how do i add code to template page?

Hi

im new to wordpress and i just installed your Easy Testimonials (http://wordpress.org/plugins/easy-testimonials/) i can get it to work on post or pages by including [testimonials_cycle show_title=”1″ timer=”5000″] code into the WYSIWYG

But how do i get it to work on a template page? so that its at the bottom of all pages?

I tried adding this code to the PHP file [testimonials_cycle show_title=”1″ timer=”5000″]
but it didnt work.

Sorry if this is a newbie question.

cheers
Jim
