+# HHKB Lite 2
+
+![HHKB Lite 2](https://deskthority.net/wiki/images/e/ed/HHKB_Lite_2.jpg)
+
+This is for the [HHKB Lite 2](https://deskthority.net/wiki/HHKB_Lite)
+by PFU, identified by model numbers PD-KB200W/U or PD-KB200B/U. It
+uses the replacement Teensy 2.0 board from [my other
+project](https://github.com/thirteen37/HHKB-Lite-2-Teensy).
+
+Make example for this keyboard (after setting up your build environment):
+
+    make hhkb_lite_2:default
+
+Flashing example for this keyboard:
+
+    make hhkb_lite_2:default:flash
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
+
+## Details
+
+The `default` keymap is nearly the official standard US QWERTY, except
+with the `Delete` key behaving like `BS`, which is as if DIP `SW3` is
+set.
+
+While there are two physical `Fn` keys on the keyboard, they are
+electrically indistinguishable (same wiring matrix) so they can not be
+assigned different keycodes.
