+name: preset-mini
+description: Minimal preset with essential utilities for UnoCSS
+---
+
+# Preset Mini
+
+The minimal preset with only essential rules and variants. Good starting point for custom presets.
+
+## Installation
+
+```ts
+import { defineConfig, presetMini } from 'unocss'
+
+export default defineConfig({
+  presets: [
+    presetMini(),
+  ],
+})
+```
+
+## What's Included
+
+Subset of `preset-wind3` with essential utilities aligned to CSS properties:
+
+- Basic spacing (margin, padding)
+- Display (flex, grid, block, etc.)
+- Positioning (absolute, relative, fixed)
+- Sizing (width, height)
+- Colors (text, background, border)
+- Typography basics (font-size, font-weight)
+- Borders and border-radius
+- Basic transforms and transitions
+
+## What's NOT Included
+
+Opinionated or complex Tailwind utilities:
+- `container`
+- Complex animations
+- Gradients
+- Advanced typography
+- Prose classes
+
+## Use Cases
+
+1. **Building custom presets** - Start with mini and add only what you need
+2. **Minimal bundle size** - When you only need basic utilities
+3. **Learning** - Understand UnoCSS core without Tailwind complexity
+
+## Dark Mode
+
+Same as preset-wind3:
+
+```ts
+presetMini({
+  dark: 'class' // or 'media'
+})
+```
+
+```html
+<div class="dark:bg-red:10" />
+```
+
+Class-based:
+```css
+.dark .dark\:bg-red\:10 {
+  background-color: rgb(248 113 113 / 0.1);
+}
+```
+
+Media query:
+```css
+@media (prefers-color-scheme: dark) {
+  .dark\:bg-red\:10 {
+    background-color: rgb(248 113 113 / 0.1);
+  }
+}
+```
+
+## CSS @layer Variant
+
+Native CSS layer support:
+
+```html
+<div class="layer-foo:p4" />
+```
+
+```css
+@layer foo {
+  .layer-foo\:p4 {
+    padding: 1rem;
+  }
+}
+```
+
+## Theme Customization
+
+```ts
+presetMini({
+  theme: {
+    colors: {
+      veryCool: '#0000ff',
+      brand: {
+        primary: 'hsl(var(--hue, 217) 78% 51%)',
+      }
+    },
+  }
+})
+```
+
+**Note:** `breakpoints` property is overridden, not merged.
+
+## Options
+
+```ts
+presetMini({
+  // Dark mode: 'class' | 'media' | { light: string, dark: string }
+  dark: 'class',
+  
+  // Generate [group=""] instead of .group for attributify
+  attributifyPseudo: false,
+  
+  // CSS variable prefix (default: 'un-')
+  variablePrefix: 'un-',
+  
+  // Utility prefix
+  prefix: undefined,
+  
+  // Preflight generation: true | false | 'on-demand'
+  preflight: true,
+})
+```
+
+## Building on Mini
+
+Create custom preset extending mini:
+
+```ts
+import { presetMini } from 'unocss'
+import type { Preset } from 'unocss'
+
+export const myPreset: Preset = {
+  name: 'my-preset',
+  presets: [presetMini()],
+  rules: [
+    // Add custom rules
+    ['card', { 'border-radius': '8px', 'box-shadow': '0 2px 8px rgba(0,0,0,0.1)' }],
+  ],
+  shortcuts: {
+    'btn': 'px-4 py-2 rounded bg-blue-500 text-white',
+  },
+}
+```
