+     "This package implements an R interface to the Leiden algorithm, an
+iterative community detection algorithm on networks.  The algorithm is
+designed to converge to a partition in which all subsets of all communities
+are locally optimally assigned, yielding communities guaranteed to be
+connected.  The implementation proves to be fast, scales well, and can be run
+on graphs of millions of nodes (as long as they can fit in memory).")
