 ## How to install and start MISP modules on RHEL-based distributions ?
 As of this writing, the official RHEL repositories only contain Ruby 2.0.0 and Ruby 2.1 or higher is required. As such, this guide installs Ruby 2.2 from the [SCL](https://access.redhat.com/documentation/en-us/red_hat_software_collections/3/html/3.2_release_notes/chap-installation#sect-Installation-Subscribe) repository.
