+# Belak's Ergodox Layout
+
+This has been based off of [emacs\_osx\_dk](https://github.com/jackhumbert/qmk_firmware/tree/master/keyboards/ergodox/keymaps/emacs_osx_dk)
+from the main qmk repo. However, I've taken some of the ideas for the thumbs
+from [dvorak\_emacs](https://github.com/jackhumbert/qmk_firmware/tree/master/keyboards/ergodox/keymaps/dvorak_emacs)
+and tweaked it a bit based on the keycaps I have.
+
+This keyboard is intended for use in emacs (one of the main reasons for easy
+access to modifiers) but it could be useful in other instances as well.
+
+The main repo is used as a testbed, so sometimes the layout may be in a strange
+state. The qmk version should be relatively stable.
+
+## Instructions
+
+This is currently being used on a regular ergodox, but it should work fine on
+the infinity as well. Though, you may have to modify the commands to build and
+flash the firmware to match the separate halves as defined in the infinity
+documentation.
+
+If you are using this keymap in the qmk repo, you should be able to just run
+`make ergodox-belak-teensy`. If you're using this externally (I sometimes make
+changes before syncing them to qmk), use the following instructions:
+
+1. Clone the main qmk repo
+2. Clone this to `$QMK/keyboards/ergodox/keymaps/belak-external`
+3. Run `make ergodox-belak-external-teensy` from the root of the qmk repo.
+
+## Changelog
+
+Fifth Revision
+
+* Change layer keys to tap-dance keys which cycle through additional layers
+* Add a few emoji keys (in preparation for an emoji layer)
+
+Fourth Revision
+
+* Remove media layer
+* Add a layer which swaps control and gui on the thumb keys.
+* Add some basic code to save settings to the eeprom
+* Save the state of the keys swapped in the thumb in the eeprom
+
+Third Revision
+
+* Add numpad layer and remove numpad from symbols layer
+* Disable media layer
+* Add arrow keys on ijkl to the symbols layer
+* Replace ALT on held enter and held delete with GUI (for better OSX
+  compatibility, as there's already an ALT key relatively close)
+* Replace keys above enter and delete with temporary layer switch buttons not
+  matching the other layer switch for that hand.
+* Reindent and space out most of the layer definitions
+
+Second Revision
+
+* Clean up definitions to make differences between layers easier to see
+* Remove old LCD code
+* Add new LCD code based on fredizzimo's branch
+
+First Revision
+
+* Reverse grave and escape
+
+Initial Version
+
+* Copy from emacs\_osx\_dk
+* "Fix" right alt
+* Change thumb keys to match default layout (backspace, delete, enter, space)
+* Add modifiers to thumb keys (ctrl to backspace and space, alt to delete and
+  enter)
+* Replace the RAlt below the brackets with LGui and RGui
+* Remove LCtrl and RCtrl from the keys above shift
+* Add browser forward, and move browser back
+* "Fix" the order of volume keys
+
+## Repository
+
+The original code for this is kept at https://github.com/belak/ergodox-layout and
+is synced to qmk every few main revisions.
