???+ note "Which Startup Scripts types are supported?"

    Vultr supports several types of Startup Scripts:

    * Linux systems use cloud-init user-data. See [Deploy a Vultr Server with     
    * Cloud-Init User-Data](https://docs.vultr.com/how-to-deploy-a-vultr-server-with-cloudinit-userdata) for more details.
    * Fedora CoreOS uses Ignition. See the [Ignition user guide](https://docs.vultr.com/ignition) and the [Fedora CoreOS documentation](https://docs.fedoraproject.org/en-US/fedora-coreos/producing-ign/) for details.
    * Windows and *BSD systems use boot scripts.

    Startup scripts require a two-step process. First, add a script to your account. Then, assign that script to an instance under **Server Settings** when deploying the instance.
