+## Code Formatting
+
+We use [this script](/scripts/format.sh#L20) to install a consistent version of [`clang-format`](https://clang.llvm.org/docs/ClangFormat.html) to format the code base. The format is automatically checked via a GitHub Action job as well. Run the following script locally to ensure formatting is ready to merge:
+
+```
+make format
+```
+
+We also use [`clang-tidy`](https://clang.llvm.org/extra/clang-tidy/) as a C++ linter. Run the following command to lint and ensure your code is ready to merge:
+
+```
+make tidy
+```
+
+These commands are set from within [the Makefile](./Makefile).

 # Benchmarks
 
 Benchmarks can be run with the bench/vtquery.bench.js script to test vtquery against common real-world fixtures (provided by mvt-fixtures). When making changes in a pull request, please provide the benchmarks from the master branch and the HEAD of your current branch.  You can control the `concurrency` and `iterations` of the benchmarks with the following command:
