If you would like to use a stable, predictable, manageable and reproducible distribution in your AppVMs, you can install the CentOS template, provided by Qubes in ready to use binary package.
To switch, reinstall and uninstall a CentOS TemplateVM that is already installed in your system, see [How to switch, reinstall and uninstall](/doc/templates/#how-to-install-uninstall-reinstall-and-switch).
#### After Installing
After a fresh install, we recommend to [Update the TemplateVM](/doc/software-update-vm/).
