This guide provides a step-by-step tutorial on hosting a website built with Gatsby on Netlify, including setting up continuous deployment. The process involves installing Gatsby globally using the `gatsby-cli` command, creating a new project with the Blog starter, configuring the local directory as a Git repository, and connecting it to Netlify. Once connected, Netlify takes care of building, deploying, and running the site, making it easy to manage and maintain a static website without manual deployment or updates. The guide also covers prepping for build, creating a new site, authorizing Netlify, configuring settings, building the site, and making changes.
