# Manage templates (VDI)

Templates are used to automate the creation and deployment of hosts in Parallels RAS. A template is based on an existing virtual machine created with one of the hypervisors supported by Parallels RAS. Once a template is ready, it can be used to create clones (hosts) that will inherit all properties of the template. The resulting hosts can then be used to host published resources.

Read the following topics to learn how to create and use a template.
