Changes

We have created a debian repository to make it easier to use our tutorials. Using this repository will require that you have administrator access to the computer with Linux System. If you don't have this level of access or your computer running non-Linux systems (Windows or OS), you have two options. First, you could install the repository on a remote cloud serve, such as [https://www.vultr.com/ VULTR]. Second, we also provide a pre-configured virtual machine image that will allow you to install software , but you have to install a virtual machine program (such as rootVirtualBox) on your computer.
