 A JavaScript library for writing NEAR smart contracts.
 
-## Prerequisites
-
-- node >=14 <16.6.0 || >16.6.0
-- pnpm >=7
+```typescript
+import { NearBindgen, near, call, view } from 'near-sdk-js';
 
-## Quick Start
+@NearBindgen({})
+class HelloNear {
+  greeting: string = 'Hello';
 
-Use [`create-near-app`](https://github.com/near/create-near-app) to quickly get started writing smart contracts in JavaScript on NEAR.
+  @view({}) // This method is read-only and can be called for free
+  get_greeting(): string {
+    return this.greeting;
+  }
 
-    npx create-near-app
+  @call({}) // This method changes the state, for which it cost gas
+  set_greeting({ greeting }: { greeting: string }): void {
+    near.log(`Saving greeting ${greeting}`);
+    this.greeting = greeting;
+  }
+}
+```
