[HowTo] Install Flexget (automate your whole downloading process)

Huh?
Lots of posts link to external scripts, for example @zatarra OP in his Spotify Connect HowTo links to a similar installation .sh script, it directly links to it:

You wanted me to split the HowTo’s up, so I updated the HowTo’s the option to use the script while maintaining the manual process. If you look at the script, it is simply a total list of all How To commands and an IF tags.

Please help me understand why my post is not allowed to contain a .sh script? I am only trying to make things easier especially for noobs, so that these tools become more widely used and less questions are being asked in topics. Also, it speeds up a fresh installation massively if you don’t have to type in the commands one by one and wait for each one to finish. It is a lot easier to simply change a 1 into a 0 or vice versa to install something.
