+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our
+project and our community a harassment-free experience for everyone,
+regardless of age, body size, disability, ethnicity, gender identity
+and expression, level of experience, 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 maintainers 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 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, 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 both within project spaces and in public
+spaces when an individual is representing the project or its
+community. Examples of representing a project or community include
+using an official project e-mail address, posting via an official
+social media account, or acting as an appointed representative at an
+online or offline event. Representation of a project may be further
+defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior
+may be reported by contacting the project team at
+gergely@polonkai.eu. 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 other members of the project's leadership.
