Discussed in #70

Hi @fatihtokus . Many thanks for this brilliant Trivy module! in passing, I ran an OpenSSF (https://openssf.org) scorecard check on the repo as a method to encourage my colleagues to use your module. I don't know if you know of the scorecard but here is the current report of the repository. A high-scoring ossf scorecard badge could help you further garner more widespread usage.

$ scorecard --repo https://github.com/fatihtokus/scan2html
