+        <p>This component demonstrates usage of the <a href="https://github.com/electrode-io/electrode-csrf-jwt">electrode-csrf-jwt</a> module. Two endpoints are declared in <code>server/plugins/demo.js</code>:</p>
+        <ul>
+          <li>a GET endpoint, <code>/1</code>, to which the module automatically adds a csrf token header</li>
+          <li>a POST endpoint, <code>/2</code>, to which the module automatically ensures the presence of a valid token in the request headers</li>
+        </ul>
+        <p>Two simple tests via AJAX (JavaScript must be enabled) are demonstrated below:</p>
+        <ul>
+          <li><a href="#" onClick={this.testValid}>Test Valid POST</a> using a token retrieved from <code>/1</code> first (should succeed with a 200 status)</li>
+          <li><a href="#" onClick={this.testInvalid}>Test Invalid POST</a> using a forged token (should fail with a 400 status)</li>
