Neofetch is a CLI system information tool written in BASH. Neofetch displays information about your system next to an image, your OS logo, or any ascii file of your choice. The main purpose of neofetch is to be used in screenshots to show other users what OS/Distro you're running, what Theme/Icons you're using and etc. To see any optional dependencies that you might need, you can view it in https://github.com/dylanaraps/neofetch/wiki/Dependencies
