Need help adding a logo instead of text header to a wordpress theme template

I found a great wordpress theme that I am customizing for my needs. For the title of the site it has text instead of a logo. I have a logo designed for the blog and would like to use it instead of just text. I need help with css to add the logo.

Here is what it looks like now:
