+Let's Split
+======
+
+This readme and most of the code are from https://github.com/ahtn/tmk_keyboard/
+
+Split keyboard firmware for Arduino Pro Micro or other ATmega32u4
+based boards.
+
+Features
+--------
+
+Some features supported by the firmware:
+
+* Either half can connect to the computer via USB, or both halves can be used
+  independently.
+* You only need 3 wires to connect the two halves. Two for VCC and GND and one
+  for serial communication.
+* Optional support for I2C connection between the two halves if for some
+  reason you require a faster connection between the two halves. Note this
+  requires an extra wire between halves and pull-up resistors on the data lines.
+
+Required Hardware
+-----------------
+
+Apart from diodes and key switches for the keyboard matrix in each half, you
+will need:
+
+* 2 Arduino Pro Micro's. You can find theses on aliexpress for ≈3.50USD each.
+* 2 TRS sockets
+* 1 TRS cable.
+
+Alternatively, you can use any sort of cable and socket that has at least 3
+wires. If you want to use I2C to communicate between halves, you will need a
+cable with at least 4 wires and 2x 4.7kΩ pull-up resistors
+
+Optional Hardware
+-----------------
+
+A speaker can be hooked-up to either side to the `5` (`C6`) pin and `GND`, and turned on via `AUDIO_ENABLE`.
+
+Wiring
+------
+
+The 3 wires of the TRS cable need to connect GND, VCC, and digital pin 3 (i.e.
+PD0 on the ATmega32u4) between the two Pro Micros.
+
+Then wire your key matrix to any of the remaining 17 IO pins of the pro micro
+and modify the `matrix.c` accordingly.
+
+The wiring for serial:
+
+![serial wiring](imgs/split-keyboard-serial-schematic.png)
+
+The wiring for i2c:
+
+![i2c wiring](imgs/split-keyboard-i2c-schematic.png)
+
+The pull-up resistors may be placed on either half. It is also possible
+to use 4 resistors and have the pull-ups in both halves, but this is
+unnecessary in simple use cases.
+
+Notes on Software Configuration
+-------------------------------
+
+Configuring the firmware is similar to any other TMK project. One thing
+to note is that `MATIX_ROWS` in `config.h` is the total number of rows between
+the two halves, i.e. if your split keyboard has 4 rows in each half, then
+`MATRIX_ROWS=8`.
+
+Also the current implementation assumes a maximum of 8 columns, but it would
+not be very difficult to adapt it to support more if required.
+
+
+Flashing
+--------
+
+If you define `EE_HANDS` in your `config.h`, you will need to set the
+EEPROM for the left and right halves. The EEPROM is used to store whether the
+half is left handed or right handed. This makes it so that the same firmware
+file will run on both hands instead of having to flash left and right handed
+versions of the firmware to each half. To flash the EEPROM file for the left
+half run:
+```
+make eeprom-left
+```
+and similarly for right half
+```
+make eeprom-right
+```
+
+After you have flashed the EEPROM for the first time, you then need to program
+the flash memory:
+```
+make program
+```
+Note that you need to program both halves, but you have the option of using
+different keymaps for each half. You could program the left half with a QWERTY
+layout and the right half with a Colemak layout. Then if you connect the left
+half to a computer by USB the keyboard will use QWERTY and Colemak when the
+right half is connected.
