# Contributing
We welcome contributions from everyone. However, please follow the following guidelines when posting a GitHub Pull Request or filing a GitHub Issue on the systemd project:
## Filing Issues
-* We use GitHub Issues **exclusively** for tracking **bugs** and **feature** **requests** of systemd. If you are looking for help, please contact our [mailing list](https://lists.freedesktop.org/mailman/listinfo/systemd-devel) instead.
-* We only track bugs in the **two** **most** **recently** **released** **versions** of systemd in the GitHub Issue tracker. If you are using an older version of systemd, please contact your distribution's bug tracker instead.

+* We only track bugs in the **two** **most** **recently** **released** (non-rc) **versions** of systemd in the GitHub Issue tracker. If you are using an older version of systemd, please contact your distribution's bug tracker instead (see below). See [GitHub Release Page](https://github.com/systemd/systemd/releases) for the list of most recent releases.
* When filing an issue, specify the **systemd** **version** you are experiencing the issue with. Also, indicate which **distribution** you are using.
* Please include an explanation how to reproduce the issue you are pointing out.
## Security vulnerability reports
-If you discover a security vulnerability, we'd appreciate a non-public disclosure. The issue tracker and mailing list listed above are fully public. If you need to reach systemd developers in a non-public way, report the issue in one of the "big" distributions using systemd: [Fedora](https://bugzilla.redhat.com/enter_bug.cgi?product=Fedora&component=systemd) (be sure to check "Security Sensitive Bug" under "Show Advanced Fields"), [Ubuntu](https://launchpad.net/ubuntu/+source/systemd/+filebug) (be sure to change "This bug contains information that is" from "Public" to "Private Security"), or [Debian](mailto:security@debian.org). Various systemd developers are active distribution maintainers and will propagate the information about the bug to other parties.
+See [reporting of security vulnerabilities](SECURITY.md).
## Posting Pull Requests
* Make sure to post PRs only relative to a very recent git master.
-* Follow our [Coding Style](https://raw.githubusercontent.com/systemd/systemd/master/docs/CODING_STYLE) when contributing code. This is a requirement for all code we merge.
-* Please make sure to test your change before submitting the PR. See [HACKING](https://raw.githubusercontent.com/systemd/systemd/master/docs/HACKING) for details how to do this.
+* Follow our [Coding Style](CODING_STYLE.md) when contributing code. This is a requirement for all code we merge.
+* Please make sure to test your change before submitting the PR. See the [Hacking guide](HACKING.md) for details on how to do this.
* Make sure to run the test suite locally, before posting your PR. We use a CI system, meaning we don't even look at your PR, if the build and tests don't pass.
* If you need to update the code in an existing PR, force-push into the same branch, overriding old commits with new versions.
* After you have pushed a new version, add a comment about the new version (no notification is sent just for the commits, so it's easy to miss the update without an explicit comment). If you are a member of the systemd project on GitHub, remove the `reviewed/needs-rework` label.
