What is docs.vagrantup.com?

This repository holds the source files for the Vagrant documentation website. Vagrant is a tool that helps developers create and manage consistent, repeatable development environments across different computers. The docs site you visit in your browser is built entirely from the content and code stored here, so any typo fix or new article you contribute here will eventually show up on the live site for everyone to read. The project uses a tool called Middleman, which takes a collection of source files, plain text articles, styles, and scripts, and stitches them together into a finished, static website. "Static" means the server just hands back pre-built pages instead of generating them on the fly each time someone visits. The finished site is hosted on Heroku and then delivered to readers through a service called Fastly, which caches pages around the world so they load quickly no matter where you are. The audience for this repo is twofold. First, anyone reading the Vagrant docs benefits, a developer setting up their first Vagrant box, a team lead documenting how their project's environment works, or a beginner troubleshooting an error message can all find answers on the published site. Second, anyone who spots a typo, a broken link, or an outdated instruction can open an issue or submit a pull request just like any normal GitHub project. You don't need to be a Vagrant expert to fix a sentence or improve the formatting. If you want to preview your changes before submitting them, you can run the site on your own machine. After downloading the repo, two simple commands start a local web server, and you can view the site in your browser at a localhost address. One small quirk noted in the README: some navigation links may require you to add ".html" to the end of the URL to load properly when running locally. That's a minor rough edge in the local preview, not something visitors to the live site would encounter.
