+## Types
+
+The package includes type definitions for all icons. This is useful if you want to dynamically load icons with the `svelte:component` directive whether you are using TypeScript or JSDoc.
+
+### TypeScript Example
+
+```svelte
+<script lang="ts">
+  import Home from 'lucide-svelte/icons/home';
+  import Library from 'lucide-svelte/icons/library';
+  import Cog from 'lucide-svelte/icons/cog';
+  import type { ComponentType } from 'svelte';
+  import type { Icon } from 'lucide-svelte';
+
+  type MenuItem = {
+    name: string;
+    href: string;
+    icon: ComponentType<Icon>;
+  }
+
+  const menuItems: MenuItem[] = [
+    {
+      name: 'Home',
+      href: '/',
+      icon: Home,
+    },
+    {
+      name: 'Blog',
+      href: '/blog',
+      icon: Library,
+    },
+    {
+      name: 'Projects',
+      href: '/projects',
+      icon: Cog,
+    }
+  ];
+</script>
+
+{#each menuItems as item}
+  <a href={item.href}>
+   <svelte:component this={item.icon} />
+    <span>{item.name}</span>
+  </a>
+{/each}
+```
+
+### JSDoc Example
+
+```svelte
+<script>
+  import Home from 'lucide-svelte/icons/home';
+  import Library from 'lucide-svelte/icons/library';
+  import Cog from 'lucide-svelte/icons/cog';
+
+  /**
+   * @typedef {Object} MenuItem
+   * @property {string} name
+   * @property {string} href
+   * @property {import('svelte').ComponentType<import('lucide-svelte').Icon>} icon
+   */
+
+  /** @type {MenuItem[]} */
+  const menuItems = [
+    {
+      name: 'Home',
+      href: '/',
+      icon: Home,
+    },
+    {
