PIWIK Code

hello, I would like to insert a tracking code for PIWIK Analytics in the footer. where and how can I do this? can I insert the code at google analytics code?
Thanks for your help.

I thought PIWIK wants the javascript inserted just inside the body tag?
Not sure in Blocs how close you could get it to the opening body tag. The Google analytics goes in the head section.
