How to install Projeqtor in Linux Ubuntu with terminal

1) first you have to install PHP and MySql.
You'll find many totorials for this on the web.

2) then you need to get projeqtor zip file.
Best is to download it from repository (look at download page) and copy it via scp for instance
You can also retreive it directly :
wget www.projeqtor.org/version/projeqtor_v5.1.3.zip
Unzip this in the PHP web directory (/var/www/ or /var/www/html)
Then access projector with your browser to start configuration.

I'm afraid you'll have much difficulties to install projector if you don't have basis knowledge of linux.

something like :should install php and apache and mysql if it's not installed.
But you'll need more for php extensions and mysql configuration.
