I sure felt the same way when I was trying to get pat up and running. And in the past I have been a software developer.
We are talking Windows here, not Mac or Linux?
In any case the first step will be to open a command window or a terminal window, where you can enter text commands and see text responses.
Assuming Windows, pat will be installed in some directory. I'll assume that directory is c:\pat. You can open a command window by pressing the Windows key and the R key together. Key in "cmd". That should open a text mode window.
Then ensure you are in the directory the pat.exe file is stored. In this example,
cd\pat
Then key in
pat http
It should either do what you want, or return some error message. If it works further steps will set up a desktop icon that runs that command for you.
I suppose in the meantime I could install Pat on a Windows box and see how it goes for me. Then I would actually know what I am talking about.
