 Then run clang-tidy on your local changes:
 
 ```

 ```
 
 This will check all source files in the `src`, `include` and `tests` directories using the compile commands from your `build` directory.
 If you wish to automatically fix whatever clang-tidy finds _and_ is capable of fixing, add `-fix` to the above command:
