GoDocs has been built to be as configurable as possible.
Change the logo
In config.toml you will find a logo variable. you can change your logo there.
logo = "images/logo.png"
The size of the logo will adapt automatically
Change the favicon
If your favicon is a png, just drop off your image in your local static/images/ folder and name it favicon.png
If you need to change this default behavior, create a new file in layouts/partials/ named head.html. Then write something like this:
<link rel="shortcut icon" href="/images/favicon.png" type="image/x-icon" />
