+  <h2>What is FreeDOI?</h2>
+  <p>
+    FreeDOI is an alternative DOI system that allows users to create and manage
+    DOIs for various types of digital content. Our system uses a range of
+    prefixes (20. to 29.) to categorize different fields, such as:
+  </p>
+  <ul>
+    <li><strong>20.</strong> Science / Research</li>
+    <li><strong>21.</strong> Software</li>
+    <li><strong>22.</strong> Entertainment</li>
+  </ul>
+  <p>
+    FreeDOI also supports resolving official DOI prefixes (10.) to access
+    content from the official DOI system.
+  </p>
+
+  <h2>How Does It Work?</h2>
+  <p>
+    FreeDOI provides a simple and intuitive interface for creating and managing
+    DOIs. Here's how you can get started:
