C/C++ - Questions for header file usage instructions.

[good-riverdeer]

Hello, First of all, thank you for the update ClangdLanguageServer. This update is a great help to many C/C++ developers.

As you know, many developers work with header files included in their projects. I would appreciate information on how to include and use these header files. If you could provide detailed explanations or examples on how to include header files, it would be very beneficial for me and other developers.

Thank you!
