+
+```tsx
+import { remarkCodeHike, recmaCodeHike } from "codehike/mdx"
+```
+
+### `remarkCodeHike`
+
+A remark plugin that transform codeblocks and inline code into the specified components.
+
+- from annotation
+- you have to provide the components
+
+```tsx
+import { remarkCodeHike, recmaCodeHike } from "codehike/mdx"
+
+/** @type {import('codehike/mdx').CodeHikeConfig} */
+const chConfig = {
+  components: { code: "MyCode", inlineCode: "MyInlineCode" },
+  ignoreCode: (codeblock) => codeblock.lang === "mermaid",
+  syntaxHighlighting: { theme: "github-dark" },
+}
+
+// what you do with the `mdxOptions` depends on what you use to handle mdx
+const mdxOptions = {
+  remarkPlugins: [[remarkCodeHike, chConfig], ...otherRemarkPlugins],
+  recmaPlugins: [[recmaCodeHike, chConfig]],
+}
+```
+
+#### `CodeHikeConfig.components.code`
+
+If you specify a component for `code`, the `remarkCodeHike` plugin will replace code blocks with that component. The language, meta, and value of the code block will be passed inside a `codeblock` prop.

+  )

+
+</Usage>
+
+FAQ
+
+- how to pass the components to the `Content` component?
+- how to syntax highlight the code?
+
+#### `CodeHikeConfig.components.inlineCode`
+
+If you specify a component for `inlineCode`, the `remarkCodeHike` plugin will replace inline code with that component. The value of the inline code will be passed inside a `codeblock` prop.
+
+Code Hike uses a special syntax to define inline code ``_`code`_``. This syntax also allows you to specify the language and meta for inline code ``_py lorem ipsum`print 5`_``, will give you _`{lang: "py", meta: "lorem ipsum", value: "print 5"}`_.
