This is testing task which was given to me by "site direct" company. As I have decided at the beginning to accomplish this using good practices, I don't want this to be thrown to recycle bin.
Probably this code may be useful for someone (or even for me) later.
Create (virtual) host in you web-server. Create new MySQL database. Fill DB access details in the file </etc/config.php> (corresponding section should be obvious).
Open the host homepage in browser. In 1st run it will install automatially with sample data. (For security reasons remove predefined users from DB table). Predefined users are (name / password): user / user admin / admin
