+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.
+
+More specifically, the created site:
+
+- uses a gem-based approach, i.e. uses a `Gemfile` and loads the `just-the-docs` gem
+- uses the [GitHub Pages / Actions workflow] to build and publish the site on GitHub Pages
+
+Other than that, you're free to customize sites that you create with this template, however you like. You can easily change the versions of `just-the-docs` and Jekyll it uses, as well as adding further plugins.
+
+[Browse our documentation][Just the Docs] to learn more about how to use this theme.
+
+To get started with creating a site, simply:
+
+1. click "[use this template]" to create a GitHub repository
+2. go to Settings > Pages > Build and deployment > Source, and select GitHub Actions
+
+If you want to maintain your docs in the `docs` directory of an existing project repo, see [Hosting your docs from an existing project repo](https://github.com/just-the-docs/just-the-docs-template/blob/main/README.md#hosting-your-docs-from-an-existing-project-repo) in the template README.
+
+----
+
+[^1]: [It can take up to 10 minutes for changes to your site to publish after you push the changes to GitHub](https://docs.github.com/en/pages/setting-up-a-github-pages-site-with-jekyll/creating-a-github-pages-site-with-jekyll#creating-your-site).
