+XT to USB keyboard converter
+==============================
+This is a port of TMK's converter/xt_usb to QMK.
+
+This firmware converts XT keyboard protocol to USB.(It supports Scan Code Set 1.)
+
+
+Connect Wires
+-------------
+1. Connect **Vcc** and **GND**.
+2. Connect **Clock** and **Data** line. **Clock** is on `PD1`, **Data** on `PD0` by default. And optionally you can use `PB7` for **Reset**.(Compatible to Soarer's converter) To change pin configuration edit `config.h`.
+3. You need pull-up resistor. **1K-10K Ohm** will be OK.
