+# The extra special ergodox build for MacOS Sierra caps lock users
+
+###Do you
+- Hate the OSX / MacOS caps lock delay?
+- Have an ergodox?
+
+###Then this might just be for you!
+
+[This](http://apple.stackexchange.com/questions/81234/how-to-remove-caps-lock-delay-on-apple-macbook-pro-aluminum-keyboard)
+and [this](http://sleepycow.org/2014/07/removing-the-caps-lock-delay-on-a-macbook/)
+are good workarounds for the caps lock delay, however none of these
+work on Sierra.  This abomination of a keymap simulates capslock to the best
+of its abilities.
+This means that it keeps track of caps lock state internally rather than
+sending a caps lock keypress to the OS.  It is smart enough to check for
+modifiers, such as Control being held down, and stop it with the hanky panky
+and just send on the key event unmolested even if FakeCaps is enabled.  And
+since the macro isn't even registered on the non-alphas, it will not affect
+them regardless.  Only in the event that FakeCaps is enabled and an alpha key
+is pressed will it sneak in a shift keydown before the alpha keydown and
+immediately afterward sneaks in a shift keyup.  Generally this works well,
+however there is one known issue:
+
+- Holding down a key will only have the first character in caps.  For instance,
+  with caps lock on, if you hold down the 'a' key, you get:
+
+  ```
+  Aaaaaaaaaaaaaaaaaa
+  ```
+
+I have only tested this on an original Ergodox with a Teensy 2.0.
+
+####Some other small tweaks
+ - Layer 0 board light is off
+ - Layer 1 board light is on solid
+ - Layer 2 board light blinks at speed controlled by BLINK_BASE
