-        Retrieve SRR accessions by BioSample or BioProject.
+        Retrieve SRR accessions and metadata from a BioProject.
+
+        If you have metadata for your own samples (that aren't from the BioProject) you can provide a TSV table with it and they'll be folded together. (It's a union, not a join.) Put sample ID's under the header 'sample'.
