 Usually C/C++ language extensions rely on a file called ``compile_commands.json``, which is located in your project build directory. You can generate this file using the ``ESP-IDF: Run idf.py reconfigure task``.
 
-For LLVM clangd extension, only ``compile_commands.json`` is needed. For Microsoft C/C++ extension, a configuration file is located at ``{PROJECT_DIRECTORY_PATH}/.vscode/c_cpp_properties.json``. This file can be generated by creating a project using ``ESP-IDF: New Project``, ``ESP-IDF: Show Example Projects`` command, or by using the ``ESP-IDF: Add .vscode Configuration Folder`` command on an existing ESP-IDF projects.
+For `LLVM clangd extension <https://marketplace.visualstudio.com/items?itemName=llvm-vs-code-extensions.vscode-clangd>`_, the user can use the ``ESP-IDF: Configure project for ESP-Clang`` to configure this extension argument.
+The command will search for ``esp-clang`` in the configured ESP-IDF setup, the build directory from ``idf.buildPath`` (``idf.buildPathWin`` in Windows) and the GCC toolchain path from current ``IDF_TARGET`` and configured ESP-IDF setup and use these paths to configure clang path and arguments.
