[liangyuanpeng]

create a issue to request add a language for show the language tab on github, and I think the KCL official staff may be the right person to submit the issue.

Yes, that's a great idea, but there are strict conditions for highlighting on GitHub: https://github.com/github-linguist/linguist/blob/master/CONTRIBUTING.md#adding-an-extension-to-a-language
In short, we will continue to work hard and highlighting on GitHub is one of the important milestones for the community.
