+## Getting Started
+
+Visit [https://alephjs.org/docs/get-started](https://alephjs.org/docs/get-started) to get started with Aleph.js.
+
+
+## Description
+
+Aleph.js (or **Aleph** or **א** or **阿莱夫**, **ˈɑːlɛf**) is a fullstack framework in [Deno](https://deno.land/), inspired by [Next.js](https://nextjs.org/). The name is taken from the book **The Aleph** by [Jorge Luis Borges](http://phinnweb.org/links/literature/borges/aleph.html).
+
+Different with Next.js, Aleph.js doesn't need webpack or other bundler since it uses the [ES Moudule](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Modules) syntax during development. Every module only needs to be compiled once, and then cached on the disk. When a module changes, Aleph.js just needs to re-compile that single module. There is no time wasted re-bundling everytime a change is made. This, along with Hot Module Replacement (HMR) and Fast Refresh, leads to instant updates in the browser.
+
+Aleph.js uses modern tools to build your app. It transpiles code using [swc](https://swc.rs/) in [WASM](https://webassembly.org/) with high performance, and bundles modules with [esbuild](https://github.com/evanw/esbuild) at build time extremely fast.
+
+Aleph.js works in Deno, a simple, modern and secure runtime for JavaScript and TypeScript. All dependencies are imported using URLs, and managed by Deno cache system. No package.json and node_modules directory needed.
+
+```ts
+import React from 'https://esm.sh/react'
+import Logo from '../components/logo.tsx'
+
+export default function Home() {
+  return (
+    <div>
+      <Logo />
+      <h1>Hello World!</h1>
+    </div>
+  )
+}
+```
+
