GitHub Pages are public web pages for users,
organizations, and repositories, that are freely hosted on GitHub's github.io
domain or on a custom domain name of your choice. GitHub Pages are powered by
Jekyll behind the scenes, so they're a great way to host your Jekyll-powered
website for free.
Your site is automatically generated by GitHub Pages when you push your source files. Note that GitHub Pages works equally well for regular HTML content, simply because Jekyll treats files without front matter as static assets. So if you only need to push generated HTML, you're good to go without any further setup.
The GitHub Pages Documentation is comprehensive and includes a a guide to setting up a GitHub Pages site using Jekyll. We recommend following this guide.
This page contains some additional information which may be useful when working on GitHub Pages sites with Jekyll.
<div class="note"> <h5>GitHub Pages Documentation, Help, and Support</h5> <p> For more information about what you can do with GitHub Pages, as well as for troubleshooting guides, you should check out <a href="https://docs.github.com/en/free-pro-team@latest/github/working-with-github-pages">GitHub’s Pages Help section</a>. If all else fails, you should contact <a href="https://github.com/contact">GitHub Support</a>. </p> </div>Sometimes it's nice to preview your Jekyll site before you push your gh-pages
branch to GitHub. The subdirectory-like URL structure GitHub uses for
Project Pages complicates the proper resolution of URLs. In order to assure your
site builds properly, use the handy [URL filters]({{ '/docs/liquid/filters/' | relative_url }}):
{% raw %}
<!-- For styles with static names... -->
<link href="{{ 'assets/css/style.css' | relative_url }}" rel="stylesheet">
<!-- For documents/pages whose URLs can change... -->
[{{ page.title }}]("{{ page.url | relative_url }}")
{% endraw %}
This way you can preview your site locally from the site root on localhost,
but when GitHub generates your pages from the gh-pages branch all the URLs
will resolve properly.
GitHub Pages work by looking at certain branches of repositories on GitHub. There are two basic types available: user/organization and project pages. The way to deploy these two types of sites are nearly identical, except for a few minor details.
User and organization pages live in a special GitHub repository dedicated to
only the GitHub Pages files. This repository must be named after the account
name. For example, @mojombo’s user page repository has the name
mojombo.github.io.
Content from the master branch of your repository will be used to build and
publish the GitHub Pages site, so make sure your Jekyll site is stored there.
Unlike user and organization Pages, Project Pages are kept in the same
repository as the project they are for, except that the website content is
stored in a specially named gh-pages branch or in a docs folder on the
master branch. The content will be rendered using Jekyll, and the output
will become available under a subpath of your user pages subdomain, such as
username.github.io/project (unless a custom domain is specified).
The Jekyll project repository itself is a perfect example of this branch structure—the [master branch]({{ site.repository }}) contains the actual software project for Jekyll, and the Jekyll website that you’re looking at right now is contained in the [docs folder]({{ site.repository }}/tree/master/docs) of the same repository.
Please refer to GitHub official documentation on user, organization and project pages to see more detailed examples.

For that we can use certain CLI options to make the workflow hassle-free.
bundle exec jekyll serve --baseurl=""
This will run the jekyll server on your local machine i.e. on http://localhost:4000. Refer <a href="{{ '/docs/configuration/options/#serve-command-options' | relative_url }}">server options</a> for available options.
