+          <p>The complete API documentation is available at <a href="/api/docs">/api/docs</a>.</p>
+          <p>You can also download the OpenAPI specification:</p>
+          <p>

+          <pre>${queryParamsInfo}</pre>
+          
+          <h2>Authentication</h2>
+          <p>This API supports two authentication methods:</p>
+          <ul>
+            <li><strong>Session-based authentication</strong>: Used when accessing the API from the web interface.</li>
+            <li><strong>API Token authentication</strong>: Used when accessing the API programmatically.</li>
+          </ul>
+          
+          <h3>API Token Authentication</h3>
+          <p>To authenticate using an API token, include the token in the Authorization header:</p>
+          <pre>Authorization: Bearer YOUR_API_TOKEN</pre>
+          
+          <h2>Rate Limiting</h2>
+          <p>The API has rate limiting in place to prevent abuse. The current limits are:</p>
+          <ul>
+            <li>100 requests per minute for authenticated users</li>
+            <li>20 requests per minute for unauthenticated users</li>
+          </ul>
+          
+          <h2>Error Handling</h2>
+          <p>The API returns consistent error responses with the following structure:</p>
+          <pre>{
+  "message": "Error message",
+  "errors": [
+    {
+      "path": ["field", "subfield"],
+      "message": "Specific error message"
+    }
+  ]
+}</pre>
