+# Nubank.JS
+Realize operações que você faz no app do nubank pelo node.js Baseado na ([versão python](https://github.com/Astrocoders/nubank-api) que é baseada nessa outra [versão js](https://github.com/Astrocoders/nubank-api))
+
+## Instalação
+Instale por meio do npm:
+
+`npm install nubank.js`
+
+> AVISO: Este não é um modulo oficial de Nu Pagamentos S.A, Este modulo utiliza da [API Publica do Nubank](https://twitter.com/nubank/status/766665014161932288)
+
+> AVISO²: Este projeto ainda está em desenvolvimento e podem ocorrer mudanças na estrutura do codigo
+
+# Exemplo
+
+```typescript
+import NubankJS from 'nubank.js';
+import path from 'path';
+import fs from 'fs';
+
+const USERNAME = process.env.NUBANK_USERNAME || '';
+const PASSWORD = process.env.NUBANK_PASSWORD || '';
+
+const cert = fs.readFileSync(path.join(__dirname, '..', 'cert.p12'));
+const nubankjs = new NubankJS(USERNAME, PASSWORD, cert);
+
+async function run(pixKey: string, value: number) {
+  const { data } = await nubankjs.addPixContact(pixKey);
+
+  const account = data.bankAccount;
+  const transferOutRequest = await nubankjs.transferOutPix(account.id, value);
+
+  const success = transferOutRequest.__typename === 'TransferOutRequestSuccess';
+  let error;
+
+  if (!success) {
+    console.log(transferOutRequest);
+    error = transferOutRequest.errorHandler.description;
+  }
+
+  const result = {
+    success,
+    bank: account.singleBank.number,
+    bankName: account.singleBank.shortName,
+    agency: account.branch,
+    account: account.number,

+    error
+  };
+
+  console.log(result);
+}
+
+run('11999999999', 0.01);
+```
+
+Output:
+```js
+{
+  success: true,
+  bank: null,
+  bankName: 'NEON PAGAMENTOS',
+  agency: '0000',
+  account: '123456',
