 A GitHub Action that reads Cobertura format code coverage files from your test suite and outputs a text or markdown summary. This summary can be posted as a Pull Request comment or included in Release Notes by other actions to give you an immediate insight into the health of your code without using a third-party site.
 
-Code Coverage Summary is designed for use with [Coverlet](https://github.com/coverlet-coverage/coverlet) and [gcovr](https://github.com/gcovr/gcovr) but it should work with any test framework that outputs coverage in Cobertura format.

See the [FAQ](https://github.com/irongut/CodeCoverageSummary/wiki/Frequently-Asked-Questions#which-testing-tools-does-ccs-work-with) for more details. If it doesn't work with your tooling please [open an issue][new-issue] to discuss the problem.
+
+Code Coverage Summary is compatible with [StepSecurity Secure Workflows](https://github.com/step-security/secure-workflows) and uses a Docker image that is cryptographically signed using [Sigstore](https://www.sigstore.dev/). For instructions how to verify the Docker image please see the [Wiki](https://github.com/irongut/CodeCoverageSummary/wiki/Verify-the-Docker-Image).
 
 As a Docker based action Code Coverage Summary requires a Linux runner, see [Types of Action](https://docs.github.com/en/actions/creating-actions/about-custom-actions#types-of-actions). If you need to build with a Windows or MacOS runner a workaround would be to upload the coverage file as an artifact and use a separate job with a Linux runner to generate the summary.
