             - 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

     - 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/).

     - 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

         - 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...
-        ```
-        layer_state_t layer_state_set_user(layer_state_t state) {
-          return update_tri_layer_state(state, _LOWER, _RAISE, _ADJUST);
-        }
-        ```
-        ...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.

   - Code that needs to be used by multiple boards is a candidate for core code changes, and should be separated out.
