+# UnoCSS Theme
+
+UnoCSS supports theming similar to Tailwind CSS / Windi CSS. The `theme` property is deep-merged with the default theme.
+
+## Basic Usage
+
+```ts
+theme: {
+  colors: {
+    veryCool: '#0000ff', // class="text-very-cool"
+    brand: {
+      primary: 'hsl(var(--hue, 217) 78% 51%)', // class="bg-brand-primary"
+      DEFAULT: '#942192' // class="bg-brand"
+    },
+  },
+}
+```
+
+## Using Theme in Rules
+
+Access theme values in dynamic rules:
+
+```ts
+rules: [
+  [/^text-(.*)$/, ([, c], { theme }) => {
+    if (theme.colors[c])
+      return { color: theme.colors[c] }
+  }],
+]
+```
+
+## Using Theme in Variants
+
+```ts
+variants: [
+  {
+    name: 'variant-name',
+    match(matcher, { theme }) {
+      // Access theme.breakpoints, theme.colors, etc.
+    },
+  },
+]
+```
+
+## Using Theme in Shortcuts
+
+```ts
+shortcuts: [
+  [/^badge-(.*)$/, ([, c], { theme }) => {
+    if (Object.keys(theme.colors).includes(c))
+      return `bg-${c}4:10 text-${c}5 rounded`
+  }],
+]
+```
+
+## Breakpoints
+
+**Warning:** Custom `breakpoints` object **overrides** the default, not merges.
+
+```ts
+theme: {
+  breakpoints: {
+    sm: '320px',
+    md: '640px',
+  },
+}
+```
+
+Only `sm:` and `md:` variants will be available.
+
+### Inherit Default Breakpoints
+
+Use `extendTheme` to merge with defaults:
+
+```ts
+extendTheme: (theme) => {
+  return {
+    ...theme,
+    breakpoints: {
+      ...theme.breakpoints,
+      sm: '320px',
+      md: '640px',
+    },
+  }
+}
+```
+
+**Note:** `verticalBreakpoints` works the same for vertical layout.
+
+### Breakpoint Sorting
+
+Breakpoints are sorted by size. Use consistent units to avoid errors:
+
+```ts
+theme: {
+  breakpoints: {
+    sm: '320px',
+    // Don't mix units - convert rem to px
+    // md: '40rem', // Bad
+    md: `${40 * 16}px`, // Good
+    lg: '960px',
+  },
+}
+```
+
+## ExtendTheme
+
+`extendTheme` lets you modify the merged theme object:
+
+### Mutate Theme
+
+```ts
+extendTheme: (theme) => {
+  theme.colors.veryCool = '#0000ff'
+  theme.colors.brand = {
+    primary: 'hsl(var(--hue, 217) 78% 51%)',
+  }
+}
+```
+
+### Replace Theme
+
+Return a new object to completely replace:
+
+```ts
+extendTheme: (theme) => {
+  return {
+    ...theme,
+    colors: {
+      ...theme.colors,
+      veryCool: '#0000ff',
+    },
+  }
+}
+```
+
+## Theme Differences in Presets
+
+### preset-wind3 vs preset-wind4
+
+| preset-wind3 | preset-wind4 |
+|--------------|--------------|
+| `fontFamily` | `font` |
+| `fontSize` | `text.fontSize` |
+| `lineHeight` | `text.lineHeight` or `leading` |
+| `letterSpacing` | `text.letterSpacing` or `tracking` |
+| `borderRadius` | `radius` |
+| `easing` | `ease` |
+| `breakpoints` | `breakpoint` |
+| `boxShadow` | `shadow` |
+| `transitionProperty` | `property` |
+
+## Common Theme Keys
+
+- `colors` - Color palette
+- `breakpoints` - Responsive breakpoints
+- `fontFamily` - Font stacks
+- `fontSize` - Text sizes
+- `spacing` - Spacing scale
+- `borderRadius` - Border radius values
+- `boxShadow` - Shadow definitions
+- `animation` - Animation keyframes and timing
