+It is kept up to date with upstream, adding a few additional features such
+as gaps between windows.
+
+i3 is a tiling X11 window manager that dynamically manages
+tiled, stacked, and tabbed window layouts.
+
+i3 primarily targets advanced users.  Windows are managed manually and 
organised
+inside containers, which can be split vertically or horizontally, and 
optionally
+resized.
+
 i3 uses a plain-text configuration file, and can be extended and controlled 
from
 many programming languages.")
