+By setting `RGB_MATRIX_CUSTOM_USER = yes` in `rules.mk`, new effects can be defined directly from your keymap or userspace, without having to edit any QMK core files.
 
-To declare new effects, create a new `rgb_matrix_user/kb.inc` that looks something like this:
+To declare new effects, create a `rgb_matrix_user.inc` file in the user keymap directory or userspace folder.
 
-`rgb_matrix_user.inc` should go in the root of the keymap directory.
-`rgb_matrix_kb.inc` should go in the root of the keyboard directory.
+?> Hardware maintainers who want to limit custom effects to a specific keyboard can create a `rgb_matrix_kb.inc` file in the root of the keyboard directory, and add `RGB_MATRIX_CUSTOM_KB = yes` to the keyboard level `rules.mk`.
