# Azure Icons Stencil for Draw.io

This directory contains stencil files for using Azure Architecture Icons in Draw.io (diagrams.net).

## Using the Stencil

### Method 1: Import Icons Directly

1. Open [Draw.io](https://app.diagrams.net/)
2. Click "More Shapes" (bottom left)
3. Click "+" to add a new library
4. Select "From Device"
5. Navigate to `assets/azure-icons/svg/`
6. Select the icons you want to use
7. Click "Create"

### Method 2: Use Icon Mapping

1. Open Draw.io
2. File → Open Library → From → Device
3. Select `azure-icons-library.json`
4. Icons will appear in the left panel

### Method 3: Manual Import

1. Open Draw.io
2. Click "Insert" → "Image"
3. Select "From Device"
4. Navigate to `assets/azure-icons/svg/`
5. Select the icon file
6. Click "Open"

## Icon Categories

Icons are organized by category:
- Compute (AKS, VMs, Containers)
- Networking (VNet, Gateway, Load Balancer)
- Storage (Storage Account, Blob, File Share)
- Security (Key Vault, AAD, Firewall)
- Management (Resource Groups, Monitor, Log Analytics)

## Best Practices

1. Use SVG icons for scalability
2. Maintain consistent icon size
3. Use official Azure icons only
4. Follow Azure Architecture Center guidelines
5. Label all components clearly
