1. rename files
copy_of_index.php to index.php
copy_of_new.php to new.php

2. create subfolders
/images
/db

3. In /db subfolder create a text file name
poll.ini
and place the digit 0 in it

4. change $root to whatever root folder also in new.php

5. MUST create at least first poll or else an error will occure (new.php)
