+This repository requires you to install the clang-format command. This hook has
+been tested with clang-format-10, so remove all previous versions and reinstall:
+$ sudo apt-get remove clang-format-*
+$ sudo apt-get install clang-format-10
+You should now have clang-format-10 installed. Then, update the configuration
+as follows:
+$ git config --global clangFormat.binary clang-format-10
+$ git config --global clangFormat.style file
+$ git config --global alias.clang-format clang-format-10
