-# Contributor Covenant Code of Conduct
+This is our Code of Conduct and Ethics (the “Code”)
 
-## Our Pledge
+It is based on our values and aspirations (be good, innovate, work together, be part of the solution). It describes what we expect from the members of the community in three main rules:
 
-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, 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
-
-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.
-
-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 Technical Advisory Board (TAB) at
-<tab@metta.systems>. All complaints will be reviewed and
-investigated and will result in a response that is deemed necessary and
-appropriate to the circumstances. The TAB is obligated to maintain
-confidentiality with regard to the reporter of an incident.  Further details of
-specific enforcement policies may be posted separately.
-
-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.
-
-## Attribution
-
-This Code of Conduct is adapted from the Contributor Covenant, version 1.4, available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html
+1. Do the right thing. Always act with honesty, integrity, and reliability. Keep moral and ethical standards high.
+2. Be nice. Treat people with dignity and respect, regardless of who they are and where they came from. Stay decent and courteous in all relationships.
+3. Play fair. Don’t cheat. Be careful to account for and balance the interests of all groups (developers, artists and designers, end users and the general public).
