 ### Code of Conduct
 
-This Code of Conduct is adapted from [Rust's wonderful
-CoC](https://github.com/rust-lang/rust/wiki/Note-development-policy#conduct).
-
-* We are committed to providing a friendly, safe and welcoming
-  environment for all, regardless of gender, sexual orientation,
-  disability, ethnicity, religion, or similar personal characteristic.
-* Please avoid using overtly sexual nicknames 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.
-* Please keep unstructured critique to a minimum. If you have solid
-  ideas you want to experiment with, make a fork and see how it works.
-* We will exclude you from interaction if you insult, demean or harass
-  anyone.  That is not welcome behaviour. We interpret the term
-  "harassment" as including the definition in the [Citizen Code of
-  Conduct](http://citizencodeofconduct.org/); if you have any lack of
-  clarity about what might be included in that concept, please read
-  their definition. In particular, we don't tolerate behavior that
-  excludes people in socially marginalized groups.
-* Private harassment is also unacceptable. No matter who you are, if
-  you feel you have been or are being harassed or made uncomfortable
-  by a community member, please contact one of the channel ops or any
-  of the TC members immediately with a capture (log, photo, email) of
-  the harassment if possible.  Whether you're a regular contributor or
-  a newcomer, we care about making this community a safe place for you
-  and we've got your back.
-* Likewise any spamming, trolling, flaming, baiting or other
-  attention-stealing behaviour is not welcome.
-* Avoid the use of personal pronouns in code comments or
-  documentation. There is no need to address persons when explaining
-  code (e.g. "When the developer")
