The command "jekyll serve" is used to build and serve a Jekyll website locally on your computer for development and testing purposes.
Jekyll is a static site generator, which means it takes a set of text files and converts them into a complete HTML website. It is commonly used for creating blogs, documentation websites, and other types of simple websites.
When you run the "jekyll serve" command, it initializes the Jekyll environment in your project directory and starts a local web server. It builds your website from the source files and makes it available at a specific address, usually http://localhost:4000/. The "serve" option also watches for any changes you make to your source files and automatically regenerates the website, allowing you to preview those changes in real-time without having to manually rebuild the site each time.
In summary, running "jekyll serve" is a quick and convenient way to build and serve your Jekyll site locally, allowing you to view and test it in a web browser on your computer before deploying it to a live server.
