+# Kubermatic Community Code of Conduct
+
+## Contributor Code of Conduct
+
+As contributors and maintainers of this project, and in the interest of fostering
+an open and welcoming community, we pledge to respect all people who contribute
+through reporting issues, posting feature requests, updating documentation,
+submitting pull requests or patches, and other activities.
+
+We are committed to making participation in this project a harassment-free experience for
+everyone, regardless of level of experience, gender, gender identity and expression,
+sexual orientation, disability, personal appearance, body size, race, ethnicity, age,
+religion, or nationality.
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery
+* Personal attacks
+* Trolling or insulting/derogatory comments
+* Public or private harassment
+* Publishing others' private information, such as physical or electronic addresses,
+  without explicit permission
+* Other unethical or unprofessional conduct.
+
+Project maintainers have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are not
+aligned to this Code of Conduct. By adopting this Code of Conduct, project maintainers
+commit themselves to fairly and consistently applying these principles to every aspect
+of managing this project. Project maintainers who do not follow or enforce the Code of
+Conduct may be permanently removed from the project team.
+
+This code of conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community.
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the Kubermatic Conduct Committee via [email protected].
+
+This Code of Conduct is adapted from the [CNCF Code of Conduct](https://github.com/cncf/foundation/blob/main/code-of-conduct.md) and [Contributor Covenant](http://contributor-covenant.org/version/1/2/0/), version 1.2.0.

+# How to Contribute
+
+Kubermatic projects are [Apache 2.0 licensed](LICENSE) and accept contributions via
+GitHub pull requests. This document outlines some of the conventions on
+development workflow, commit message formatting, contact points and other
+resources to make it easier to get your contribution accepted.
+
+## Certificate of Origin
+
+By contributing to this project you agree to the Developer Certificate of
+Origin (DCO). This document was created by the Linux Kernel community and is a
+simple statement that you, as a contributor, have the legal right to make the
+contribution. See the [DCO](DCO) file for details.
+
+Any copyright notices in this repo should specify the authors as "the Kubermatic Developer Platform project contributors".
+
+To sign your work, just add a line like this at the end of your commit message:
+
+```
+Signed-off-by: Joe Example <[email protected]>
+```
+
+This can easily be done with the `--signoff` option to `git commit`.
+
+Note that we're requiring all commits in a PR to be signed-off. If you already created a PR, you can sign-off all existing commits by rebasing with the `--signoff` flag.
+
+```
+git rebase --signoff origin/main
+```
+
+By doing this you state that you can certify the following (from https://developercertificate.org/):
+```
+Developer Certificate of Origin
+Version 1.1
+
+Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
+1 Letterman Drive
+Suite D4700
+San Francisco, CA, 94129
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+
+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.
+```
+
+## Email and Chat
+
+The XXX project currently uses the general Kubermatic email list and Slack channel:
+- Email: [kubermatic-dev](https://groups.google.com/forum/#!forum/kubermatic-dev)
+- Slack: #[Slack](http://slack.kubermatic.io/) on Slack
+
+Please avoid emailing maintainers found in the MAINTAINERS file directly. They
+are very busy and read the mailing lists.
+
+## Reporting a security vulnerability
+
+Due to their public nature, GitHub and mailing lists are not appropriate places for reporting vulnerabilities. If you suspect you have found a security vulnerability, please do not file a GitHub issue, but instead email [email protected] with the full details, including steps to reproduce the issue.
+
+## Getting Started
+
+- Fork the repository on GitHub
+- Read the [README](README.md) for build and test instructions
+- Play with the project, submit bugs, submit patches!
+
+### Contribution Flow
+
+This is a rough outline of what a contributor's workflow looks like:
+
+- Create a topic branch from where you want to base your work (usually main).
+- Make commits of logical units.
+- Make sure your commit messages are in the proper format (see below).
+- Push your changes to a topic branch in your fork of the repository.
+- Make sure the tests pass, and add any new tests as appropriate.
+- Submit a pull request to the original repository.
+
+Thanks for your contributions!
