+      <h2>What is CBOR?</h2>
+      <p>CBOR (Concise Binary Object Representation) is a binary data format that aims to be smaller and more efficient
+        than JSON. It provides a compact binary representation of structured data, making it useful for scenarios where
+        size and performance are important.</p>
