-## Accessibility
-
-The Slider component follows WAI-ARIA guidelines for the [Slider Pattern](https://www.w3.org/WAI/ARIA/apg/patterns/slider/).
-
-### ARIA Attributes
-
-The component handles the following ARIA attributes:
-
-- `aria-label`: Provides an accessible name for the slider
-- `aria-valuetext`: Provides a human-readable text alternative for the current value
-- `aria-valuemin`: Set automatically based on the `min` prop
-- `aria-valuemax`: Set automatically based on the `max` prop
-- `aria-valuenow`: Updated automatically as the value changes
-
-### Example with Custom ARIA Labels
-
-```tsx
-<div style={{ width: "400px" }}>
-  <Slider
-    variant="range"
-    label={["Start Date", "End Date"]}
-    defaultValue={[20, 80]}
-    aria-label="Date range selector"
-    aria-valuetext="From January 20 to January 80"
-    onChange={value => console.log(value)}
-  />
-</div>
-```
-
-### Screen Reader Considerations
-
-- Each thumb in a range slider has its own accessible label
-- Values are announced as they change
-- The component supports both mouse and keyboard interactions
-- Labels are properly associated with their respective thumbs
