+const [serverData, setServerData] = useState([])
+const [filters, setFilters] = useState([])
+const [sorting, setSorting] = useState([])
+
+useEffect(() => {
+  // Fetch from server when filters/sorting change
+  fetchData({ filters, sorting }).then(setServerData)
+}, [filters, sorting])
+
+<Griddy

+/>
+```
+
+## Theming
+
+Griddy uses CSS variables for theming:
+
+```css
+.griddy {
+  --griddy-font-family: inherit;
+  --griddy-font-size: 14px;
+  --griddy-border-color: #e0e0e0;
+  --griddy-header-bg: #f8f9fa;
+  --griddy-header-color: #212529;
+  --griddy-row-bg: #ffffff;
+  --griddy-row-hover-bg: #f1f3f5;
+  --griddy-row-even-bg: #f8f9fa;
+  --griddy-focus-color: #228be6;
+  --griddy-selection-bg: rgba(34, 139, 230, 0.1);
+}
+```
+
+Override in your CSS:
+
+```css
+.my-custom-grid {
+  --griddy-focus-color: #ff6b6b;
+  --griddy-header-bg: #1a1b1e;
+  --griddy-header-color: #ffffff;
+}
+```

+
+## Inline Styling
+
+For dynamic theming:
+
+```tsx
+<Griddy
+  style={{
+    '--griddy-focus-color': brandColor,
+    '--griddy-header-bg': headerBg,
+  } as React.CSSProperties}
+  columns={columns}
+  data={data}
+/>
+```
+
+## Mantine Integration
+
+Griddy integrates seamlessly with Mantine's theme:
+
+```tsx
+import { MantineProvider, useMantineTheme } from '@mantine/core'
+
+function ThemedGrid() {
+  const theme = useMantineTheme()
+
+  return (
+    <Griddy
+      style={{
+        '--griddy-focus-color': theme.colors.blue[6],
+        '--griddy-header-bg': theme.colors.gray[1],
+        '--griddy-border-color': theme.colors.gray[3],
+      } as React.CSSProperties}
+      columns={columns}
+      data={data}
+    />
+  )
+}
+```
+
+## Typography
+
+Customize font family and size:
+
+```css
+.griddy-custom-font {
+  --griddy-font-family: 'Roboto Mono', monospace;
+  --griddy-font-size: 13px;
+}
+```
+
+## Spacing
+
+Adjust cell padding:
+
+```css
+.griddy-compact {
+  --griddy-cell-padding: 0 4px;
+}
+
+.griddy-spacious {
+  --griddy-cell-padding: 0 16px;
+}
+```
+
+## CSS Classes
+
+Griddy exposes these CSS classes for fine-grained control:
+
+| Class | Element |
+|-------|---------|
+| `.griddy` | Root container |
+| `.griddy-container` | Scroll container |
+| `.griddy-thead` | Table header |
+| `.griddy-header-row` | Header row |
+| `.griddy-header-cell` | Header cell |
+| `.griddy-tbody` | Table body (virtual) |
+| `.griddy-row` | Data row |
+| `.griddy-row--focused` | Focused row |
+| `.griddy-row--selected` | Selected row |
+| `.griddy-cell` | Data cell |
+| `.griddy-search-overlay` | Search overlay |
+| `.griddy-pagination` | Pagination controls |
+
+## Advanced Customization
+
+Override specific components:
+
+```css
+/* Custom header styling */
+.griddy .griddy-header-cell {
+  font-weight: 700;
+  text-transform: uppercase;
+  letter-spacing: 0.5px;
+}
+
+/* Custom row hover effect */
+.griddy .griddy-row:hover {
+  box-shadow: 0 2px 4px rgba(0, 0, 0, 0.1);
+  transform: translateY(-1px);
+  transition: all 0.2s ease;
+}
+
+/* Custom focus indicator */
+.griddy .griddy-row--focused {
+  outline: 3px solid var(--griddy-focus-color);
+  outline-offset: -3px;
+  box-shadow: 0 0 0 3px rgba(34, 139, 230, 0.1);
+}
+```
+
+## Responsive Theming
+
+Adjust theme based on screen size:
+
+```css
+@media (max-width: 768px) {
+  .griddy {
+    --griddy-font-size: 12px;
+    --griddy-cell-padding: 0 4px;
+  }
+}
+
+@media (prefers-color-scheme: dark) {
+  .griddy {
+    --griddy-border-color: #373A40;
+    --griddy-header-bg: #25262b;
+    --griddy-header-color: #C1C2C5;
+    --griddy-row-bg: #1A1B1E;
+  }
+}
+```
+
+## Print Styling
+
+Optimize for printing:
+
+```css
+@media print {
+  .griddy {
+    --griddy-border-color: #000000;
+    --griddy-row-even-bg: #f5f5f5;
+    --griddy-font-size: 10pt;
+  }
+
+  .griddy .griddy-pagination,
+  .griddy .griddy-search-overlay {
+    display: none;
+  }
+}
+```
