+Enable static code analysis with clang-tidy
+-------------------------------------------
+
+The `clang-tidy tool <https://clang.llvm.org/extra/clang-tidy/>`_ is a
+static code analysis tool to diagnose (and potentially fix) typical
+programming errors or coding style violations.  It has a modular framework
+of tests that can be adjusted to help identifying problems before they
+become bugs and also assist in modernizing large code bases (like LAMMPS).
+It can be enabled for all C++ code with the following CMake flag
+
+.. code-block:: bash
+
+   -D ENABLE_CLANG_TIDY=value    # value = no (default) or yes
+
+With this flag enabled all source files will be processed twice, first to
+be compiled and then to be analyzed. Please note that the analysis can be
+significantly more time consuming than the compilation itself.
