 Whenever you press a key, the firmware of your keyboard can register this event.
 It can register when the key is pressed, held and released.
 
-This usually happens with a [periodic scan of key presses with a frequency around 100 hz](https://github.com/benblazak/ergodox-firmware/blob/master/references.md#typical-keyboard-information).
-This speed often is limited by the mechanical key response time, the protocol
-to transfer those key presses (here USB HID), and by the software it is used in.

 ## 2. What the Firmware Sends
 
-The [HID specification](http://www.usb.org/developers/hidpage/Hut1_12v2.pdf)
-tells what a keyboard can actually send through USB to have a chance to be
-properly recognised. This includes a pre-defined list of keycodes which are
-simple numbers from `0x00` to `0xE7`. The firmware assigns a keycode to each
-key of the keyboard.

 ## 3. What the Operating System Does
@@ -45,49 +39,31 @@ Once the keycode reaches the operating system, a piece of software has to have
 it match an actual character thanks to a keyboard layout. For example, if your
 layout is set to QWERTY, a sample of the matching table is as follow:
 
-``` text
 | keycode | character |
-|---------+-----------|
-|    0x04 | a/A       |
-|    0x05 | b/B       |

 ## Back to the firmware
 
-As the layout is generally fixed (unless you create your own), the firmware can
-actually call a keycode by its layout name directly to ease things for you.

-QWERTY. The full list can be found in `keycode.txt`.

 ## List of Characters You Can Send

-using a QWERTY UK layout, or a QWERTY US International.

 ## How to (Maybe) Enter Unicode Characters
 
-You can have the firmware send *sequences of keys* to use the [software Unicode
-Input
-Method](https://en.wikipedia.org/wiki/Unicode_input#Hexadecimal_code_input) of
-the target operating system, thus effectively entering characters independently
-of the layout defined in the OS.
