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