+A light, cross-platform library for building web-based desktop apps. This package provides a universal client that is compatible with Deno, Node.js, and Bun.
+
+## Compatibility
+
+- ✅ **Node.js** 18+ (fully supported)
+- ✅ **Deno** (original implementation, fully supported)
+- ⚠️ **Bun** (limited support - older versions may have issues)
 
 ## Installation
 
+### Node.js
+```bash
+npm install @justbe/webview
+```
+
+### Deno
 ```typescript
 import { createWebView } from "jsr:@justbe/webview";
 ```
 
+### Bun
+```bash
+bun install @justbe/webview
+```
+
 ## Example
 
 ```typescript
-import { createWebView } from "jsr:@justbe/webview";
+import { createWebView } from "@justbe/webview";
 
 using webview = await createWebView({
   title: "Example",
-  html: "<h1>Hello, World!</h1>",
