manen repository home page

In readme

net.devh
grpc-spring-boot-starter
2.15.0.RELEASE

But in the maven repository this artifact https://mvnrepository.com/artifact/net.devh/grpc-spring-boot-starter/2.15.0.RELEASE has a different home page https://github.com/yidongnan/grpc-spring -boot-starter
Also in the code there are many links to the fork from yidongnan, and not to the original grpc-ecosystem repository.

But the yidongnan project is in the archive.

Explain what is the difference between these repositories?
Which one will be supported?

Start with the README dependency block and compare its project link with the Maven Repository entry. Then inspect the repository links mentioned in the issue and document the relationship between the two repositories and which project is supported; the issue is complete when those points are clarified.
