+# Skip Link
+
+Adds a skip navigation link for keyboard accessibility. The link is hidden until focused and allows users to jump directly to the main content.
+
+## Usage
+
+1. Add the Skip Link widget anywhere on your page, preferrably at the top or in a layout.
+2. Configure the **Link Text** and **Main Content ID** properties.
+3. Ensure your main content element has the specified ID, or there's a main tag on the page.
+
+The widget automatically inserts the skip link as the first child of the `#root` element.
+
+## Properties
+
+- **Link Text**: Text displayed for the skip link (default: "Skip to main content").
+- **Main Content ID**: ID of the main content element to focus (optional).
+
+If the target element is not found, the widget will focus the first `<main>` element instead.
+
+## Accessibility
+
+The skip link is positioned absolutely at the top-left of the page, hidden by default with `transform: translateY(-120%)`, and becomes visible when focused via keyboard navigation.
