This tutorial explains how to easily migrate a GitHub Pages site to Netlify, a popular platform for hosting and deploying websites. The process involves installing the Netlify CLI tool, creating a new site with `netlify create`, deploying the site with `netlify deploy`, and viewing it in the browser. To set up continuous delivery, you can use the `netlify init` command to add webhooks for GitHub. Once migrated, your site will be live on Netlify's global CDN and tied to your Git repository. The process is straightforward, allowing users to easily switch from GitHub Pages to Netlify with just a few commands.
