Install
The installer, Install Quasar.sh, is a self-extracting script file. It must have its executable bit set to be able to run it. It must be run as the root user. Here is how to launch the installer.
Read instructions below, or watch this demo video.
// todo embed anything block with the video
Open a Terminal.
Go to the location where you downloaded Install Quasar.sh.
Optionally list the files in the directory.
Set the executable bit on Install Quasar.sh. Note that the filename is case sensitive. Terminal allows you to press the TAB key to complete the typing of a filename for you. For example, type chmod +x ./I and then press TAB and your terminal prompt text will change to chmod +x ./Install\ Quasar.sh. The "\ " is how you type a space in a filename.
Optionally list the files in the directory.
Run the installer. Again, type ./I and then TAB to finish the typing for you.
It will ask you for your root (sudo) password.
After the installer user interface closes, and the terminal prompt is ready again, delete the installer because it is no longer needed.
