Don't worry, this is not a reaction to some disaster within the Angular community.
We're grateful that the Angular community is filled with really nice people. We've become a huge and diverse group. A set of written guidelines will help maintain the high level of discourse in all of our communications. Also we made Angular to help everyone build great apps so we want to explicitly state that everyone is welcome.
The code of conduct is a short document that describes the expectations we have about how we communicate within the Angular community. Please read and follow it.
If you are running an Angular event (meetup, user group, etc.), please have a code of conduct for it.
If you have questions or concerns regarding the code of conduct, you can now email email@example.com.
