+# Owodunni planck layout
+
+By Alexander Poole
+
+## Main idea
+
+This is a balanced QWERTY layout that is made for typing and coding.
+It is inspired by [BEAKL-27](https://ieants.cc/beakl/layouts.phpq) for
+the symbol layers. It keeps [colemak-dh](https://colemakmods.github.io/mod-dh/)
+if I ever decide to learn it.
+
+## Build
+
+To build:
+```cli
+qmk compile -kb planck/rev6_drop -km owodunni
+```
+
+Or first configure QMK:
+```cli
+qmk config user.keyboard=planck/rev6_drop
+```
+```cli
+qmk config user.keymap=owodunni
+```
+Then you can compile without flags:
+```cli
+qmk compile
+```
+
+## Swedish keys
+
+To write Swedish use the following keys while using a Swedish keymap:
+
+| SE key | US key |
+|--------|--------|
+| å | [ |
+| ä | ' |
+| ö | ; |
