+### 1️⃣ Create and activate a virtual environment
+
+```bash
+# Create a virtual environment named "py_env_lunar_lander"
+python3 -m venv py_env_lunar_lander
+
+# Activate the virtual environment
+# On macOS/Linux:
+source py_env_lunar_lander/bin/activate

+pip install stable-baselines3==2.0.0a5 gymnasium[box2d]
+```
+
+## Usage (with Stable-baselines3)
+After installing dependencies, run the following script to load the trained model, run an episode, and generate a video.
 ```python
 import gymnasium as gym
