Introduction

In my recent article, I wrote a guide on how to build a documentation site using Docsify and Github pages. Today, you will learn how to build your site with MkDocs, as we have numerous static site generators(SSG) you can leverage.

Static site generators make building documentation sites easy. MkDocs is an SSG for creating documents as code. It has beautiful features and is easy to use, even for beginners.

This article will teach you about MkDocs, installation, writing documentation, customization, and deploying documentation using Cloudflare pages.
