I actually put the full license in a dedicated file and the "license" section of the README only contains a link to it. That's probably a bit redundant but it's an old habit from the time when GitHub did not include the license in the project page header.
That's usually something I put in the full documentation to keep the README more lightweight and free of unnecessary technical details.
