We have created a debian repository to make it easier to use our tutorials. This repository allows you to install all required software and example data included in tutorials on your computer. Using this repository will require that you have administrator access to a 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, you can install a Virtual Machine program (such as [https://www.virtualbox.org/ VirtualBox]) on your computer, and then load our pre-configured virtual machine image (VM Image) into the Virtual Machine.You can refer to these online videos [[VirtualBox Installation|here]] to install VirtualBox on your computer.
