XF 2.1 Insert code into footer?

[PrettyPixels]

I have some php code I need to insert into the footer of my site. Is there an easy way to do this without editing the templates?

You can't use PHP code in templates, lol.

/admin.php?template-modifications/add

That's why I'm asking. I'm coming from another system and thought someone could recommend the best way to include code on xenForo.
