+# markdown-rs WASM Bindings
+
+WebAssembly bindings for [markdown-rs](https://github.com/wooorm/markdown-rs).
+
+## Features
+
+- CommonMark compliant
+- GFM support (tables, strikethrough, autolinks, task lists)
+- MDX support (JSX in markdown)
+- Pure ESM module
+- Works in Node.js 16+
+- Single WASM binary (no platform-specific builds)
+
+## Installation
+
+```bash
+pnpm add markdown-rs-wasm
+```
+
+## Usage
+
+```javascript
+import { toHtml, toHtmlWithOptions } from 'markdown-rs-wasm';
+
+// Convert markdown to HTML
+const html = await toHtml('# Hello World');
+
+// With GitHub Flavored Markdown
+const gfmHtml = await toHtmlWithOptions('~strikethrough~', { 
+  gfm: true 
+});
+
+// With MDX support
+const mdxHtml = await toHtmlWithOptions('<Component />', {
+  mdx: true
+});
+```
+
+## API
+
+### `toHtml(markdown: string): Promise<string>`
+
+Converts markdown to HTML using CommonMark.
+
+```javascript
+const html = await toHtml('# Hello World');
+```
+
+### `toHtmlWithOptions(markdown: string, options: Object): Promise<string>`
+
+Converts markdown to HTML with options.
+
+**Options:**
+- `gfm: boolean` - Enable GitHub Flavored Markdown
+- `mdx: boolean` - Enable MDX (JSX in markdown)
+- `frontmatter: boolean` - Enable YAML frontmatter
+- `allowDangerousHtml: boolean` - Allow raw HTML (default: false)
+- `allowDangerousProtocol: boolean` - Allow dangerous protocols (default: false)
+
+## Examples
+
+Run the examples to see the library in action:
+
+```bash
+# Basic example
+pnpm example:basic
+
+# Options example (GFM, MDX, security)
+pnpm example:options
+```
+
+## Testing
+
+```bash
+# Run tests
+pnpm test
+```
+
+## Building
+
+```bash
+# Build WASM module
+pnpm build
+```
+
+## Why WASM?
+
+This implementation uses WebAssembly to provide:
+- Universal compatibility (one binary for all platforms)
+- No native dependencies
+- Reliable performance across environments
