# Contributions Guidelines
## Code formatting
Try to follow the existing formatting.
If there is no existing formatting, you may use `clang-format` with our included `.clang-format` configuration.
In general, in order of importance:
- Make sure your IDE is not messing up line endings or whitespace and avoid using linters.
- Prefer readability over dogma.
- Keep to the existing formatting.
- Indent with 4 space unless it's in a submodule.
- Keep lists (of arguments, parameters, initializers...) as lists, not paragraphs. It should either read from top to bottom, or left to right. Not both.
## Signing your work
In an effort to ensure that the code you contribute is actually compatible with the licenses in this codebase, we require you to sign-off all your contributions.
This can be done by appending `-s` to your `git commit` call, or by manually appending the following text to your commit message:
```
<commit message>
Signed-off-by: Author name <Author email>
```
By signing off your work, you agree to the terms below:
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.
These terms will be enforced once you create a pull request, and you will be informed automatically if any of your commits aren't signed-off by you.
As a bonus, you can also [cryptographically sign your commits][gh-signing-commits] and enable [vigilant mode][gh-vigilant-mode] on GitHub.
