+# `@thebrowsercompany/gha-download-tar-artifact`
+
+Download and untar [Action Artifacts](https://docs.github.com/en/actions/using-workflows/storing-workflow-data-as-artifacts) from your Workflow Runs.

This action uses [@actions/download-artifact](https://github.com/actions/download-artifact) to download the tar file and untar it, preserving permissions on non-Windows platforms.
+
+See also [gha-upload-tar-artifact](https://github.com/thebrowsercompany/gha-upload-tar-artifact). For further documentation, refer to the [@actions/download-artifact](https://github.com/actions/download-artifact) documentation.
