 ## Overview 
-The alphanumeric characters and symbols are spread between three main 'typing' layers: REGULAR, NUMPAD, and SYMBOLS.

 A fourth layer, NAVIGATION, contains useful modifiers, shortcuts, and navigation functions like the arrow keys and page up/down. This layer also provides access to the `ENTER` and `ESC` keys.

-#### SYMBOLS
-This layer holds all the symbols that are not accessible from the REGULAR layer. There is some redundancy (for instance, `/` exists in both the REGULAR and SYMBOLS layer; its position, however, remains consistent) but with the exception of single and double quotes, all symbols are available from this layer.

 #### NAVIGATION
-The primary function of this layer is to provide arrow keys under hjkl. The surrounding keys contain similar functionality - for instance, the keys directly below `DOWN` and `UP` are `PAGEDOWN` and `PAGEUP`, respectively. `HOME` and `END` are inverted from this convention, simply because I kept hitting the wrong key when trying to jump to the beginning/end of lines when editing text.
+Over time, this layer has become a general utility layer, though its primary function of is still to provide arrow keys under hjkl. The surrounding keys contain similar functionality - for instance, the keys directly below `DOWN` and `UP` are `PAGEDOWN` and `PAGEUP`, respectively. `HOME` and `END` are inverted from this convention, simply because I kept hitting the wrong key when trying to jump to the beginning/end of lines when editing text.
 
 To the immediate right of the NAVIGATION layer key are the following modifiers: `SHIFT`, `CONTROL`, `ALT`, `GUI`. All modifiers are the "left" variants. The idea is to use the left hand to hold different modifiers as necessary while using the right hand to navigate and format.
 
-`ESCAPE` is located on the spacebar from this layer, and `DELETE` is placed next to `BACKSPACE`, for convenience when formatting text. There are also four Windows shortcuts for undo, cut, copy, and paste, located in the same position as the relevant keys on the base layer (undo, for example, is in the same place as the `Z` key).

 #### SETTINGS
-Right now, this is pretty similar to the default settings layer (the planck's ADJUST layer).
+The SETTINGS layer can be accessed by pressing both SYMBOL layer keys at once. This is functionally the same as a trilayer, though because both keys are activating the same layer it doesn't actually use the trilayer feature.
 
-Primary differences are the inclusion of an autoshift toggle and the removal of the reset button. The bootloader functionality has been moved to a leader key sequence: LEAD - R - E - S - E - T.
+This layer contains things like feature toggles, media controls, and other infrequently-used options. 
 
 ### Leader Key Sequences
