Templates of popular operating systems like Debian, CentOS can be used. Scripts can help with detailed OS settings and installation of third party software. Also, there are ready templates and scripts available from official ISPsystem repository.

Shell-scripts enable to install additional applications automatically on a server after OS deployment or at any other time.

Let’s consider the example. A user organizes hackathons for web apps development. By using scripts, the user can prepare 20 VMs easily within a few minutes. Recipes will automatically install Django on machines, so that the participants would receive ready environment for Python development. Such scripts can be for other apps e.g. BigBlueButton, Redmine, OpenVPN, or TeamSpeak.

While OS templates are normally created by providers, recipes can be easily used by end users. All they need to do is enter their code in the field of the corresponding menu in VMmanager. Scripts can be created in any language if the OS supports the required interpreter.
