iLikeThis plugin positioning

Hello,

I have installed iLikeThis plugin.

It is displaying under articles. I would like to position it under the articles’ titles (if it is possible at the right side). Also I would like to make it bigger.

I have read installation guide for this but have not figured out how to do it.

Can somebody tell me where exactly do I have to put the code, so it will display in each article as I described above?

Thank you.
