 To export the data as HTML, run monocov like this:
 	monocov --export-html=<DEST DIR> <DATA FILE NAME>
 
+You can use this application to track your code coverage as part of your build
+process. To specify a minimum methode coverage of 50% and a minimum class coverage
+of 80%:
+	monocov --minClassCoverage=0.5 minMethodeCoverage=0.8 <DATA FILE NAME>
