 Note that the order of sequences in the original FASTA file is preserved.
 Also, if any sequences share an identifier, duplicates are not removed.
 
+**Example Usage**
+
+Given a FASTA file of proteins you might run a signal peptide search (e.g.
+via the SignalP wrapper for Galaxy), then filtered these tabular results to
+select just those with a signal peptide. You could then use this tool to get
+a FASTA file of only the proteins with predicted signal peptides.
