Quickstart: After installing Bluetile (use 'cabal install') just open a
terminal under your current window manager/desktop environment
(preferably GNOME) and enter 'bluetile' or '/path/to/bluetile' if it's not
in your PATH. Bluetile will replace the currently running window manager
(if the window manager supports this) and start up.

See the man page of Bluetile for further information - including how to
set up Bluetile as your permanent window manager.
