+          ## Verify checksums file signature
+
+          Install cosign on your system https://docs.sigstore.dev/system_config/installation/
+
+          The checksums file provided within the artifacts attached to this release is signed using [Cosign](https://docs.sigstore.dev/cosign/overview/) with GitHub OIDC. To validate the signature of this file, run the following commands:
+
+          \`\`\`shell
+          # Download the checksums file, certificate, and signature
+          curl -LO https://github.com/${{ github.repository_owner }}/${{ github.event.repository.name }}/releases/download/$RELEASE_TAG/checksums.txt
+          curl -LO https://github.com/${{ github.repository_owner }}/${{ github.event.repository.name }}/releases/download/$RELEASE_TAG/checksums.txt.pem
+          curl -LO https://github.com/${{ github.repository_owner }}/${{ github.event.repository.name }}/releases/download/$RELEASE_TAG/checksums.txt.sig
+
+          ### Verify the checksums file
+          cosign verify-blob checksums.txt \
+          --certificate checksums.txt.pem \
+          --signature checksums.txt.sig \

+          --certificate-oidc-issuer=https://token.actions.githubusercontent.com 
+          \`\`\`
+
+
+          ## Installation of secretgen-controller
+
+          secretgen-controller can be installed by using kapp 
+          \`\`\`shell
+          kapp deploy -a sg -f https://github.com/carvel-dev/secretgen-controller/releases/$RELEASE_TAG/download/release.yml
+          \`\`\`
+
+          or by using kubectl
+          \`\`\`shell
+          kubectl deploy -f https://github.com/carvel-dev/secretgen-controller/releases/$RELEASE_TAG/download/release.yml
+          \`\`\`
+
+          ### Container Images
+
+          secretgen-controller and secretgen-controller-package-bundle images are available in Github Container Registry.
+
+          ### OCI Image URLs

+          - $SGC_CONTROLLER_IMAGE
+          - $SGC_CONTROLLER_PACKAGE_BUNDLE_IMAGE
+
+          ### Verify container image signature
+
+          The container images are signed using [Cosign](https://docs.sigstore.dev/cosign/overview/) with GitHub OIDC. To validate the signature of OCI images, run the following commands:
+          \`\`\`shell
