How to place my javascript where I want it on the website?

Hi

I'm new to Umbraco, so I wonder if anyone could help me with this.

I want to insert a LinkedIn follow-button on my website, but I shows in the left corner of my website. How do I place it another place. I would like to place it in the footer of my page, in a textbox? Do I have to define an ID to the javascript or what?

Hope you can help, thanks.

Regards Mathias
