# Contributing
Patches are welcome. How the project works, what proof a change needs, and the
writing rules are on the documentation site:
<https://docs.forgefirm.org/developers/contributing/>.
## Sign your work
Every commit carries a `Signed-off-by` line:
Signed-off-by: Your Name <your.email@example.com>
`git commit -s` adds it, using your `user.name` and `user.email`. Use your real
name; an anonymous or pseudonymous sign-off certifies nothing.
The line certifies the Developer Certificate of Origin, version 1.1, below. It
is the same statement the Linux kernel and grblHAL use. It is not a copyright
assignment: you keep the copyright in what you write, and your contribution
comes in under the license of the repository you are contributing to.
You do not add a copyright line for a patch. A change to an existing file
leaves its header alone. If you write a whole new file, put your own name in
its copyright line, or leave the line out; either way the file carries an
`SPDX-License-Identifier` for the repository's license.

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

maintained indefinitely and may be redistributed consistent with
this project or the open source license(s) involved.
