+This keymap is my preferred layout (after a certain amount of experimentation).
+The rationale behind the design is as follows:
+
+I grew up typing from a very early age and thus never learned the "correct" way
+to touch type (essentially, I'm self-taught). As a, result my fingers don't
+tend to stay on the "home keys" and occasionally my right hand wants to type
+keys that are on the left of the keyboard, and vice versa.
+
+Hence, despite liking the idea of split keyboards in principle, I've never been
+able to get on with them because the split simply doesn't work with my style of
+typing. The Ergodox solves this neatly by virtue of having a few extra keys in
+the "middle" of the keyboard which I can utilise for deliberate redundancy.
+Thus in this keymap there are two "6" keys (one on the left, one on the right)
+and likewise Y, H, G, and B are all duplicated to enable one-handed patterns
+that I use frequently (e.g. "byobu" with the right hand, "yes" with the left,
+etc.).
+
+I occasionally use the numeric pad for data entry, thus this is duplicated
+under the natural home position of the right hand in layer 1 (activated by
+holding one of the right thumb buttons), while the cursor keys are duplicated
+under the classic WASD gaming layout of the left hand in layer 2 (activated by
+holding one of the left thumb buttons). Various other useful keys also appear
+in these layers (brackets and symbols for coding in layer 1, navigation and
+F-keys in layer 2, etc.).
+
+Finally, modifier keys like Ctrl, Shift, and Alt, along with Backspace and
+Enter are all in traditional locations in an effort to reuse existing muscle
+memory as much as possible (keys like =, #, and ' are in layer 1). The layout
+maps are in the comments of keymap_dave.c so I won't bother duplicating them
+here.
+
+Oh, and the LEDs are rather pimped ... because I could!
+
+Anyway, although I'm sure this keymap won't be to many people's taste you might
+find some interesting ideas in here for your own layouts. Do tweet me
+(@waveform80) if you have any questions / suggestions / bugs.
+
+Dave.
