[Trisquel-users] Need help with program installation

[aninymis]

I downloaded Peerguardian 2.2.2 for GNU/Linux from Sourceforge and extracted  
the archive (tar.gz format). I see a lot of files in the program folder, but  
I don't know what to do next. I also have the same problem with OpenVPN and  
other programs. Am I supposed to type command lines? Which file am I supposed  
to open?

I have been using Windows for a long time, so I have grown accustomed to  
running .exe files and using GUI installation wizards. I am not familiar with  
program installation in GNU/Linux operating systems. I know how to download  
software from the repositories, but I don't know much about 'manual'  
installation or Terminal commands. Can anybody please help me? Where can I  
find manuals or resources for novice users?
