This can be done in the form of a cover letter for the patch series while sending changes as patches via e-mail; or it can be comments in the pull request while using collocated contributor repositories model; or it can be the description in an e-mail with a pull request, which already includes the URL and the branch in your public repository with changes (generated with git request-pull).
