 - `#include QMK_KEYBOARD_H` preferred to including specific board files
 - prefer layer enums to #defines
 - custom keycode enums must have first entry = `QK_USER`
 - some care with spacing (e.g., alignment on commas or first char of keycodes) makes for a much nicer-looking keymap. Spaces are preferred to tabs

 - `keymaps/default/keymap.c`
     - `QMKBEST`/`QMKURL` example macros removed
     - if using `MO(1)` and `MO(2)` keycodes together to access a third layer, the [Tri Layer](features/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"
+- default keymaps should be "pristine"
     - bare minimum to be used as a "clean slate" for another user to develop their own user-specific keymap
     - what does pristine mean? no custom keycodes. no advanced features like tap dance or macros. basic mod taps and home row mods would be acceptable where their use is necessary
     - standard layouts preferred in these keymaps, if possible
     - should use [encoder map feature](features/encoders#encoder-map), rather than `encoder_update_user()`
-    - default keymap should not enable VIA -- the VIA integration documentation requires a keymap called `via`
+    - default keymap should not enable VIA -- keymaps targeting VIA support should be submitted to the [VIA QMK Userspace](https://github.com/the-via/qmk_userspace_via) repository
 - submitters can add an example (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)

 - all core PRs must now target `develop` branch, which will subsequently be merged back to `master` on the breaking changes timeline
 - as indicated above, the smallest set of changes to core components should be included in each PR
     - PRs containing multiple areas of change will be asked to be split up and raised separately

         - keymap modifications for anything other than the default-like keymaps **should not be included in the initial PR** in order to simplify the review process
         - the core PR submitter should submit a followup PR affecting other keymaps after initial PR merge
         - large-scale refactoring or consolidation PRs that affect other keymaps (such as renaming keycodes) should always be raised separately
