+    <title>ZeroEcho API Library</title>
+</head>
+<body>
+  <p>
+    The ZeroEcho library provides a cohesive and extensible toolkit for secure data processing, cryptographic transformation,
+    and covert communication. Its architecture is centered around composability: data flows through builder-defined pipelines,
+    enabling dynamic combinations of encoding, encryption, formatting, and output strategies.
+  </p>
+
+  <p>
+    ZeroEcho is particularly suited for applications that require secure transmission or obfuscation of binary data in 
+    constrained or adversarial environments - including command-line payload delivery, steganographic embedding,
+    and post-quantum cryptographic operations.
+  </p>
+
+  <h1>Design Principles</h1>
+  <ul>
+    <li><b>Modularity:</b> Each package targets a specific concern (e.g., encryption, data formatting, covert encoding) and is designed for minimal dependencies and high interoperability.</li>
+    <li><b>Security:</b> Cryptographic operations leverage trusted providers (notably Bouncy Castle) and emphasize secure defaults, authenticated encryption, and entropy-aware key handling.</li>
+    <li><b>Builder-Driven APIs:</b> Pipeline construction is managed through fluent builders that abstract away complexity while preserving control.</li>
+    <li><b>Covert &amp; Controlled Output:</b> Support for covert encoding into media formats (like JPEG) and output to script-ready formats (e.g., Base64 in shell wrappers) makes it ideal for discreet or cross-platform delivery.</li>
+  </ul>
+
+  <h1>Key Capabilities</h1>
+  <p>
+    The library includes:
+  </p>
+  <ul>
+    <li>Construction and chaining of content transformations via the <code>builder</code> module</li>
+    <li>Data hiding mechanisms in binary and JPEG images through the <code>covert</code> packages</li>
+    <li>Robust support for AES and asymmetric encryption, password-based key derivation, and post-quantum cryptography via <code>util.aes</code>, <code>util.asymmetric</code>, and <code>util.bc</code></li>
+    <li>Flexible data output in raw, Base64, or platform-specific shell-script forms via <code>data.output</code></li>
+  </ul>
+
+  <p>
+    ZeroEcho aims to bridge high-assurance cryptographic practices with practical concerns around portability,
+    concealment, and controlled delivery - whether in a CLI toolchain, embedded device, or secure messaging layer.
+  </p>
