# Contributing code to libolm
|
|
|
|
To contribute code to this library, the preferred way is to clone the git
|
|
repository, create a git patch series (for example via ``git
|
|
format-patch --stdout origin/master``), and send this by email to
|
|
``olm@matrix.org``.
|
|
|
|
Naturally, you must be willing to license your contributions under the same
|
|
license as the project itself - in this case, Apache Software License v2 (see
|
|
[LICENSE](LICENSE)).
|
|
|
|
## Sign off
|
|
|
|
In order to have a concrete record that your contribution is intentional and
|
|
you agree to license it under the same terms as the project's license, we've
|
|
adopted the same lightweight approach that the
|
|
[Linux Kernel](https://www.kernel.org/doc/html/latest/process/submitting-patches.html#sign-your-work-the-developer-s-certificate-of-origin),
|
|
[Docker](https://github.com/docker/docker/blob/master/CONTRIBUTING.md),
|
|
and many other projects use: the DCO ([Developer Certificate of Origin](http://developercertificate.org/)).
|
|
This is a simple declaration that you wrote the contribution or otherwise have
|
|
the right to contribute it to Matrix::
|
|
|
|
Developer Certificate of Origin
|
|
Version 1.1
|
|
|

Copyright (C) 2004, 2006 The Linux Foundation and its contributors.

Everyone is permitted to copy and distribute verbatim copies of this
|
|
license document, but changing it is not allowed.

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.
|
|
|
|
If you agree to this for your contribution, then all that's needed is to
|
|
include the line in your commits or covering email::
|
|
|
|
Signed-off-by: Your Name <your@email.example.org>
|
|
|
|
...using your real name; unfortunately pseudonyms and anonymous contributions
|
|
can't be accepted. Git makes this trivial - just use the -s flag when you do
|
|
``git commit``, having first set ``user.name`` and ``user.email`` git configs
|
|
(which you should have done anyway :)
