+This project is using Trivy as a vulnerability scanner to replace the role of `tfsec` with some extra benefits:
+1. Access to more languages and features in the same tool.
+2. Access to more integrations with tools and services through the rich ecosystem around Trivy.

+## Trivy Local Scan
+```bash
+# Project root directory
+trivy config .
