 Want to contribute? Great!

 ### Larger changes
+
 Before you start working on a larger contribution, you should get in touch with
 us first through the issue tracker with your idea so that we can help out and
 possibly guide you. Coordinating up front makes it much easier to avoid
 frustration later on.
 
 ### Code reviews

 All submissions, including submissions by project members, require review. We
 use Github pull requests for this purpose.
 
 ### Browser compatibility
-We care strongly about making Blockly work on all browsers.  As of 2017 we 
-support IE 10 and 11, Edge, Chrome, Safari, and Firefox.  We will not accept
