 ## Fast download BLAST databases from NCBI
 
 Database files (volumes) are downloaded in parallel: number of threads to use
-is determined automatically. MD5 checksum is verified and the database files
-extracted upon download. Database volumes are not downloaded in a particular
-order. Downloads are incremental, that is it will only download new data,
-provided the `.tar.gz` files have not been deleted.

+or re-downloaded if corrupt. Aborted downloads are safely resumed.
