-# Divergent
+# Divergent identifies the most divergent biological sequences from a collection
 
-## Identifying the sequences that maximise Jensen-Shannon
+`divergent` provides tools for selecting a representative subset of sequences from a larger collection. It is an alignment-free method which scales linearly with the number of sequences.  It identifies the subset of divergent sequences that maximize the information theoretic measure Jensen-Shannon divergence. Divergent provides a command-line interface and plugins to the Cogent3 app system allowing users to embed code in their own scripts. The command-line tools can be run in parallel.
