-The 'tax prepare' command reads in one or more taxonomy databases
-and saves them into a new database. It can be used to combine databases
-in the desired order, as well as output different database formats.
+`sourmash tax grep` searches taxonomies for matching strings,
+optionally restricting the string search to a specific taxonomic rank.
+It creates new files containing matching taxonomic entries; these new
+files can serve as taxonomies and can also be used as picklists.
