 ## Summary
 
 Often, you may want a certain key position to alter which layers are enabled, change the default layer, etc.
-Some of those behaviors are still in the works; the ones that are working now are documented here.
+Below are the list of behaviors that can be used to activate and deactivate layers.
 
 :::note
-Multiple layers can be active at the same time and activating a layer will not deactivate layers higher up in the "layer stack". See [Layers](../index.mdx#layers) for more information.
+Multiple layers can be active at the same time and activating a layer will not deactivate layers higher up in the "layer stack".
+
+Layer numbers start at 0 following the order they are defined in the keymap node, for example `&mo 3` would activate the 4th layer node defined in the keymap.
+See [Layers](../index.mdx#layers) for more information.

-## Defines to Refer to Layers
-
-When working with layers, you may have several different key positions with bindings that enable/disable those layers.
-To make it easier to refer to those layers in your key bindings, and to change which layers are where later, you can
-add a set of `#define`s at the top of your keymap file, and use those layer in your keymap.
-
-For example, if you have three layers, you can add the following to the top of your keymap:
-
-```dts
-#define DEFAULT 0
-#define LOWER   1
-#define RAISE   2
-```
-
-This allows you to use those defines, e.g. `LOWER` later in your keymap.
