This is a bare-minimum template to create a Jekyll site that uses the [Just the Docs] theme. You can easily set the created site to be published on [GitHub Pages] – the [README] file explains how to do that, along with other details.
If [Jekyll] is installed on your computer, you can also build and preview the created site locally. This lets you test changes before committing them, and avoids waiting for GitHub Pages.[^1] And you will be able to deploy your local build to a different platform than GitHub Pages.
