WordPress › Support » MeeBoo in Sidebar

Hi.
I'm a newbie to WordPress so please bear with me, the question is probably stupid.

I want to implement MeeBoo to my sidebar, I got the line of php code to put in, but I dont know which page to put it into?
I'm not too familiar with coding, I've worked a fair bit with coppermine photo galleries earlier but that doesn't help here, obviously:)

Hope someone can direct me to which page I have to edit to implement MeeBoo into my sidebar.
