## Join a SIG or start your own

CentOS Special Interest Groups (SIGs) are smaller groups within the CentOS community
that focus feature work on or awareness around a topic related to CentOS Stream.

There are SIGs with very different goals, such as deployment at a masive scale,
making alternative CentOS Stream images (including KDE Live),
immutable CoreOS builds, and many more.

See the list of active [CentOS SIGs](/sigs) and learn more about SIGs in general in the
[CentOS SIG Guide](https://docs.centos.org/centos-sig-guide/).


## Test and contribute to CentOS Stream

CentOS Stream is a Linux distribution built by Red Hat Enterprise Linux (RHEL) engineers
as part of public RHEL development.
It's used by RHEL customers in CI and to preview what's coming to the next minor RHEL version,
as a contribution path to RHEL itself, and as a base for CentOS SIGs.

You can test your applications in CI and [report bugs to CentOS Stream](/bugs).

Or even learn how to
[contribute to CentOS Stream](https://docs.centos.org/centos-stream-docs/contributors-guide/)
and contribute code directly.

## Join the EPEL effort

[EPEL](https://docs.centos.org/centos-stream-docs/contributors-guide/) -
Extra Packages for Enterprise Linux - is a Fedora Special Interest Group that creates,
maintains, and manages a high quality set of additional packages for Enterprise Linux,
including, but not limited to, Red Hat Enterprise Linux (RHEL) and CentOS.
Getting involved in EPEL is a great way to make CentOS more useful.
