 .git/hooks and make sure that it is executable.  The pre-commit script
 uses clang-format-diff.py to detect any style errors.  If it is not in
 your PATH or it exists under different name (e.g.,
-clang-format-diff-12 in debian), either add it to PATH variable or add
+clang-format-diff-14 in debian), either add it to PATH variable or add
 git option ``clangformatdiff.binary`` to point to the script.
 
 For emacs users, integrating clang-format to emacs is very easy.
 clang-format.el should come with clang distribution.  If it is not
 found, download it from `here
