 * TODO Code signing
 * Ideas appreciated :)
 
+## Quick start
+
+> Let suppose, path to your app is **D:\Users\Projects\NW\myapp** (Windows) and **/Users/Projects/NW/myapp** (Linux/MAC OS X).
+
+1. Open terminal ( CMD/BASH ).
+
+2. Navigate to **myapp** directory using **cd D:\Users\Projects\NW\myapp** (Windows) | **cd /Users/Projects/NW/myapp** (Linux/MAC OS X).
+
+3. Check package.json to have at least `name`, `description`, `version`, `scripts` fields. If you don't have package.json, please create it using **npm init** command (provide proper values as it asks) instead of creating it manually (as using **npm init** will add set most of the keys needed). 
+
+Here is the minimal one:
+
+```javascript
+    {
+      "name": "generator",
+      "version": "1.0.0",
+      "description": "An NW based desktop application",
+      "scripts": {
+        "test": "node ./test/test_any.js"
+      }
+    }
+```
+
+4. Now add **build** key and also update **scripts**. 
+
+```javascript
+    {
+      "name": "generator",
+      "version": "1.0.0",
+      "description": "An NW based desktop application",
+      "build": {
+        "nwVersion": "0.35.1"
+      },
+      "scripts": {
+        "test": "node ./test/test_any.js",
+        "dist": "build --tasks win-x86,win-x64,linux-x86,linux-x64,mac-x64 --mirror https://dl.nwjs.io/ .",
+        "start": "run --x86 --mirror https://dl.nwjs.io/ ."
+      }
+    }
+```
+
+5. Install **nwjs-builder-phoenix** locally using **npm install nwjs-builder-phoenix --save-dev**.
+
+```bash
+npm install nwjs-builder-phoenix --save-dev
+```
+
+6. Finally, run **npm run dist**.
+
+```bash
+npm run dist
+```
+
+That's it. 
+
+**Note:** Just wait for packaging process as it depends on speed of Network and number of selected target platforms.

 ## Getting Started
 
 * Make sure your NW.js project has a valid `package.json` (e.g. generated by `npm init`), and have basic fields like `name`, `description` and `version` filled.
