            <p>This interactive emulator allows you to experience Plan 9 from Bell Labs directly in your browser. Plan 9 was developed in the late 1980s and early 1990s as a research successor to UNIX by many of the same people, including Ken Thompson, Rob Pike, and Dave Presotto.</p>

                <h3>Using the Plan 9 Emulator</h3>
                <p>Once the emulator loads, you'll see the Plan 9 graphical interface:</p>
                <ul>
                    <li>Use your mouse to interact with the system</li>
                    <li>Right-click opens contextual menus</li>
                    <li>Middle-click (or scroll wheel click) for text operations</li>
                    <li>The emulator runs entirely in your browser - no data is saved between sessions</li>
                </ul>
