 After building your project, CMake will generate the `compile_commands.json` file in the build directory and clangd will automatically pick it up.

+## Debugging
+
+You can use CodeLLDB or GDB to debug native binaries. (Make sure that your build process passes `-g` to the C compiler, so that debug information is included in the resulting binary.) See below for examples of debug configurations that you can add to `.zed/debug.json`.
