 Based on [LSIF](https://microsoft.github.io/language-server-protocol/overviews/lsif/overview/), diffctx will not only
 analyse the lines contained by the diff, but also the full scope of your repo, and understand it well.

 ### Done!
 
 You can create a new PullRequest for test.
 
-### What about other languages?
-
-Currently, diffctx can also support java/kotlin.
-But you have to generate LSIF file ([this link](https://github.com/williamfzc/diffctx/blob/main/index.py) might help) by
-yourself because of the complexity of the compilation process.

-```yml
