| 5 | --- - **NOTE:** Clang >= 11 is recommended! See [#23](https://github.com/neovim/nvim-lspconfig/issues/23). |
| 6 | --- - If `compile_commands.json` lives in a build directory, you should |
| 7 | --- symlink it to the root of your source tree. |
| 8 | --- ``` |
| 9 | --- ln -s /path/to/myproject/build/compile_commands.json /path/to/myproject/ |
| 10 | --- ``` |
| 11 | --- - clangd relies on a [JSON compilation database](https://clang.llvm.org/docs/JSONCompilationDatabase.html) |
| 12 | --- specified as compile_commands.json, see https://clangd.llvm.org/installation#compile_commandsjson |
