 Keymap framework - how to define your keymap

 ## 0. Keymap and layers
-**Keymap** is comprised of multiple layers of key layout, you can define **32 layers** at most.
-**Layer** is an array of **keycodes** to define **actions** for each physical keys.
-respective layers can be validated simultaneously. Layers are indexed with 0 to 31 and higher layer has precedence.
+In QMK,  **`const uint16_t PROGMEM keymaps[][MATRIX_ROWS][MATRIX_COLS]`** holds multiple **layers** of keymap information in **16 bit** data holding the **action code**. You can define **32 layers** at most.

+For trivial key definitions, the higher 8 bits of the **action code** are all 0 and the lower 8 bits holds the USB HID usage code generated by the key as **keycode**.

 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.

 ### 0.2 Layer Precedence and Transparency
 Note that ***higher layer has higher priority on stack of layers***, namely firmware falls down from top layer to bottom to look up keycode. Once it spots keycode other than **`KC_TRNS`**(transparent) on a layer it stops searching and lower layers aren't referred.
 
-You can place `KC_TRNS` on overlay layer changes just part of layout to fall back on lower or base layer.

+You can place `KC_TRANS` on overlay layer changes just part of layout to fall back on lower or base layer.
+Key with `KC_TRANS` (`KC_TRNS` and `_______` are the alias) doesn't has its own keycode and refers to lower valid layers for keycode, instead.
 See example below.
 
 
 ### 0.3 Keymap Example
-Keymap is **`keymaps[]`** C array in fact and you can define layers in it with **`KEYMAP()`** C macro and keycodes. To use complex actions you need to define `Fn` keycode in **`fn_actions[]`** array.
+Keymap in this QMK is **`static const uint16_t PROGMEM keymaps[]`** C array in fact and you can define layers in it with **`KEYMAP()`** C macro and keycodes. To use complex actions you need to define `Fn` keycode in **`fn_actions[]`** array.  It holds the 16 bit quantum keycode (action code).
+
+> Please note that keymap in the TMK, which QMK was forked from, is **`static const uint8_t PROGMEM keymaps[]`** C array which holds the 8 bit keycode (~USB HID usage code).
 
 This is a keymap example for [HHKB](http://en.wikipedia.org/wiki/Happy_Hacking_Keyboard) keyboard.
-This example has three layers, 'Qwerty' as base layer, 'Cursor' and  'Mousekey'.
+This example has three layers, 'QWERTY' as base layer, 'FN' and  'MOUSE'.
+
 In this example,
 
- `Fn0` is a **momentary layer switching** key, you can use keys on Cursor layer while holding the key.
-
- `Fn1` is a momentary layer switching key with tapping feature, you can get semicolon **';'** with taping the key and switch layers while holding the key. The word **'tap'** or **'tapping'** mean to press and release a key quickly.
-
- `Fn2` is a **toggle layer switch** key, you can stay switched layer after releasing the key unlike momentary switching.
+ `MO(layer)` is a **momentary layer switching** key.
 
 You can find other keymap definitions in file `keymap.c` located on project directories.

 ## 1. Keycode
-See [`common/keycode.h`](../common/keycode.h) or keycode table below for the detail. Keycode is internal **8bit code** to indicate action performed on key in keymap. Keycode has `KC_` prefixed symbol respectively. Most of keycodes like `KC_A` have simple action registers key to host on press and unregister on release, while some of other keycodes has some special actions like `Fn` keys, Media control keys, System control keys and Mousekeys.
+See [`tmk_core/common/keycode.h`](../tmk_core/common/keycode.h) or keycode table below for the detail. Keycode is internal **8bit code** to indicate action performed on key in keymap.  Keycodes are based on [HID Usage Keyboard/Keypad Page(0x07)](http://www.usb.org/developers/hidpage/Hut1_12v2.pdf) plus special codes in the `0xA5-DF` range.

 ### 1.5 Fn key
-`KC_FNnn` are keycodes for `Fn` key which not given any actions at the beginning unlike most of keycodes has its own inborn action. To use these keycodes in `KEYMAP()` you need to assign action you want at first. Action of `Fn` key is defined in `fn_actions[]` and its index of the array is identical with number part of `KC_FNnn`. Thus `KC_FN0` keycode indicates the action defined in first element of the array. ***32 `Fn` keys can be defined at most.***
+You don't need to use this functionality under QMK since this is a backward compatibility functionality.  Unlike TMK, you can write action code itself directly in  **`static const uint16_t PROGMEM keymaps[]`** C array using `MO(layer)`, etc.

 ## 5. Legacy Keymap
-This was used in prior version and still works due to legacy support code in `common/keymap.c`. Legacy keymap doesn't support many of features that new keymap offers. ***It is not recommended to use Legacy Keymap for new project.***

-    #define USE_LEGACY_KEYMAP
+In QMK, `tmk_core/common/keymap.c` is missing and its replacement `quantum/keymap_common.c` lacks Legacy Keymap support.
 
 Legacy Keymap uses two arrays `fn_layer[]` and `fn_keycode[]` to define Fn key. The index of arrays corresponds with postfix number of `Fn` key. Array `fn_layer[]` indicates destination layer to switch and `fn_keycode[]` has keycodes to send when tapping `Fn` key.
 
-In following setting example, `Fn0`, `Fn1` and `Fn2` switch layer to 1, 2 and 2 respectively. `Fn2` registers `Space` key when tapping while `Fn0` and `Fn1` doesn't send any key.
