- You need an existing installation of official Blender from
   http://www.blender3d.org
   
 - Place this binary (iblender2) into the same directory as
   the official binary
   
 - instinctive-blender uses its own UserPref file (~/.IB.blend),
   so you can safely hit CTRL-U without disturbing the official
   Blender's preferences
   
 - instinctive-blender will NOT read your existing official Blender
   preferences (~/.B.blend)!
