wtf is spin-developer?

This repository holds the source code for the Fermyon developer website, which lives at developer.fermyon.com. It's essentially the blueprint and content source for a public-facing documentation site where developers go to learn about Fermyon's tools and how to build with them. At a high level, the project is a website built with standard web technologies. It relies on npm and Node.js, which are common foundational tools for managing and running JavaScript projects. To build and run the site, it uses a tool called Spin. Spin acts as the engine that serves the web pages so you can view them in a browser. When someone is working on the site locally, they use a specific Spin command that watches for changes, meaning if you edit a paragraph or a page, the site automatically refreshes so you can see your updates instantly without having to manually restart anything. The primary audience for this repo consists of developers or technical writers who want to contribute to Fermyon's official documentation. For example, if a developer figured out a clever way to use Fermyon's tools and wanted to share that knowledge, or if they noticed a typo or outdated instruction in the official guides, they would use this repository to make those changes. The repository provides the instructions needed to copy the site onto their own computer, make their edits, and eventually submit those improvements to the live public website. The README is quite sparse and doesn't go into detail about the underlying architecture or any notable technical tradeoffs. Beyond the basic setup commands and a pointer to a "Contributing to Docs" guide, it simply serves as a starting point for getting the website running on a local machine.
