-The JuMP community strongly values inclusivity and diversity. Everyone should
-treat others with the utmost respect. Everyone in the community must adhere to
-the [NumFOCUS Code of Conduct](https://numfocus.org/code-of-conduct) and the
-[Julia Community Standards](https://julialang.org/community/standards/), which
-reflect the values of our community. Both these links have information on how to

+## NumFOCUS Code of Conduct
+
+The NumFOCUS Code of Conduct applies in all spaces managed by JuMP, such as 
+JuMP GitHub repositories and JuMP-organized events.
+
+You can find the whole document here https://numfocus.org/code-of-conduct.
+
+### The short version
+
+NumFOCUS is dedicated to providing a harassment-free community for everyone,
+regardless of gender, sexual orientation, gender identity and expression,
+disability, physical appearance, body size, race, or religion. We do not
+tolerate harassment of community members in any form.
+
+Be kind to others. Do not insult or put down others. Behave professionally.
+Remember that harassment and sexist, racist, or exclusionary jokes are not
+appropriate for NumFOCUS.
+
+All communication should be appropriate for a professional audience including
+people of many different backgrounds. Sexual language and imagery is not
+appropriate.
+
+Thank you for helping make this a welcoming, friendly community for all.
+
+### The long version
+
+You can find the long version of the Code of Conduct on the NumFOCUS website
