+description: |
+  Haplocheck detects contamination patterns in mtDNA AND WGS sequencing studies by analyzing
+  the mitochondrial DNA. Haplocheck also works as a proxy tool for nDNA studies and provides
+  users a graphical report to investigate the contamination further. Internally, it uses the
+  Haplogrep tool, that supports rCRS and RSRS mitochondrial versions.
