GitHub has launched a revamped pages.github.com to streamline the process of creating and publishing GitHub Pages sites, making it more accessible for users to host static HTML5, CSS, and JavaScript sites. This update guides users through setting up their first site in minutes, regardless of whether they use Git for the command line, GitHub for Windows, or GitHub for Mac. The site is not only beneficial for newcomers but also offers resources for experienced users to enhance their skills with the Jekyll templating engine and custom domain setups.
