+If you are a Prowler Saas customer and you want to use your data from your S3 bucket, you can run:
+
+```sh
+aws s3 cp s3://<your-bucket>/output/csv ./output --recursive

+to load the dashboard with the new files.
+
+## Output Path
+
+Prowler will use the outputs from the folder `/output` (for common prowler outputs) and `/output/compliance` (for prowler compliance outputs) to generate the dashboard.
