How to run a local server
You can view clone the demo project here: https://github.com/mmagnusen/boilerplate
Navigate to the root of the project and run:
npx serve
This will work as it is, without needing to manually install any packages.
If the serve command isn't already in your $PATH, npx will install the module and run it.

You can visit the served site at the destination indicated, by clicking directly on the link within the terminal.
