I found that the latest version of GitHub(Beta) already supports Chinese.
I am very happy to be able to use Chinese on GitHub, thank you!
But there is a problem: Google Play Store is not available in Mainland China.
So many people cannot download GitHub for mobile(Android).
Do you have any plans to release GitHub for mobile(Android) in Mainland China?
As far as I know, Microsoft uses coolapk.com as its distribution channel for Microsoft Launcher in Mainland China, maybe you can follow them.
