+# ComfyUI Custom Icons Guide
+
+This guide explains how to add and use custom SVG icons in the ComfyUI frontend.
+
+## Overview
+
+ComfyUI uses a hybrid icon system that supports:
+- **PrimeIcons** - Legacy icon library (CSS classes like `pi pi-plus`)
+- **Iconify** - Modern icon system with 200,000+ icons
+- **Custom Icons** - Your own SVG icons
+
+Custom icons are powered by [unplugin-icons](https://github.com/unplugin/unplugin-icons) and integrate seamlessly with Vue's component system.
+
+## Quick Start
+
+### 1. Add Your SVG Icon
+
+Place your SVG file in the `custom/` directory:
+```
+src/assets/icons/custom/
+└── your-icon.svg
+```
+
+### 2. Use in Components
+
+```vue
+<template>
+  <!-- Use as a Vue component -->
+  <i-comfy:your-icon />
+  
+  <!-- In a PrimeVue button -->
+  <Button>
+    <template #icon>
+      <i-comfy:your-icon />
+    </template>
+  </Button>
+</template>
+```
+
+## SVG Requirements
+
+### File Naming
+- Use kebab-case: `workflow-icon.svg`, `node-tree.svg`
+- Avoid special characters and spaces
+- The filename becomes the icon name
+
+### SVG Format
+```xml
+<svg viewBox="0 0 24 24" xmlns="http://www.w3.org/2000/svg">
+  <path d="..." />
+</svg>
+```
+
+**Important:**
+- Use `viewBox` for proper scaling (24x24 is standard)
+- Don't include `width` or `height` attributes
+- Use `currentColor` for theme-aware icons
+- Keep SVGs optimized and simple
+
+### Color Theming
+
+For icons that adapt to the current theme, use `currentColor`:
+
+```xml
+<!-- ✅ Good: Uses currentColor -->
+<svg viewBox="0 0 24 24">
+  <path stroke="currentColor" fill="none" d="..." />
+</svg>
+
+<!-- ❌ Bad: Hardcoded colors -->
+<svg viewBox="0 0 24 24">
+  <path stroke="white" fill="black" d="..." />
+</svg>
+```
+
+## Usage Examples
+
+### Basic Icon
+```vue
+<i-comfy:workflow />
+```
+
+### With Classes
+```vue
+<i-comfy:workflow class="text-2xl text-blue-500" />
+```
+
+### In Buttons
+```vue
+<Button severity="secondary" text>
+  <template #icon>
+    <i-comfy:workflow />
+  </template>
+</Button>
+```
+
+### Conditional Icons
+```vue
+<template #icon>
+  <i-comfy:workflow v-if="isWorkflow" />
+  <i-comfy:node v-else />
+</template>
+```
+
+## Technical Details
+
+### How It Works
+
+1. **unplugin-icons** automatically discovers SVG files in `custom/`
+2. During build, SVGs are converted to Vue components
+3. Components are tree-shaken - only used icons are bundled
+4. The `i-` prefix and `comfy:` namespace identify custom icons
+
+### Configuration
+
+The icon system is configured in `vite.config.mts`:
+
+```typescript
+Icons({
+  compiler: 'vue3',
+  customCollections: {
+    'comfy': FileSystemIconLoader('src/assets/icons/custom'),
+  }
+})
+```
+
+### TypeScript Support
+
+Icons are automatically typed. If TypeScript doesn't recognize a new icon:
+1. Restart your dev server
+2. Check that the SVG file is valid
+3. Ensure the filename follows kebab-case convention
+
+## Troubleshooting
+
+### Icon Not Showing
+1. **Check filename**: Must be kebab-case without special characters
+2. **Restart dev server**: Required after adding new icons
+3. **Verify SVG**: Ensure it's valid SVG syntax
+4. **Check console**: Look for Vue component resolution errors
+
+### Icon Wrong Color
+- Replace hardcoded colors with `currentColor`
+- Use `stroke="currentColor"` for outlines
+- Use `fill="currentColor"` for filled shapes
+
+### Icon Wrong Size
+- Remove `width` and `height` from SVG
+- Ensure `viewBox` is present
+- Use CSS classes for sizing: `class="w-6 h-6"`
+
+## Best Practices
+
+1. **Optimize SVGs**: Use tools like [SVGO](https://jakearchibald.github.io/svgomg/) to minimize file size
+2. **Consistent viewBox**: Stick to 24x24 or 16x16 for consistency
+3. **Semantic names**: Use descriptive names like `workflow-duplicate` not `icon1`
+4. **Theme support**: Always use `currentColor` for adaptable icons
+5. **Test both themes**: Verify icons look good in light and dark modes
+
+## Migration from PrimeIcons
+
+When replacing a PrimeIcon with a custom icon:
+
+```vue
+<!-- Before: PrimeIcon -->
+<Button icon="pi pi-box" />
+
+<!-- After: Custom icon -->
+<Button>
+  <template #icon>
+    <i-comfy:workflow />
+  </template>
+</Button>
+```
+
+## Adding Icon Collections
+
+To add an entire icon set from npm:
+
+1. Install the icon package
+2. Configure in `vite.config.mts`
+3. Use with the appropriate prefix
+
+See the [unplugin-icons documentation](https://github.com/unplugin/unplugin-icons) for details.
