 ## Support
 This repository used to be an extension instead of a package, but now it does **not** work in any MakeCode editor. This is because of the issues that were encountered in pxt.json. So now, review everything here instead. Also, tags and releases will still be updated, so do **not** worry about that. If you have any questions about this repository, please click on this link here.
