+# Using Components
+
+Components are features work out of the box that built on top of plugins.
+Each component is a separate module. You can use them by importing them from `@milkdown/kit/component/*`.
+All components can be used just like plugins.
+
+```ts
+import { imageBlock } from "@milkdown/kit/component/image-block";
+import { Editor } from "@milkdown/kit/core";
+
+Editor.make().use(/* some other plugins */).use(imageBlock).create();
+```
+
+Components are designed to be headless, which means they are not opinionated about the UI.
+You can use them to build your own editor UI. Components are built by web components and can be used in any framework.
