# Zonemaster users guide The purpose of the Zonemaster project is to develop a DNS validation software. There are three ways one can use the Zonemaster software: * Using the Web user Interface: In this case, there is no installation of the Zonemaster software needed. A user types the URL [https://zonemaster.net][zonemaster.net], provides as input a domain name, and then can view the results. * From the Command Line Interface (CLI): In this case, the user has to install two components of the Zonemaster software, i.e. the [Zonemaster-Engine] and the [Zonemaster-CLI]. * There are cases, wherein an organisation or a user, that wants to have the results of their DNS validation stored and can be viewed later. In that case, in addition to the Zonemaster-Engine and Zonemaster-CLI, the user has to install the [Zonemaster-Backend] and the [Zonemaster-GUI].
