Since QMK is based on TMK and uses major portion of TMK code as is, understanding the essential changes made should help you understand the code.

* **`default_layer_state`** indicates a base keymap layer(0-31) which is always valid and to be referred.
* **`layer_state`** () has current on/off status of the layer on its each bit.
Keymap has its state in two parameter**`default_layer`** indicates a base keymap layer(0-31) which is always valid and to be referred, **`keymap_stat`** is 16bit variable which has current on/off status of layers on its each bit.

Keymap layer '0' is usually `default_layer` and which is the only valid layer and other layers is initially off after boot up firmware, though, you can configured them in `config.h`.
To change `default_layer` will be useful when you switch key layout completely, say you want Colmak instead of Qwerty.
