+# Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and
+maintainers pledge to make participation in our project and our community a
+harassment-free experience for everyone, regardless of age, body size, disability,
+ethnicity, sex characteristics, gender identity and expression, level of experience,
+education, socio-economic status, nationality, personal appearance, race, religion,
+or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+- Using welcoming and inclusive language
+- Being respectful of differing viewpoints and experiences
+- Gracefully accepting constructive criticism
+- Focusing on what is best for the community
+- Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+- The use of sexualized language or imagery and unwelcome sexual attention or
+  advances
+- Trolling, insulting/derogatory comments, and personal or political attacks
+- Public or private harassment
+- Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+- Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project team members are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in response to
+any instances of unacceptable behavior.
+
+Project team members have the right and responsibility to remove, edit, or reject
+comments, commits, code, and other contributions that are not aligned to this
+Code of Conduct, or to ban temporarily or permanently any contributor for other
+behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies within all project spaces, and it also applies when an
+individual is representing the project or its community in public spaces. Examples of
+representing a project or community include using an official project e-mail address,
+appearing as a project maintainer, or acting as an appointed representative at an online
+or offline event. Representation of a project may be further defined and clarified by
+the project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by
+contacting the project team at mex@rki.de. All complaints will be reviewed and
+investigated and will result in a response that is deemed necessary and appropriate to
+the circumstances. The project team is obligated to maintain confidentiality with regard
+to the reporter of an incident. Further details of specific enforcement policies may be
+posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may
+face temporary or permanent repercussions as determined by project, departmental
+or organizational leadership roles.
