+# DCompact Layout
+
+**Dvorak, Layered, Mouse-Enabled, Compact**
+
+_See [the layout source](keymap.c) for the actual layout_
+
+## Goals
+
+The following are the goals kept in mind when designing the DCompact
+layout:
+
+- Provide minimal travel distance when typing English or coding
+- Consistent muscle memory translation from standard QWERTY
+- Statless typing experience
+- OS-agnostic features, macros, and key placement
+- Minimize dependence on mouse usage
+
+These are generally all met or balanced within reason. This layout is
+not intended at all to be a familiar layout for much of anyone (except
+maybe those who already type in Dvorak) -- this is meant to amplify the
+best parts of having limited, ortholinear keys with layering.
+
+## As Reference Material
+
+If you're reading this hoping to find reference material to implement
+your own layout, then please feel free to copy over this layout and
+make edits where you see fit. I removed a lot of the features I felt
+extraneous to my usage and simplified style where I felt needed. This
+would hopefully mean that my code should feel like a good base to
+develop from for those new to QMK.
+
+_Remember that settings defined in the layout directory override and
+merge with those in the keyboard folder_
