 In order to use the system for your calculations, you need basic proficiency in Linux environment. To gain the proficiency, we recommend you reading the [ introduction to Linux](http://www.tldp.org/LDP/intro-linux/html/)![external](img/external.png) operating system environment and installing a Linux distribution on your personal computer. A good choice might be the [ Fedora](http://fedoraproject.org/)![external](img/external.png) distribution, as it is similar to systems on the clusters at IT4Innovations. It's easy to install and use. In fact, any distribution would do.
