+What is Wayland
+
+Wayland is a project to define a protocol for a compositor to talk to
+its clients as well as a library implementation of the protocol. The
+compositor can be a standalone display server running on Linux kernel
+modesetting and evdev input devices, an X applications, or a wayland
+client itself. The clients can be traditional appliactions, X servers
+(rootless or fullscreen) or other display servers.
+
+The wayland protocol is essentially only about input handling and
+buffer management. The compositor receives input events and forwards
+them to the relevant client. The clients creates buffers and renders
+into them and notifies the compositor when it needs to redraw. The
+protocol also handles drag and drop, selections, window management and
+other interactions that must go throught the compositor. However, the
+protocol does not handle rendering, which is one of the features that
+makes wayland so simple. All clients are expected to handle rendering
+themselves, typically through cairo or OpenGL.
+
+The wayland repository includes a compositor and a few clients, but
+both the compositor and clients are essentially test cases.

+Building Instructions
+
+The instructions below assume some familiarity with git and building
+and running experimental software. And be prepared that this project
isn't at all useful right now, it's still very much a prototype. When
the instructions suggest to clone a git repo, you can of course just
add a remote and fetch instead, if you have a clone of that repo
