 ## 🏁 Getting Started
 
-### Step 1: Install Required Packages
+### Prerequisites
+
+- **Python 3.10 or higher**
+
+- **pip package manager**
+  - Verify with: `pip --version` or `pip3 --version`
+  - Usually comes bundled with Python 3.4+ installers from python.org
+  - If pip is missing, install using one of these methods:
+    ```bash
+    # Method 1 - Use Python's built-in module
+    python -m ensurepip --upgrade
+
+    # Method 2 - Download and run the official installer
+    curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
+    python get-pip.py
+    ```
+
+### Step 1: Create Virtual Environment
+
+```bash
+# Create virtual environment
+python -m venv venv
+
+# Activate virtual environment
+# On macOS/Linux:
+source venv/bin/activate
+# On Windows:
+venv\Scripts\activate
+```
+
+### Step 2: Install Required Packages
 
 ```bash
+# Install Strands core packages (required for all examples)
 pip install strands-agents
 pip install strands-agents-tools
 ```
 
-### Step 2: Setup Model Provider
+> **Additional Dependencies:** Individual examples throughout this repository may require extra packages. When working with a specific example, check for its `requirements.txt` file:
+> ```bash
+> # Navigate to the example folder you want to run
+> cd [example-directory]
+>
+> # Install dependencies if requirements.txt exists
+> pip install -r requirements.txt
+> ```
