+
+- Align two or more sequences using blastp, with the e-value threshold of 1e-9, pairwise output format, output to screen:
+
+`blastp -query {{query.fa}} -subject {{subject.fa}} -evalue {{1e-9}}`
+
+- Align two or more sequences using blastp-fast:
+
+`blastp -task blastp-fast -query {{query.fa}} -subject {{subject.fa}}`
+
+- Align two or more sequences, custom tabular output format, output to file:
+
+`blastp -query {{query.fa}} -subject {{subject.fa}} -outfmt '{{6 qseqid qlen qstart qend sseqid slen sstart send bitscore evalue pident}}' -out {{output.tsv}}`
+
+- Search protein databases using a protein query, 16 threads to use in the BLAST search, with a maximum number of 10 aligned sequences to keep:
+
+`blastp -query {{query.fa}} -db {{blast_database_name}} -num_threads {{16}} -max_target_seqs {{10}}`
+
+- Search the remote non-redundant protein database using a protein query:
+
+`blastp -query {{query.fa}} -db {{nr}} -remote`
+
+- Display help (use `-help` for detailed help):
+
+`blastp -h`
