-    <h2>What is a Finite State Machine (FSM)?</h2>
-    <ul>
-      <li>
-        A mathematical model of computation that consists of a set of states and
-        transitions between those states.
-      </li>
-      <li>Used to represent systems with a finite number of states.</li>
-      <li>Well-suited for modeling complex game behaviors.</li>
-    </ul>

-  <h2>Why use FSMs in Game Development?</h2>
-  <ul>
-    <li>Improve code organization and readability.</li>
-    <li>Facilitate easier testing and debugging.</li>
-    <li>Enable more flexible and reactive game behaviors.</li>
-    <li>Promote code reusability.</li>
-  </ul>
-</section>
-
-<section>
-  <h2>Introducing XState</h2>
-  <ul>
-    <li>
-      A powerful and flexible state chart library for building complex state
-      machines.
-    </li>
-    <li>
-      Well-suited for game development due to its visual state charts and
-      hierarchical state machines.
-    </li>
-    <li>Provides a declarative approach to state machine design.</li>
-  </ul>
-</section>
-
-<section>
-  <h2>Key Features of XState</h2>
-  <ul>
-    <li>Visual state charts for intuitive design.</li>
-    <li>Hierarchical state machines for complex behaviors.</li>
-    <li>Context and actions for managing state data and side effects.</li>
-    <li>Guards and conditions for controlling transitions.</li>
-    <li>Parallel states for concurrent behaviors.</li>
-  </ul>
-</section>
-
-<section>
-  <h2>Integrating XState with Three.js</h2>
-  <ul>
-    <li>Create a Three.js scene and renderer.</li>
-    <li>Define game objects and their initial states.</li>
-    <li>Initialize an XState machine to manage the game's overall state.</li>
-  </ul>
-</section>
-
-<section>
-  <h2>Mapping XState States to Game Objects</h2>
-  <ul>
-    <li>Use XState's context to store references to game objects.</li>
-    <li>Define actions to update game object properties and behaviors.</li>
-    <li>Trigger state transitions based on game events or conditions.</li>
-  </ul>
-</section>
-
-<section>
-  <h2>Handling Game Events and Input</h2>
-  <ul>
-    <li>Listen for user input events (e.g., keyboard, mouse, gamepad).</li>
-    <li>
-      Use XState's
-      <code>send</code>
-      function to trigger state transitions based on input.
-    </li>
-    <li>Update game object states and behaviors accordingly.</li>
-  </ul>
-</section>
-
-<section>
-  <h2>Advanced Techniques</h2>
-  <ul>
-    <li>Parallel States</li>
-    <li>History States</li>
-    <li>Delay Transitions</li>
-    <li>Custom Guards and Conditions</li>
-  </ul>
-</section>
-
-<section>
-  <h2>Conclusion</h2>
-
-By leveraging XState, you can create more robust, flexible, and maintainable
-game behaviors. XState's powerful features and intuitive state chart design
-make it an excellent choice for game development using Three.js.
