 ### Using Trivy to scan your Git repo
 It's also possible to scan your git repos with Trivy's built-in repo scan. This can be handy if you want to run Trivy as a build time check on each PR that gets opened in your repo. This helps you identify potential vulnerablites that might get introduced with each PR.
