It all begins with the installation of PowerShell on your system. Installation of PowerShell is simple and straightforward. Since PowerShell is open source, its source code is available on the arguably largest platform for open source projects, GitHub. At the moment, Windows, Debian (and Ubuntu), RedHat Linux (and CentOS), Fedora and macOS are officially supported by the PowerShell project. Arch Linux and Kali Linux are supported by the community. Community support is also available for the AppImage edition of PowerShell that can be used on most of the modern-day Linux distributions.
An AppImage is a way of packaging applications to run on Linux distributions. Every application has its dependencies. On Linux, the package managers manage the installation of the dependencies while installing the packages. An AppImage package, on the other hand, packs all the necessary dependencies within itself. An AppImage can run in portable mode, or be installed on the system, based on user preference.
PowerShell is, as of writing of this chapter, experimentally available for Windows on ARM and Raspbian Stretch.
