-eekboard - an easy to use virtual keyboard toolkit -*- outline -*-
-
-eekboard is a virtual keyboard software package, including a set of
-tools to implement desktop virtual keyboards.
-
-* Building
-
-** Dependencies
-
-REQUIRED: GLib2, GTK, PangoCairo, libxklavier, libcroco
-OPTIONAL: libXtst, at-spi2-core, IBus, Clutter, Clutter-Gtk, Python, Vala, gobject-introspection, libcanberra
-
-** Build from git repo
-
-  $ git clone git://github.com/ueno/eekboard.git
-  $ cd eekboard
-  $ ./autogen.sh --prefix=/usr --enable-gtk-doc
-  $ make
-  $ sudo make install
-
-** Build from tarball
-
-  $ ./configure --prefix=/usr
-  $ make
-  $ sudo make install
-
-* Running
-
-  $ eekboard
-  $ eekboard -f # show/hide automatically based on focus-in/focus-out events
-
-Even though eekboard -f watches a11y events by default, it currently
-works better with IBus.  To use IBus, do:
-
-  $ gsettings set org.fedorahosted.eekboard focus-listener 'ibus'

+*squeekboard* - a Wayland virtual keyboard
+========================================
+
+*Squeekboard* is a virtual keyboard supporting Wayland, built primarily for the *Librem 5* phone.
+
+Features
+--------
+
+### Present
+
+- GTK3
+- Custom xml-defined keyboards
+- DBus interface to show and hide
+
+### Temporarily dropped
+
+- A settings interface
+
+### TODO
+
+- Use Wayland virtual keyboard protocol
+- Use Wayland text input protocol
+- Use Wayland input method protocol
+- Pick up DBus interface files from /usr/share
+
+Building
+--------
+
+### Dependencies
+
+See `.gitlab-ci.yml`.
+
+### Build from git repo
+
+```
+$ git clone https://source.puri.sm/Librem5/eekboard.git
+$ cd eekboard
+$ mkdir ../build
+$ meson ../build/
+$ cd ../build
+$ ninja install
+```
+
+For development, alter the `meson` call:
+
+```
+$ meson ../build/ --prefix=../install
+```
+
+and don't skip `ninja install` before running. The last step is necessary in order to find the keyboard definition files.
+
+Running
+-------
+
+```
+$ rootston
+$ cd ../build/
+$ src/squeekboard
+```
+
+### Testing
+
+```
+$ busctl call --user sm.puri.OSK0 /sm/puri/OSK0 sm.puri.OSK0 SetVisible b true
+$ busctl call --user sm.puri.OSK0 /sm/puri/OSK0 sm.puri.OSK0 SetVisible b false
+$ gsettings set org.gnome.desktop.input-sources sources "[('xkb', 'us'), ('xkb', 'ua')]"
+$ gsettings set org.gnome.desktop.input-sources current 1

+  <description summary="Protocol for creating input methods">
+    This protocol allows applications to act as input methods for compositors.
+    
+    An input method context is used to manage the state of the input method.
+
+    Text strings are UTF-8 encoded, their indices and lengths are in bytes.
+
+    This document adheres to the RFC 2119 when using words like "must",
+    "should", "may", etc.
+    
+    Warning! The protocol described in this file is experimental and
+    backward incompatible changes may be made. Backward compatible changes
+    may be added together with the corresponding interface version bump.
+    Backward incompatible changes are done by bumping the version number in
+    the protocol and interface names and resetting the interface version.
+    Once the protocol is to be declared stable, the 'z' prefix and the
+    version number in the protocol and interface names are removed and the
+    interface version number is reset.

+      An input method object allows for clients to compose text.
+
+      The objects connects the client to a text input in an application, and
+      lets the client to serve as an input method for a seat.
+
+      The zwp_input_method_v2 object can occupy two distinct states: active and
+      inactive. In the active state, the object is associated to and
+      communicates with a text input. In the inactive state, there is no
+      associated text input, and the only communication is with the compositor.
+      Initially, the input method is in the inactive state.
+
+      Requests issued in the inactive state must be accepted by the compositor.
+      Because of the serial mechanism, and the state reset on activate event,
+      they will not have any effect on the state of the next text input.
+
+      There must be no more than one input method object per seat.

+        implementation-dependent - do not assume that this region will not
+        actually be occluded.
+
+        A positive value is only meaningful if the surface is anchored to an
+        edge, rather than a corner. The zone is the number of surface-local
+        coordinates from the edge that is considered exclusive.
+
+        Surfaces that do not wish to have an exclusive zone may instead specify
+        how they should interact with surfaces that do. If set to zero, the
+        surface indicates that it would like to be moved to avoid occluding
+        surfaces with a positive exclusive zone. If set to -1, the surface
+        indicates that it would not like to be moved to accommodate for other
+        surfaces, and the compositor should extend it all the way to the edges
+        it is anchored to.
+
+        For example, a panel might set its exclusive zone to 10, so that
+        maximized shell surfaces are not shown on top of it. A notification
+        might set its exclusive zone to 0, so that it is moved to avoid
+        occluding the panel, but shell surfaces are shown underneath it. A
+        wallpaper or lock screen might set their exclusive zone to -1, so that
+        they stretch below or over the panel.
