 ### Create an input file
 
 First, create a file, e.g. `acc-url.csv` with identifiers, sketch names, and other required info.

 > Six columns must be present:
 > - `accession` - an accession or unique identifier. Ideally no spaces.
 > - `name` - full name for the sketch.
 > - `moltype` - is the file 'dna' or 'protein'?
-> - `md5sum` - expected md5sum (optional, will be checked after download if provided)
+> - `md5sum` - expected md5sum(s). Optional, will be checked after download if provided.
 > - `download_filename` - filename for FASTA download. Required if `--keep-fastas`, but useful for signatures, too (saved in sig data).
-> - `url` - direct link for the file
+> - `url` - direct link(s) for the file(s)
+> - `range` - if desired, include base pair range(s), e.g 500-10000. This range will be selected from the record(s) and sketched (and/or saved to the download_filename). If there are multiple records in a FASTA file, the range will be applied to each record.
+
+#### Note: Merging Files into the same signature
+As of v0.5.0, `urlsketch` allows specification of multiple URLs to be downloaded and sketched into a single signature. If providing multiple URLs for a single accession/name, you must either provide no `md5sum` or `range`, or the number of entries in these columns must match the number of URLs. In each case, separate the entries with ';' -- e.g. "abc;def" for two md5sums.
