**Get your API key**:

Then set it up:

```
# Option 1: Create .env file (recommended)
cp .env.example .env
# Edit .env and replace 'sk-your-openai-api-key-here' with your actual key
nano .env  # or use your preferred editor

# Option 2: Export directly (temporary, for current session only)
export OPENAI_API_KEY=sk-your-actual-key-here
