This is a very simple Laravel Valet driver for serving static sites, specifically ones generated by Hugo. It looks for config.toml, config.yaml, or config.json file in the project root, along with a public folder, to indicate that it should be the active driver. Simply download the HugoValetDriver.php driver and place it in your ~/.config/valet/Drivers directory.
