Here's how to Install AppImage on Linux
AppImage is a universal software package format that can be installed on any Linux Distro. It doesn't use the traditional way of installation but rather, it is a compressed image of all the dependencies and libraries a software need to run.
With this, it doesn't need root permission to install or run the software.
Here's how to install and run App Images on Linux:
chmod u+x <appimage_file>
