration
- `readme.md`
- standard template should be present -- [link to template](https://github.com/qmk/qmk_firmware/blob/master/data/templates/keyboard/readme.md)
- must follow the [template](https://github.com/qmk/qmk_firmware/blob/master/data/templates/keyboard/readme.md)
- flash command is present, and has `:flash` at end
- valid hardware availability link (unless handwired) -- private groupbuys are okay, but one-off prototypes will be questioned. If open-source, a link to files should be provided.
- clear instructions on how to reset the board into bootloader mode
- a picture about the keyboard and preferably about the PCB, too
- images are not to be placed in the `qmk_firmware` repository
- images should be uploaded to an external image hosting service, such as [imgur](https://imgur.com/).
- if imgur is used, images should be resized appropriately: append "h" to the image url i.e. `https://i.imgur.com/vqgE7Ok.jpg` becomes `https://i.imgur.com/vqgE7Okh.jpg`
- if imgur is used, images should be resized appropriately: append "h" to the image url i.e. [https://i.imgur.com/vqgE7Ok.jpg](https://i.imgur.com/vqgE7Ok.jpg) becomes [https://i.imgur.com/vqgE7Ok**h**.jpg](https://i.imgur.com/vqgE7Okh.jpg)
- image links should link directly to the image, not a "preview" -- i.e. [https://imgur.com/vqgE7Ok](https://imgur.com/vqgE7Ok) should be [https://i.imgur.com/vqgE7Okh.jpg](https://i.imgur.com/vqgE7Okh.jpg) when using imgur
- `rules.mk`
- removed `MIDI_ENABLE`, `FAUXCLICKY_ENABLE` and `HD44780_ENABLE`
- modified `# Enable Bluetooth with the Adafruit EZ-Key HID` -> `# Enable Bluetooth`
- don't repeat `MANUFACTURER` in the `PRODUCT` value
- no `#define DESCRIPTION`
- no Magic Key Options, MIDI Options or HD44780 configuration
- user preference configurable `#define`s need to be moved to keymap `config.h`
- "`DEBOUNCE`" instead of "`DEBOUNCING_DELAY`"
- default values should not be redefined, such as `DEBOUNCE`, RGB related settings, etc.
- feature specific documentation contains most default values
- `grep` or alternative tool can be used to search for default values in core directories (e.g. `grep -r "define DEBOUNCE" quantum`)
- no copy/pasted comment blocks explaining a feature and/or its caveats -- this is what the docs are for
- `Force NKRO to be enabled ... toggled again during a power-up`
- commented-out unused defines, such as RGB effects
- no `#include "config_common.h`
- no `#define MATRIX_ROWS/COLS`, unless necessary (e.g. a keyboard with a custom matrix)
- bare minimum required code for a board to boot into QMK should be present
- initialisation code for the matrix and critical devices
- mirroring existing functionality of a commercial board (like custom keycodes and special animations etc.) should be handled through non-`default` keymaps
- `matrix_init_board()` etc. migrated to `keyboard_pre_init_kb()`, see: [keyboard_pre_init*](custom_quantum_functions.md?id=keyboard_pre_init_-function-documentation)
- prefer `CUSTOM_MATRIX = lite` if custom matrix used, allows for standard debounce, see [custom matrix 'lite'](custom_matrix.md?id=lite)
- prefer LED indicator [Configuration Options](feature_led_indicators.md?id=configuration-options) to custom `led_update_*()` implementations where possible
- Encoder support should not require any keyboard-level code, and associated keymaps should now leverage the [Encoder Map](feature_encoders.md?id=encoder-map) feature instead.
- hardware that's enabled at the keyboard level and requires configuration such as OLED displays or encoders should have basic functionality implemented here
- `<keyboard>.h`
- `#include "quantum.h"` appears at the top
- `LAYOUT` macros should be moved to `info.json`
- keymap `config.h`
- no duplication of `rules.mk` or `config.h` from keyboard
- `keymaps/default/keymap.c`
- `QMKBEST`/`QMKURL` removed
- if using `MO(_LOWER)` and `MO(_RAISE)` keycodes or equivalent, and the keymap has an adjust layer when holding both keys -- if the keymap has no "direct-to-adjust" keycode (such as `MO(_ADJUST)`) then you should prefer to write...
...instead of manually handling `layer_on()`, `update_tri_layer()` inside the keymap's `process_record_user()`.
- `QMKBEST`/`QMKURL` example macros removed
- if using `MO(1)` and `MO(2)` keycodes together to access a third layer, the [Tri Layer](https://docs.qmk.fm/#/feature_tri_layer) feature should be used, rather than manually implementing this using `layer_on/off()` and `update_tri_layer()` functions in the keymap's `process_record_user()`.
- default (and via) keymaps should be "pristine"
- bare minimum to be used as a "clean slate" for another user to develop their own user-specific keymap
- standard layouts preferred in these keymaps, if possible
- should use [encoder map feature](https://docs.qmk.fm/#/feature_encoders?id=encoder-map), rather than `encoder_update_user()`
- default keymap should not enable VIA -- the VIA integration documentation requires a keymap called `via`
- submitters can have a personal (or bells-and-whistles) keymap showcasing capabilities in the same PR but it shouldn't be embedded in the 'default' keymap
- submitters can also have a "manufacturer-matching" keymap that mirrors existing functionality of the commercial product, if porting an existing board
- Do not include VIA json files in the PR. These do not belong in the QMK repository as they are not used by QMK firmware -- they belong in the [VIA Keyboard Repo](https://github.com/the-via/keyboards)
- Do not include KLE json files in the PR. These have no use within QMK.
- Do not include source files from another keyboard or vendors keyboard folder. Including core files is fine.
- For instance, only `wilba_tech` boards shall include `keyboards/wilba_tech/wt_main.c` and `keyboards/wilba_tech/wt_rgb_backlight.c`. But including `drivers/sensors/pmw3360.c` is absolutely fine for any and all boards.
- For instance, only `wilba_tech` boards shall include `keyboards/wilba_tech/wt_main.c` and `keyboards/wilba_tech/wt_rgb_backlight.c`. But including `drivers/sensors/pmw3360.c` is absolutely fine for any and all boards that require it.
- Code that needs to be used by multiple boards is a candidate for core code changes, and should be separated out.
