+### Using Trivy to generate SBOM
+It's possible for Trivy to generate an SBOM of your dependencies and submit them to a consumer like GitHub Dependency Snapshot.
+
+The sending of SBOM to GitHub feature is only available if you currently have [GitHub Dependency Snapshot](https://docs.github.com/en/code-security/supply-chain-security/understanding-your-software-supply-chain/using-the-dependency-submission-api) available to you in your repo. 
+
+In order to send results to the GitHub Dependency Snapshot, you will need to create a [GitHub PAT](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token)
+```yaml

 ### Using Trivy to scan your private registry
 It's also possible to scan your private registry with Trivy's built-in image scan. All you have to do is set ENV vars.
