+# Motform Planck Layout
+
+This layout is based off the [colemak-se](github.com/motform/colemak-se)
+layout and features many tweaks to make working with Emacs and
+evil-mode more ergonomi. As with the colemak layout itself, the idea
+is to concentrate as much movement as possible to the home row.
+
+To properly use the layout in Emacs, set Super to LGUI and Meta to RGUI.
+Unless you are running a permutation of the MacOS Swedish QWERTY-layout,
+modifiers will probably not work. For future develoment, I’m planning
+to add support for MS Windows SE-QWERTY in the form of a secondary layer.
