@ -31,6 +31,20 @@ The reason for this, is that `<name>.h` won't be added in time to add settings (
So you should use the `config.h` for QMK settings, and the `<name>.h` file for user or keymap specific settings.
`/users/<name>/rules.mk` will be included in the build _after_ the `rules.mk` from your keymap. This allows you to have features in your userspace `rules.mk` that depend on individual QMK features that may or may not be available on a specific keyboard. For example, if you have RGB control features shared between all your keyboards that support RGB lighting, you can `define RGB_ENABLE` in your keymap `rules.mk` and then check for the variable in your userspace `rules.mk` like this:
```make
ifdef RGB_ENABLE
# Include my fancy rgb functions source here
endif
```
Because of this, any time you turn on QMK features in your `users/<name>/rules.mk`, you should conditionally enable them only if the flag isn't already defined, like this:
```make
ifndef TAP_DANCE_ENABLE
TAP_DANCE_ENABLE = yes
endif
```
This will ensure that you can explicitly turn off features for an individual keymap.
