Vega Installation
Download the archive corresponding to your architecture Linux GTK 32-bit Intel | Linux GTK 64-bit Intel
Unzip it in your home directory, or wherever appropriate.
Change into your home directory and run ./Vega. 

Using Vega:
When you start Vega for the first time, you will be in the scanner perspective. Vega has two perspectives: The scanner, and the proxy. The Vega scanner is an automated security testing tool that crawls a website, analyzing page content to find links and form parameters. Vega finds injection points, referred to as path state nodes, and runs modules written in Javascript to analyze them. Vega also runs Javascript modules on all responses sent back from the server during the scan.
Open up the Vega UI and type the site address on which you need to perform the security scanning.
