|  | Add a `Signed-off-by` trailer by the committer at the end of the commit | 
|  | log message.  The meaning of a signoff depends on the project | 
|  | to which you're committing.  For example, it may certify that | 
|  | the committer has the rights to submit the work under the | 
|  | project's license or agrees to some contributor representation, | 
|  | such as a Developer Certificate of Origin. | 
|  | (See https://developercertificate.org for the one used by the | 
|  | Linux kernel and Git projects.)  Consult the documentation or | 
|  | leadership of the project to which you're contributing to | 
|  | understand how the signoffs are used in that project. | 
|  | + | 
|  | The `--no-signoff` option can be used to countermand an earlier `--signoff` | 
|  | option on the command line. |
