 Installation
 ============
 
-See the file 'INSTALL'. If you are not using a released version of
-gnome-desktop (for example, if you checked out the code from git), you
-first need to run './autogen.sh'.

sources.
 
-Bubblewrap, installed as the bwrap binary, is a non-optional dependency
-on platforms where it is supported and thumbnailing will silently fail
-when it is not installed at runtime.
