+# The Impossible Layout
+
+The Impossible Layout is named such because it manages to fit in both a numpad and an inverted-T arrow cluster into the same layer as the alpha keys.
+
+## Main layout
+
+The Impossible Layout places the middle column of the alphas onto where the punctuation keys were, moving he most used punctuation to be accessed by the thumbs. Because removing the middle columns fits with the Workman layout's philosopy, Workman is used as the basis for the layout. This means the layout should be very easy to learn for Workman users, and reasonable for Colemak users. Other space gains are made by combining keys that are only ever chorded with other non symbol keys (with function-layer alternatives where needed).

+## Stenography
+
+The Steno/Plover layer moves the number row below the regular keys, providing a much more comfortable placement for the thumb keys. Using this layout will require a slightly different dictionary to account for different keys being adjacent to the number row.
