## Common Tasks

### Adding a New CVE
```python
# In app.py, find BUILTIN_CVES = [
# Add entry before closing bracket:
{
    "id": "CVE-YYYY-XXXXX",
    "name": "CVE Name",
    "description_en": "...",
    "description_fr": "...",
    "cvss": 8.5,
    "severity": "HIGH",
    "products": "...",
    "year": 2025,
    "published": "2025-02-12"
}
```

### Changing Color Scheme
```python
# In build_interface(), modify:
theme=gr.themes.Soft(primary_hue="red")  # Change "red" to another hue
```

### Adding Search Filter
```python
# In search_cve(), add condition:
if custom_filter_condition:
    results = [r for r in results if condition_met(r)]
```

### Modifying API Timeout
```python
# In search_nvd_api(), change:
response = requests.get(url, headers=headers, timeout=10)  # Change 10
```

---

## Troubleshooting Guide

### Issue: "NVD API not responding"
**Solution**: Tool automatically falls back to built-in database. Check internet connection.

### Issue: "Search returns no results"
**Solution**: Check spelling, try keyword instead of CVE ID, or vice versa.

### Issue: "Language toggle not working"
**Solution**: Refresh page, clear browser cache, check console for errors.

### Issue: "Charts not displaying"
**Solution**: Check Plotly installation, refresh page, try different browser.

### Issue: "App runs slowly"
**Solution**: Check system resources, clear Gradio cache, restart application.
