Fork me on GitHub


tl;dr get me to fix

Welcome to, you are probably here because you forgot to sign-off at least one commit.

What does that mean?

By signing-off your commits you make the following declaration.
Simply put, by signing off your commits you are telling the maintainers that to the best of your knowledge the patch you, or a third party, has created is able to be distributed under a compatible open-source license and it does not infringe on copyrighted material.


If it's your last one, you are in luck, just do
git commit --amend -s --no-edit
and do a force push. If you have more than one commit that's not signed-off
git filter-branch --msg-filter "cat - && echo && echo 'Signed-off-by: Your Name <[email protected]>'" HEAD

and do a force push.
