-### API rate limit

-To avoid hitting the `API rate limit exceeded` error, supply a GitHub token via the `github-token`
-input.
+This action uses the GitHub API to fetch the `uv` release artifacts. To avoid hitting the GitHub API
+rate limit too quickly, an authentication token can be provided via the `github-token` input. By
+default, the `GITHUB_TOKEN` secret is used, which is automatically provided by GitHub Actions.
+
+If the default
+[permissions for the GitHub token](https://docs.github.com/en/actions/security-for-github-actions/security-guides/automatic-token-authentication#permissions-for-the-github_token)
+are not sufficient, you can provide a custom GitHub token with the necessary permissions.
