+## Portions Copyright Broad Institute, 2018
+##
+## This WDL pipeline implements QC in human whole-genome or exome/targeted sequencing data.
+##
+## Requirements/expectations
+## - Human paired-end sequencing data in aligned BAM or CRAM format
+## - Input BAM/CRAM files must additionally comply with the following requirements:
+## - - files must pass validation by ValidateSamFile
+## - - reads are provided in query-sorted order
+## - - all reads must have an RG tag
+## - Reference genome must be Hg38 with ALT contigs
+##
+## Runtime parameters are optimized for Broad's Google Cloud Platform implementation.
+## For program versions, see docker containers.
