# Licensing
|
|
|
|
Zulip is distributed under the [Apache 2.0
|
|
license](https://github.com/zulip/zulip/blob/main/LICENSE). This means that all
|
|
contributions to Zulip — code, images, sounds, etc. — must be compatible with
|
|
this license.
|
|
|
|
## Contributing your own work
|
|
|
|
If the work you are contributing is 100% your own, Zulip doesn't require you to
|
|
sign a copyright assignment or a contributor license agreement for your
|
|
contribution. As noted [in the GitHub Terms of
|
|
Service](https://docs.github.com/en/site-policy/github-terms/github-terms-of-service#6-contributions-under-repository-license):
|
|
|
|
> “Whenever you add Content to a repository containing notice of a license, you
|
|
> license that Content under the same terms, and you agree that you have the
|
|
> right to license that Content under those terms... This is widely accepted as
|
|
> the norm in the open-source community; ...”
|
|
|
|
## Contributing someone else's work
|
|
|
|
If any part of your contribution is from someone else (code snippets, images,
|
|
sounds, or any other copyrightable work, modified or unmodified), you need to
|
|
check whether it was distributed under an open-source license that is
|
|
[compatible][wiki-compatibility] with the [Apache 2.0
|
|
license](https://github.com/zulip/zulip/blob/main/LICENSE). If it was not, this
|
|
work cannot be contributed to Zulip, with or without modification.
