-## When something happens
+## Our Pledge
 
-If you see a violation of our community's standards of [Conduct](#conduct), follow these steps:
+We as members, contributors, and leaders pledge to make participation in our community a harassment-free experience for everyone, regardless of age, body size, visible or invisible 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.
 
-1. Let the person know that what they did is not appropriate and ask them to stop and/or edit their messages.
-2. That person should immediately stop the behavior and correct the issue.
-3. If this doesn’t happen, or if you're uncomfortable speaking up, contact the maintainers.
-4. As soon as available, a maintainer will look into the issue, and take further action, starting with a warning, then temporary block, then long-term repo or organization ban.
+We pledge to act and interact in ways that contribute to an open, welcoming, diverse, inclusive, and healthy community.
 
-When reporting, please include any relevant details, links, screenshots, context, or other information that may be used to better understand and resolve the situation.

-The maintainers will prioritize the well-being and comfort of the recipients of the violation over the comfort of the violator.

-## Conduct
+## Our Standards
 
 In this community we strive to go the extra step to look out for each other. Don’t just aim to be technically unimpeachable, try to be your best self. In particular, avoid flirting with offensive or sensitive issues, particularly if they’re off-topic; this all too often leads to unnecessary fights, hurt feelings, and damaged trust; worse, it can drive people away from the community entirely.
 
 And if someone takes issue with something you said or did, resist the urge to be defensive. Just stop doing what it was they complained about and apologize. Even if you feel you were misinterpreted or unfairly accused, chances are good there was something you could’ve communicated better — remember that it’s your responsibility to make your fellow Rustaceans comfortable. Everyone wants to get along and we are all here first and foremost because we want to talk about cool technology. You will find that people will be eager to assume good intent and forgive as long as you earn their trust.
 
-* We are committed to providing a friendly, safe and harassment-free environment for all, regardless of level of experience, gender identity and expression, sexual orientation, disability, personal appearance, body size, race, ethnicity, age, religion, nationality, or other similar characteristic.
 * Please avoid using overtly sexual aliases or other nicknames that might detract from a friendly, safe and welcoming environment for all.
 * Please be kind and courteous. There’s no need to be mean or rude.
 * Respect that people have differences of opinion and that every design or implementation choice carries a trade-off and numerous costs. There is seldom a right answer.
