Dear Makecode Team,  
I create an extension board for microbit like this:

 ![88114365_778225289335543_8670875204903239680_n](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/1X/5c2b035bff7c23f08fca597436716e4f80d94930.jpeg)  
And I was building a new editor from pxt-microbit in my server.  
But I can’t modify or add a new package(extension) to my editor(I add a new package to folder pxt-common-package/libs or pxt-microbit/libs but I wasn’t run)

Kindly respond and let me know how to add the package for developing new editor.  
Thanks you very much.

Best regard,
