+# buffet's planck layout
+
+## Layout
+
+The Layout is based on keychords.
+The general idea is that you're able to type everything with either hand, so that you can alternate between hands as you type.
+
+The keys are in a 2x4 block in the top left and top right respectively (mirrored).
+They have greek letter names (see `keymap.c` for more info).
+
+Thumb added to any key means shift is pressed as well.
+
+`-` means the finger presses nothing.
+`^` means the finger presses the upper row.
+`v` means the finger presses the lower row.
+
+```
+Space:   thumb
+Return:  vvvv  vvvv
+Tab:     vv^v  v^vv
+Bspace:  v--v  v--v
+Esc:     lower pinky and thumb
+```
+

+
+### Modifiers
+
+Modifiers all use the top pinky key, and a combinations of modifiers you want to activate for the next keypress (very similar to how OMS work).
+For the modifiers the top row of keys is used.
+
+```
+Control: Ringfinger
+Shift:   Middlefinger
+Alt:     Indexfinger
+Super:   Thumb
+```
+
+`^--v  v--^` can be used to lock the next modifier input.
+
+### Remaining
+
+These combinations are unused.
+
+```
+v^v^
+v-v^
+v---
+```
