 distribution's repositories, which can greatly reduce your update times
 depending on your internet connection.
 
+Most users however don't need a full copy of a distro's package repository, so
+Rieter also provides a "smart mirror" mode. In this mode, a Rieter instance
+only syncs packages that have been requested before, e.g. from a previous
+system update. This way, your updates will still be a lot faster as the
+required packages are cached, but packages you don't use don't get stored,
+saving you a lot of storage space.

 ### Build system
 
 The second goal is to create an easy-to-use build system for Pacman packages.
