+      Snakemake is a workflow management system that aims to reduce the complexity of
+      creating workflows by providing a fast and comfortable execution environment,
+      together with a clean and readable specification language in Python style. Snakemake
+      workflows are essentially Python scripts extended by declarative code to define
+      rules. Rules describe how to create output files from input files.
