+      The GATK is the industry standard for identifying SNPs and indels in germline
+      DNA and RNAseq data. Its scope is now expanding to include somatic short variant
+      calling, and to tackle copy number (CNV) and structural variation (SV). In
+      addition to the variant callers themselves, the GATK also includes many
+      utilities to perform related tasks such as processing and quality control of
+      high-throughput sequencing data, and bundles the popular Picard toolkit.
+
+      These tools were primarily designed to process exomes and whole genomes
+      generated with Illumina sequencing technology, but they can be adapted to handle
+      a variety of other technologies and experimental designs. And although it was
+      originally developed for human genetics, the GATK has since evolved to handle
+      genome data from any organism, with any level of ploidy.
