+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.
 
-At the moment work still needs to be done to make the keyboard fully functional
-and determine a minimum feature set. As of now, the following works:
-
 ## Features
 
  - Typing, modifier locking, layout switching
  - Positive visual feedback on key presses
- - Custom layouts
+ - Custom layouts and underlying keymaps
+ - On-the-fly layout and keymap switching
  - Custom color schemes
+ - Proper font drawing
+ - Intuitive layouts
+ - International layouts (cyrillic, arabic)
+ - Support for 'Copy' keys which are not on the keymap
+ - Emoji support
+ - Compose key for character variants (e.g. diacritics)
+ - Show/hide keyboard on signals (SIGUSR1 = hide, SIGUSR2 = show)
+ - Automatic portrait/landscape detection and subsequent layout switching
 
-There are some relatively critical areas that still need work:
 
- - Proper drawing of font glyphs/fontconfig alternatives (unknown glyphs for the
+<img src="https://raw.githubusercontent.com/proycon/wvkbd/master/contrib/wvkbd-mobintl-landscape.jpg" width=640 />
-   configured font are not drawn)
+
+There are some areas that still need work:
+
  - Make sure the virtual input method in wayland is working as best as it can
- - Customize keyboard window docking
- - Nicer layout drawing/padding
- - Determine if some dependencies are really needed (fontconfig is VERY
-   annoying, and wld may not be strictly necessary)
-
-And some nice to haves:
-
- - Daemon mode (hide/show keyboard on signals)
  - Support for input method protocol in wayland, ability to respond to text
    fields
- - Alt input modes for things like emojis
- - Typical international layouts in the repository
-
-Of course there's probably some more I'm forgetting, everything here is very
-much early WIP so things will change very quickly.
 
 ## Install
 
 You'll need the following developer packages
 
- - fontconfig
+ - pangocairo
  - wayland-client
  - xkbcommon
- - pixman
 
-After cloning this repo, run `git submodule update --init --recursive`
+Make any customizations you would like in `config.def.h` and run `make`
 
-Make any customizations you would like in `config.h` and run `make`, then `./wvkbd`
+The default set of layouts is called `mobintl` *(mobile international)*, which groups various layouts aimed at mobile devices
+and also attempts to accommodate various international users. The resulting binary is called `wvkbd-mobintl`.
+
+You can, however, define your own layouts by copying and and modifying `layout.mobintl.h` and `keymap.mobintl.h`
+(replace `mobintl` for something like `yourlayout`). Then make your layout set using `make LAYOUT=yourlayout`, and
+the resulting binary will be `wvkbd-yourlayout`
+
+## Usage
+
+Run `wvkbd-mobintl` (or the binary for your custom layout set).
+
+You can switch between the layouts/layers of the keyboard by pressing the Abc/Sym key in the bottom-left. If you only
+want a subset of the available layers, you can define which wants you want and in what order you want to cycle through
+them using the `-l` parameter. This takes takes a ordered comma separated list of
+layout names that are defined in your layout set.
+
+The keyboard can be hidden by sending it a `SIGUSR1` signal and shown again by sending it `SIGUSR2`. This saves some
+start up time and may be appropriate in some low-resource environments.
+
+Wvkbd has an output mode `-o` that will echo its output to standard output. This facility can be used if users want
+audio/haptic feedback, a feature explicitly out of scope for wvkbd. To achieve this, simply pipe wvkbd's output through the external tool
+[clickclack](https://git.sr.ht/~proycon/clickclack):
+
+`$ wvkbd-mobileintl -l simple,special,emoji -o | clickclack -V -f keypress.wav`

 For code contributions, all I ask for now is you run `make format` (requires
 `clang-format`) before opening a PR and include as much relevant detail as
