+## Versioning
+
+This GitHub Action follows the principles of [Semantic Versioning](https://semver.org) for versioning releases.
+
+In addition to the standard versioning scheme, this action also uses the `v[major.minor.patch]-sec` convention for versions that implement hardening security strategies as described in the [GitHub Actions security hardening guide](https://docs.github.com/en/actions/security-guides/security-hardening-for-github-actions#using-third-party-actions).
+
+The format of the version string is as follows:
+
+major: is a major release number that indicates significant changes or new features that may not be backward compatible.
+minor: is a minor release number that indicates minor changes or new features that are backward compatible.
+patch : is a patch release number that indicates bug fixes or other small changes that are backward compatible.
+
+`-sec` is a suffix that indicates a security-hardened version that implements additional security measures.
+
+For example, `v1.2.3-sec` would indicate a security-hardened version of the action with major version 1, minor version 2, and patch version 3.
+
+Using this versioning convention helps ensure that users can easily identify and choose security-hardened versions of this action when integrating it into their workflows.
