+ * This is Mitch's default ACR60 layout (also DZ60, on which the ACR60 is based). This is a
+ * Mac-oriented layout, as noted by the GUI keys immediately next to the space bar area of the
+ * lower modifier row. This uses the MITCHSPLIT keymap as defined in arc60.h, which uses a
+ * 3-split space bar and a split right shift. Otherwise it's a standard 60% layout (for now).
+ *
+ * For me, this is a great place to start getting used to a split key setup and still mostly
+ * sticking to a standard staggered 60% layout so my entire game isn't thrown off.
+ *
+ * Layers (0-based index because we're devs!):
+ *
+ *    0: Default QWERTY layer
+ *      Note Fn and Alt keys on the right side of the spacebar, not sure if those are
+ *      normal position but that's what I'm used to at this point. YMMV
+ *
+ *    1: Function Layer
+ *      Function keys, Grave Key, Delete, Caps lock on the tab, media keys, and directional
+ *      keys. Also you can hit the Alt key position to switch (and lock) into the 3rd layer
+ *      if you really want to mess with your SFX for a bit.
+ *
+ *    2: Special Effects Layer
+ *      RGB and backlight settings access. RGB cycle on "S" key position and if locked into
+ *      the third layer you can hold shift to cycle backwards (see notes below). Bootloader
+ *      access is on this layer. If layer locked, hit right Alt key to get back to layer 0.
+ *
+ * The keymap layer definitions below look pretty bad when soft-wrapped by your IDE / text editor.
+ * Be sure to disable wrapping to make things more readable with lines preserved.
