The most important command you might ever use in pack is called 'flash'.
The Flash command flashes(installs) the payload of a .pack installer onto
the users system. Heres an example below
as you can see the syntax is not that hard to use. All you need to do is run
pack flash then the path to the installer file. Note installer files DO NOT need
to have the .pack extension. As pack installers are just gzipped tar archives.
