-# `diverse_seq` identifies the most diverse biological sequences from a collection
+# `diverse_seq` provides alignment-free algorithms to facilitate phylogenetic workflows
 
-`diverse_seq` 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 sequences that maximize diversity as measured using Jensen-Shannon divergence. `diverse_seq` provides a command-line tool (`dvs`) and plugins to the Cogent3 app system (prefixed by `dvs_`) allowing users to embed code in their own scripts. The command-line tools can be run in parallel.
+`diverse-seq` implements computationally efficient alignment-free algorithms that enable efficient prototyping for phylogenetic workflows. It can accelerate parameter selection searches for sequence alignment and phylogeny estimation by identifying a subset of sequences that are representative of the diversity in a collection. We show that selecting representative sequences with an entropy measure of *k*-mer frequencies correspond well to sampling via conventional genetic distances. The computational performance is linear with respect to the number of sequences and can be run in parallel. Applied to a collection of 10.5k whole microbial genomes on a laptop took ~8 minutes to prepare the data and 4 minutes to select 100 representatives. `diverse-seq` can further boost the performance of phylogenetic estimation by providing a seed phylogeny that can be further refined by a more sophisticated algorithm. For ~1k whole microbial genomes on a laptop, it takes ~1.8 minutes to estimate a bifurcating tree from mash distances.
