-Prowler for OpenStack allows you to audit your OpenStack cloud infrastructure for security misconfigurations, including compute instances, networking, identity and access management, storage, and more.
+Prowler supports OpenStack both from the CLI and from Prowler Cloud. This guide walks you through the requirements, how to connect the provider in the UI, and how to run scans from the command line.

+3. Enter the "Cloud Name" — this is the key that identifies the cloud entry inside the `clouds.yaml` file (e.g., `mycloud`).
