-*** General Principles
-
-    - Use layers instead of reaching.
-    - Use both hands instead of contortions.
-    - Use the home positions as much as possible.
-    - Make full use of the thumbs.
-    - Avoid unnecessary complication.
-
-
-*** Specifics
-
-    - 5 columns, 3 rows, 3 thumb keys, 2 hands.
-    - Can be used on almost any split or non-split ergo or ortho keyboard.
-    - Includes all keys found on a US layout TKL keyboard, plus media keys and
-      mouse emulation.
-    - Home row is the middle row, home thumb key is the middle thumb key.
-    - Maximum 1-u movement from home position for fingers and thumbs, and only
-      along one axis (except for the inner index finger column which is
-      deprioritised compared with the home columns).
-    - Dual-function modifiers on home row, mirrored on both hands.
-    - Dual-function layer change on thumbs.
-    - Layers are designed orthogonally with a single purpose per hand and are
-      accessed by holding a thumb key on the opposite hand.
-    - All layers on the same hand are based on the same basic key arrangement.
-    - Holding layer change and modifiers on one hand combined with a single key
-      press on the other hand can produce any combination of modifiers and
-      single keys without any finger contortions.
-    - Single function mods are also defined on layers on the same hand as the
-      layer change thumb key so layer change and mods can be held in any order
-      or simultaneously without race conditions.
-    - As mods are only enabled on the opposite hand, auto-repeat is available on
-      the home row on layers for use with cursor and mouse keys.
-    - Tap-hold auto-repeat is disabled to permit faster tap-hold switching on
-      thumbs, but thumb tap keys are mirrored onto some layers for use with
-      auto-repeat.  On other layers thumb keys are redefined with important
-      functions for that layer.
