+## Dependency check scanner

+This project uses [sbt-dependency-check](https://github.com/albuch/sbt-dependency-check) in order to scan the
+projects dependencies against [OWASP](https://owasp.org/) to create a @ref:[dependency-check-report](dependency-check-report.md)

+If you want to suppress the checking of some dependencies then there is a [supression](github:dependency-check/suppression.xml)
+file. The format of this file is documented [here](https://jeremylong.github.io/DependencyCheck/general/suppression.html).
