include path gems hostgator

i buyed a web hosting. i installed some gems.
in the hostgator's instructions there is write:

Using Your Ruby Gem(s)

You will need to add /home/nerto/ruby/gems to the include path.
You can do this by adding the following code to your script:

$:.push("/home/nerto/ruby/gems")

but i don't understand where i must to put it

Can you help me?
thanks
