+
+This action makes HTTP requests to the GitHub API to determine the URL of
+the assets to download. By default, these requests are made anonymously,
+which means that they are subject to harsher rate limits. If you encounter
+rate limiting issues, you can set the `GITHUB_TOKEN` environment variable to
+authenticate the requests.
