+### Build an image with Software Bill of Materials
+
+Build an image with a Software Bill of Materials (SBOM) using the `sbom` and `sbom-dir` inputs. The `sbom` input will generate an SBOM for the image, and the `sbom-dir` input will output the SBOM to the specified directory. You can then use the `actions/upload-artifact` action to upload the SBOM directory as a build artifact.
