 # react-render-to-markdown
 
+[![npm version](https://img.shields.io/npm/v/react-render-to-markdown.svg)](https://www.npmjs.com/package/react-render-to-markdown)
+[![license](https://img.shields.io/npm/l/react-render-to-markdown.svg)](https://github.com/SoonIter/react-render-to-markdown/blob/main/LICENSE)
+
+Render React components to Markdown strings — like `renderToString` in `react-dom`, but outputs **Markdown** instead of HTML.
+
+Built on top of `react-reconciler`, this library creates a custom React renderer that traverses the React element tree and produces well-formatted Markdown. It follows **SSR-like behavior**: `useEffect`, `useLayoutEffect`, and `useInsertionEffect` are suppressed (as no-ops), while `useState`, `useMemo`, `useRef`, `useContext`, and other synchronous hooks work as expected.
+
+## Installation
+
+The major version of `react-render-to-markdown` follows the React version. Install the one that matches your project:
+
+```bash
+# React 19
+npm install react-render-to-markdown@19
+
+# React 18
+npm install react-render-to-markdown@18
+```
+
+## Quick Start
+
 ```tsx
 import { renderToMarkdownString } from 'react-render-to-markdown';
 
-const markdown = renderToMarkdownString(<h1>Hello, World!</h1>);
+const markdown = await renderToMarkdownString(<h1>Hello, World!</h1>);
 console.log(markdown); // # Hello, World!
 ```
 
-## Installation
+## Usage
 
-```bash
-npm install react-render-to-markdown
+### Basic HTML Elements
+
+```tsx
+import { renderToMarkdownString } from 'react-render-to-markdown';
+
+await renderToMarkdownString(
+  <div>
+    <strong>foo</strong>
+    <span>bar</span>
+  </div>,
+);
+// Output: '**foo**bar'
 ```
 
+### React Components & Hooks
+
+Synchronous hooks (`useState`, `useMemo`, `useRef`, `useContext`, etc.) work as expected. Client-side effects (`useEffect`, `useLayoutEffect`) are automatically suppressed:
+
+```tsx
+import { createContext, useContext, useMemo, useState } from 'react';
+import { renderToMarkdownString } from 'react-render-to-markdown';
+
+const ThemeContext = createContext('light');
+
+const Article = () => {
+  const [count] = useState(42);
+  const theme = useContext(ThemeContext);
+  const doubled = useMemo(() => count * 2, [count]);
+
+  return (
+    <>
+      <h1>Hello World</h1>
+      <p>Count: {count}, Doubled: {doubled}, Theme: {theme}</p>
+    </>
+  );
+};
+
+await renderToMarkdownString(
+  <ThemeContext.Provider value="dark">
+    <Article />
+  </ThemeContext.Provider>,
+);
+// Output:
+// # Hello World
+//
+// Count: 42, Doubled: 84, Theme: dark
+```
+
+### Code Blocks
+
+Fenced code blocks with language and title support:
+
+```tsx
+await renderToMarkdownString(
+  <pre data-lang="ts" data-title="rspress.config.ts">
+    <code>{'const a = 1;\n'}</code>
+  </pre>,
+);
+// Output:
+// ```ts title=rspress.config.ts
+// const a = 1;
+// ```
+```
+
+For languages that may contain triple backticks (like `markdown`, `mdx`, `md`), four backticks (``````) are automatically used as delimiters.
+
+## Supported Elements
+
+| HTML Element | Markdown Output |
+| --- | --- |
+| `<h1>` – `<h6>` | `#` – `######` headings |
+| `<p>` | Paragraph with trailing newlines |
+| `<strong>`, `<b>` | `**bold**` |
+| `<em>`, `<i>` | `*italic*` |
+| `<code>` | `` `inline code` `` |
+| `<pre>` + `<code>` | Fenced code block (` ``` `) |
+| `<a href="">` | `[text](url)` |
+| `<img>` | `![alt](src)` |
+| `<ul>`, `<ol>`, `<li>` | Unordered / ordered lists |
+| `<blockquote>` | `> blockquote` |
+| `<br>` | Line break |
+| `<hr>` | `---` horizontal rule |
+| `<style>` | Ignored |
+| `<table>`, `<thead>`, `<tbody>`, `<tr>`, `<th>`, `<td>` | GFM table |
+
+Any unrecognized elements (e.g. `<div>`, `<span>`, `<section>`) render their children as-is, acting as transparent wrappers.
+
+## How It Works
+
+1. **Custom React Reconciler** — Uses `react-reconciler` to build a lightweight tree of `MarkdownNode` objects from your React element tree.
+2. **SSR-like Hook Behavior** — Client-side effects (`useEffect`, `useLayoutEffect`, `useInsertionEffect`) are intercepted and turned into no-ops, matching React's Fizz server renderer behavior. This ensures browser-only code (e.g. `document`, `window`) in effects never runs.
+3. **Tree-to-Markdown Serialization** — The `MarkdownNode` tree is serialized to a Markdown string via a recursive `toMarkdown` function.
+
 ## Requirements
 
 ```json
 {
-  "react": "^18.2.0",
+  "react": ">=18.2.0",
   "react-reconciler": "^0.29.0"
 }
 ```
 
+> **Note:** React 18.2 or above is required. The effect-interception mechanism relies on React 18's internal hooks dispatcher (`__SECRET_INTERNALS_DO_NOT_USE_OR_YOU_WILL_BE_FIRED.ReactCurrentDispatcher.current`).
