+##  Sign your work - the Developer's Certificate of Origin
+The sign-off is a simple line at the end of the explanation for the patch, which certifies that you wrote it or otherwise have the right to pass it on as an open-source patch.
+The rules are pretty simple: if you can certify the below (from developercertificate.org):
+
+> Developer's Certificate of Origin 1.1
+>
+> By making a contribution to this project, I certify that:
+>
+> (a) The contribution was created in whole or in part by me and I
+>     have the right to submit it under the open source license
+>     indicated in the file; or
+>
+> (b) The contribution is based upon previous work that, to the best
+>     of my knowledge, is covered under an appropriate open source
+>     license and I have the right under that license to submit that
+>     work with modifications, whether created in whole or in part
+>     by me, under the same open source license (unless I am
+>     permitted to submit under a different license), as indicated
+>     in the file; or
+>
+> (c) The contribution was provided directly to me by some other
+>     person who certified (a), (b) or (c) and I have not modified
+>     it.
+>
+> (d) I understand and agree that this project and the contribution
+>     are public and that a record of the contribution (including all
+>     personal information I submit with it, including my sign-off) is
+>     maintained indefinitely and may be redistributed consistent with
+>     this project or the open source license(s) involved.
+
+#### DCO Sign-Off Methods
+
+The DCO requires a sign-off message in the following format appear on each commit in the pull request:
+
+> Signed-off-by: Random J Developer <random@developer.example.org>
+
+using your real name (sorry, no pseudonyms or anonymous contributions.)
+
+The DCO text can either be manually added to your commit body, or you can add either **-s** or **--signoff** to your usual git commit commands.
+If you forget to add the sign-off you can also amend a previous commit with the sign-off by running **git commit --amend -s**.
+If you've pushed your changes to GitHub already you'll need to force push your branch after this with **git push -f**.
+
+
+#### Alternative Sign-Off Methods in rare cases
+
+If it is really no option for you to disclose your real name and email address, there might be a chance that you can get your contribution accepted.
+In this case please contact the maintainers directly and verify the adherence to the DCO of the contribution manually.
+This might include quite some legal overhead for both parties.
