add a logo

Hello !

In your Birdfield theme:

I want to add a logo over my header image and her place is after the nav bar to left side. Like on the screenshot. Currently my logo is on the same jpg that my background image of header. My logo background is already transparent.

I have already a child theme, it just for understanding which kind of code I’ve got to write, on php file and css.

Thank you.
