+You can specify an S3 bucket to cache dependencies in order to speed up runs, in which case you will need to configure AWS credentials like so:
+
+```yaml
+jobs:
+  build:
+    steps:
+      - uses: aws-actions/configure-aws-credentials@v4
+        with:
+          aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
+          aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}

+          s3-bucket-name: <bucket-name>
+          s3-bucket-region: us-east-1
+```

 If you are using this action for protected branches, replace `GITHUB_TOKEN`
 with [Personal Access Token](https://help.github.com/en/github/authenticating-to-github/creating-a-personal-access-token-for-the-command-line).
