+# 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
+```
+
+### Letters
+
+```
+a: -^-- --^-
+b: -v-^ ^-v-
+c: -^^^ ^^^-
+d: -vvv vvv-
+e: ---^ ^---
+f: --^v v^--
+g: -^v- -v^-
+h: -vv- -vv-
+i: --^- -^--
+j: -^^v v^^-
+k: -^vv vv^-
+l: -^^- -^^-
+m: -^-^ ^-^-
+n: -v-- --v-
+o: --v- -v--
+p: -v^- -^v-
+q: -^v^ ^v^-
+r: --^^ ^^--
+s: --vv vv--
+t: ---v v---
+u: -v-v v-v-
+v: --v^ ^v--
+w: -v^v v^v-
+x: -vv^ ^vv-
+y: -^-v v-^-
+z: -v^^ ^^v-
+```
+
+### Numbers and Symbols
+
+```
+0: vv-- --vv
+1: vv-v v-vv
+2: vvv- -vvv
+3: v^-- --^v
+4: v^-^ ^-^v
+5: v^^- -^^v
+6: v^-v v-^v
+7: v-v- -v-v
+8: v^^v v^^v
+9: v-^^ ^^-v
+-: v^vv vv^v
+=: vvv^ ^vvv
+[: vv^- -^vv
+]: v-^v v^-v
+\: v^v- -v^v
+;: v^^^ ^^^v
+': vv-^ ^-vv
+,: v-vv vv-v
+.: vv^^ ^^vv
+/: v-^- -^-v
+`: v--^ ^--v
+```
+
+### 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---
