export GOOGLE_CLOUD_LOCATION="your-location"
```


### 1. Set Your API Key

```bash
# Option A: Environment variable
export GEMINI_API_KEY="your-api-key-here"

# Option B: Store in config
gemini config set api_key "your-api-key-here"
```

### 2. Analyze Code

```bash
gemini analyze main.py --focus quality
```

### 3. Generate Code

```bash
gemini generate --description "A function that validates email addresses" \
  --requirements "Use regex" "Raise ValueError on invalid input" "Include type hints"
```
