Step-Wise Tutorial
Step 1- Install Bootstrap Barrio theme
Step 2- Create a Subtheme
Step 3- Enable the Theme

4. Step 1
While the popular Bootstrap theme on Drupal.org is a great option, it's important to
note that it is based on an older version of Bootstrap (version 3.x).
Since Bootstrap is constantly evolving and introducing new features, it's
recommended to use a theme that is based on the latest version of Bootstrap to take
advantage of its full capabilities.
That's why we've chosen to use the Bootstrap Barrio theme for this tutorial, as it is
built on the latest version of Bootstrap (version 5.x). This theme is designed
specifically for Drupal and offers a range of features and customization options.

7. An Example Customization
With your custom Bootstrap theme set up and enabled, you can begin using it to
create your website or application. To use the Bootstrap library as-is, simply start
creating your website or application, leveraging the various pre-built components
and features provided by Bootstrap.
However, if you want to customize the look and feel of your Bootstrap theme to
better suit your needs, you can do so using the various customization options
available in Drupal and Bootstrap.
