+## Toolversion Variable Passthrough
+
+Similar to the [Docker](./docker.md) task, the Goreleaser task will automatically pass any tool-version variables
+through to the Goreleaser Docker container.
+
+The set of arguments is parsed from the `.gitlab-ci-asdf-versions.yml` and `.gitlab-ci-other-versions.yml` files,
+if they exist.
+
+This can be customized through the `GL_VERSION_YML_FILES` variable.
