+## clang-tidy
+
+clang-tidy is a tool that can be used to identify coding style violations, bad
+design patterns, and bug prone contructs.  It's not guaranteed that all tests
+pass, but ideally should be run on new code to find issues.  To run, make sure
+you have clang++-9 installed, and clang-tidy-9 installed, and run.  the -checks
+field can be modified to enable or disable which clang-tidy checks are run.
+The below enables everything in the cert namespace.
+
+```
+mkdir build
+cd build
+cmake .. -DCMAKE_CXX_COMPILER=clang++-9 -DCMAKE_EXPORT_COMPILE_COMMANDS=ON
+make -j
+run-clang-tidy-9 -p . -header-filter=".*" -checks="-*,cert-*"
