Awesome! This is really valuable.

It does raise a few questions about building a few of the components,
but this is not related to this particular merge.

+• Notes
+
+  - libunity is an independant library which has a client side API for talking
+    to Unity. However it does not depend on the main Unity codebase and the 
+    main Unity codebase does not depend on it.
+
+  - Unity and it's desktop environment modules are all modules of Compiz. We use
+    a patched version of Compiz which uses the GLib main loop instead of the
+    custom Compiz main loop. This allows us to use GNOME libraries easily inside
+    the Unity plugins.
+
+    We are currently working on getting this patch upstreamed, but until then
+    you will need to build this special version of Compiz.
+
+  - libunity is written in Vala and the rest of Unity in C++/C.
+
+  - Unity depends on a library called Nux (lp:nux) which let's us do OpenGL
+    layouts quickly and efficiently.
+
+
+• Dependencies
+
+  These are in Debian package name form, but it should be easy enough to
+  translate them to other systems:
+
+  libglib2.0-dev libgdk-pixbuf2.0-dev libcairo2-dev libpng12-dev libglew1.5-dev
+  libglewmx1.5-dev libxxf86vm-dev libgl1-mesa-dev libsigc++-2.0-dev
+  libpango1.0-dev doxygen cmake pkg-config valac intltool libgee-dev
+  libbamf-dev gsettings-desktop-schemas-dev libgconf2-dev  libglib2.0-dev
+  libdbusmenu-glib-dev libgtk2.0-dev libdee-dev libindicator-dev 
+  libboost-dev libboost-serialization-dev libmetacity-dev python-dev cython
+
+  However, as with any project, it's probably best to just run autogen/cmake
+  and figure out what you need/is missing. If your distro supports grabbing
+  all the packages needed to build a package, then at least do that for
+  Compiz, as I'm not going to detail everything it needs here.
+
+  In case your distro isn't packaging all the Ayatana software, these links
+  might come in handy:
+
+  https://launchpad.net/dee
+  https://launchpad.net/bamf
+  https://launchpad.net/libindicator
+
+  Also, although we don't hard depend on them, having a few indicators installed
+  will make your experience better:
+
+  https://launchpad.net/indicator-appmenu
+  https://launchpad.net/indicator-application
+  https://launchpad.net/indicator-network
+  https://launchpad.net/indicator-sound

+  Logout, login, then in a terminal do
+  
+    $ compiz-unity-setup-env
+    $ compiz --replace cpp &
+    $ ccsm
+
+  And then use the CompizConfig Settings Window to search for and enable the Unity plugin!
