+# NAME
+
+wvkbd - on-screen virtual keyboard for wayland compositors using wlroots
+
+# SYNOPSIS
+
+wvkbd-mobintl [OPTIONS]...
+
+*NOTE*: Your binary may have a different suffix depending on which layout you compiled.
+
+# DESCRIPTION
+
+This project aims to deliver a minimal but practically usable implementation of
+a wlroots on-screen keyboard in legible C. This will _only_ be a keyboard, not
+a feedback buzzer, led blinker, or anything that requires more than what's
+needed to input text quickly. The end product should be a static codebase that
+can be patched to add new features.
+
+## OPTIONS
+
+*-D*
+	enable debug mode.
+
+*-o*
+	print pressed keys to standard output.
+
+*-O*
+	print intersected keys to standard output.
+
+*-l* _layers_
+	comma separated list of layers in vertical/portrait mode.
+
+*--landscape-layers* _layers_
+	comma separated list of layers used in horizontal/landscape mode.
+
+*--list-layers*
+	prints a list of all available layers.
+
+*-H* _pixels_
+	Height of the keyboard in pixels, for vertical/portrait mode.
+
+*-L* _pixels_
+	Height of the keyboard in pixels, for horizontal/landscape mode
+
+*--fn* _font_
+	set font and size (e.g. DejaVu Sans 20)
+
+*--hidden*
+	Start hidden (send SIGUSR2 to show).
+
+*--alpha* _int_
+	Set alpha value (i.e. transparency) for all colors [0-255]
+	
+*--bg* _rrggbb|aa_ 
+	Set color of background
+
+*--fg* _rrggbb|aa_       
+	Set color of keys
+
+*--fg-sp* _rrggbb|aa_       
+	Set color of special keys
+
+*--press* _rrggbb|aa_       
+	Set color of pressed keys
+
+*--press-sp* _rrggbb|aa_       
+	Set color of pressed special keys
+
+*--swipe* _rrggbb|aa_       
+	Set color of swiped keys
+
+*--swipe-sp* _rrggbb|aa_       
+	Set color of swiped special keys
+
+*--text* _rrggbb|aa_       
+	Set color text on keys
+
+*--text-sp* _rrggbb|aa_       
+	Set color text on special keys
+
+*--version*
+	Print version information
+
+*-h*, *--help*
+	Print usage help 
+
+
+# SIGNALS
+
+You can send signals to wvkbd to hide/show it (e.g. using _kill_(1) with _-s_):
+
+*SIGUSR1*
+	Hide the keyboard.
+
+*SIGUSR2*
+	Show the keyboard
+
+*SIGRTMIN*
+	Toggle visibility
+
+# COMPOSE BUTTON
+
+The default mobile international layout features a Compose button (*Cmp*)
+which, when combined with another key, opens up a layout that offers variants
+for that key. This is similar to functionality that other keyboards implemented
+using a *long press* (wvkbd has no such notion, holding a key will repeat
+it like on a physical keyboard).
+
+For example, press Cmp + a to access variants with diacritics like á,à,â,ä, etc.. 
+
+Most layouts also feature the following that are less obvious:
+
+- Press Cmp and . to access more punctuation
+- Press Cmp and - or , to access 'mathematical' symbols (+,-,=,etc)
+- Press Cmp and ' or 0 or 9 to access more brackets and quotes
+- Press Cmp and q to access emojis
+
+Last, but not least, pressing Cmp + space or Cmp + ⌨  or Cmp + Abc opens up an
+index that allows you to immediately jump to any layout by name, even layouts
+not explicitly added to your layers on startup.
