+        
+        <h5>Chat Only</h5>
+        <div class="uncloseai" data-features="chat"></div>
+

         <p>This web client-only solution uses <a href="https://uncloseai.com/uncloseai.js" target="_blank">uncloseai.js</a> to make the browser act as a client, directly interacting with the API without needing an intermediary server. By eliminating the need for a valid API key, the API handles requests on behalf of the browser client, making it efficient and accessible thin client, especially those on battery power like phones & laptops.</p>

-	<p>A stand alone demo is here: <a href="https://ai.unturf.com/demo.html">uncloseai.js demostration</a></p>
+        <h3>Installing uncloseai.js on Your Website</h3>
+        
+        <p>Add AI capabilities to any static website or web application with just one line of code. uncloseai.js automatically creates a floating "uncloseai." button that provides access to Hermes AI, text-to-speech, file upload, and more.</p>
+        
+        <h4>Quick Installation</h4>
+        <p>Add this script tag to your HTML - that's it! The floating AI button appears automatically:</p>
+        <pre><code class="html">&lt;script src="https://uncloseai.com/uncloseai.js" type="module"&gt;&lt;/script&gt;</code></pre>
+        
+        <h4>Configuration Options</h4>
+        <p>To use your CSS framework's styling instead of uncloseai.js custom styles:</p>
+        <pre><code class="javascript">&lt;script&gt;
+    window.UNCLOSEAI_CUSTOM_STYLING = false;
+&lt;/script&gt;</code></pre>
+        
+        <p>To disable the floating button (if you only want the API functions):</p>
+        <pre><code class="javascript">&lt;script&gt;
+    window.UNCLOSEAI_SHOW_BUTTON = false;
+&lt;/script&gt;</code></pre>
+        
+        <h4>Class-Based Integration</h4>
+        <p>Embed AI features directly into your HTML using CSS classes and data attributes:</p>
+        
+        <p><strong>Full Interface:</strong> Complete AI chat with all features</p>
+        <pre><code class="html">&lt;div class="uncloseai" data-features="full"&gt;&lt;/div&gt;</code></pre>
+        
+        <p><strong>Chat Only:</strong> Just the AI chat interface</p>
+        <pre><code class="html">&lt;div class="uncloseai" data-features="chat"&gt;&lt;/div&gt;</code></pre>
+        
+        <p><strong>Specific Features:</strong> Choose which buttons to include</p>
+        <pre><code class="html">&lt;div class="uncloseai" data-features="tts,upload,read"&gt;&lt;/div&gt;
+&lt;div class="uncloseai" data-features="tts"&gt;&lt;/div&gt;</code></pre>
+        
+        <p><strong>Available Features:</strong> <code>chat</code>, <code>tts</code>, <code>upload</code>, <code>read</code>, <code>full</code></p>
+        
+        <h4>What You Get</h4>
+        <ul>
+            <li><strong>🤖 Floating AI Assistant</strong> - Always-accessible "uncloseai." button in bottom right</li>
+            <li><strong>📖 Page-Aware</strong> - Hermes AI understands your page content and generates contextual introductions</li>
+            <li><strong>🔊 Text-to-Speech</strong> - Convert any text to speech with multiple voice options</li>
+            <li><strong>📁 File Upload</strong> - Upload and discuss documents, images, and more</li>
+            <li><strong>💾 Conversation History</strong> - Persistent chat history with delete functionality</li>
+            <li><strong>🎨 Framework Compatible</strong> - Works with PicoCSS, PureCSS, Bootstrap, and more</li>
+        </ul>
+        
+        <p><strong>Live Demo:</strong> <a href="https://ai.unturf.com/demo.html">Try uncloseai.js in action here</a> - see the floating button and AI features working on a real page!</p>
