+Code of Conduct
+-------------------
+
+Trust, partnership, simplicity and passion are our core values we live and 
+breathe in our daily work life and within our projects. Our open-source 
+projects are no exception. We have an active community which spans the globe 
+and we welcome and encourage participation and contributions to our projects 
+by everyone. We work to foster a positive, open, inclusive and supportive 
+environment and trust that our community respects the micro:bit code of conduct. 
+
+Please see our [code of conduct](https://microbit.org/safeguarding/) which 
+outlines our expectations for all those that participate in our community and 
+details on how to report any concerns and what would happen should breaches occur.
