+Jeremy's Atreus Key Mapping
+===========================
+
+I am a programmer by trade that suffers from the beginning stages of RSI. As a programmer I use letters, symbols and cursor navigation most often. To prevent strange finger gymnastics, I wrote a script to rank which non-letter characters occurred in my primary source projects most often and then placed these characters in the easiest to reach locations, for me. I made heavy use of momentary layer toggling.
+
+My layout is also geared toward a software based Colemak mapping. I would like it to be hardware, but I use my Laptop on the go frequently and thus my laptop keyboard. I have moved the keycaps to reflect the Colemak layout. My laptop is a MacBook Pro (2015).
+
+## Main Layers
+
+1. [Letters](http://www.keyboard-layout-editor.com/#/gists/6861cb9df09ce78efaddf8aa7471e3ac)
+2. [Symbols](http://www.keyboard-layout-editor.com/#/gists/8956a18b508a78e93b9c38ec3fcccaa5)
+3. [Navigation](http://www.keyboard-layout-editor.com/#/gists/6ed492b714a7f54eb1c5de09b87fd8c4)
+4. [Numbers](http://www.keyboard-layout-editor.com/#/gists/399ceb5624e8388e48a3a5eacac8e973)
+5. [Function Keys](http://www.keyboard-layout-editor.com/#/gists/7fd7dc24c7048316f3724b1893c64e89)
+
+## Notes
+
+### General
+
+Some characters can be accessed multiple ways. This was done because you may be in a given layer, such as numbers, where when doing math, you may need quick access to the parentheses characters for grouping. This prevents some layer switching.
+
+I own an ErgoDox and plan on porting this as a base layer, then using the extra keys the ErgoDox provides accordingly. My goal, though, is to be fully functional on this base setup and build everything into muscle memory.
+
+### Symbol Layer
+
+1. I placed characters that deal with an if statement close together, such as !, & and |.
+2. All matching brace/bracket characters are together as well.
+
+### Number Layer
+
+1. Everything I did was a compromise when trying to mimic a ten-key. I did the best I could.
+2. Operators are duplicated on the right and left. I do not find it comfortable to use my pinky much, so I tend to use my left hand for +, -, * and / but those were also placed on the right hand to mimic the ten-key.
+3. Parentheses were added for typing on the calculator.
+
+### Cursor Layer
+
+1. It includes basic audio controls because they didn't really fit anywhere else
+2. It contains basic file manipulation. I'm not sure that was a good idea. I do save all the time, but Cmd+S isn't exactly hard.
+3. It contains the backspace and delete keys right on top of the left and right arrows.
+4. Cmd and Opt keys are duplicated. This makes for very easy navigation, for example on a Mac, Opt+Left/Right moves word by word. It also backspaces or deletes word by word.
+
+### Function Layer
+
+1. Almost all other layers I saw grouped the F keys into a bunch of three. This only gives nine function keys in order if you attempt to stay as close to the home row as possible. I went with a group of four, which gives all twelve function keys to the right hand, one row below and above the home row.
+2. I duplicated the Command and Option keys the same as on the cursor layer. This makes it dead easy to hit modified function keys such as Cmd+Opt+F5. It's also easy to toss in a Shift modifier in there with the right thumb since the bottom row is preserved.

+The kastyle keymap was originally intended to remap the ErgoDox EZ to more
+closely approximate the layout of a Kinesis Advantage. Notable changes
+over the stock ErgoDox layout include:
+
+  * Re-arragnement of tab, enter, space, and delete to match the Kinesis
+  * Addition of print screen, pause, etc. keys following the kines-ish keymap
+  on L1
+  * GUI keys have replaced Ctrl on the thumb keys (for Mac use), and Alt keys
+  are mapped to allow Esc on tap (good for Vi users)
+  * Most notably, the addition of a momentary one-handed mode for quick and
+  easy access to keys on the other half of the keyboard, e.g. while using a 
+  mouse in one hand, one may add text to a dialogue box with the other without
+  having to reach across the keyboard or remove one's hand from the mouse.

+# Ergodox EZ for OS X
+
+This keymapping is designed to be reasonably familiar to an ordinary Mac keyboard while taking advantage of the Ergodox EZ's features. Caps lock instead enables a layer which allows a user to use HJKL as arrow keys and to control media. Shift and control have additional mappings on S and D to provide easier access while holding down caps lock. 
+
+If you choose to compile this yourself, be sure to compile with `#define PREVENT_STUCK_MODIFIERS` in your `config.h`. Firmware built using [qmk_firmware](https://github.com/jackhumbert/qmk_firmware/).
