 # XChaCha20-JS
 
-XChaCha20 implementation in a plain JavaScript.
+XChaCha20 implementation in JavaScript (ES6).
 
 This library will auto generate random nonce and append it to the encrypted message.
 
 ## Usage
 
-### 1. Import library
-```html
-<script src="XChaCha20.min.js"></script>
+### 1. Download library
+```bash
+npm i --save @rabbit-company/xchacha20
 ```
 
-### 2. Encryption
+### 2. Import library
+```js
+import XChaCha20 from "@rabbit-company/xchacha20";
+```
+
+### 3. Encryption
 ```js
 XChaCha20.encrypt(message, secretKey);
 ```
 
-### 3. Decryption
+### 4. Decryption
 ```js
 XChaCha20.decrypt(message, secretKey);
 ```
