+## Upload S3 assets
+
+A number of scripts create files in the `tmp/s3_assets` folder, which then can

+
+```yaml
+- name: Setup
+  uses: mongodb-labs/drivers-github-tools/setup@v2

+- name: Upload S3 assets
+  uses: mongodb-labs/drivers-github-tools/upload-s3-assets@v2
+  with:
+    version: <release version>
+    product_name: <product_name>
+```
+
+Optionally, you can specify which files to upload using the `filenames` input.
+By default, all files in the S3 directory are uploaded.
