+**A library to generate PDFs in client-side JavaScript.**

+
+## Creating your first document
+
+The easiest way to get started is to drop the CDN hosted library into your page:
+
+```html
+<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.5/jspdf.debug.js" integrity="sha384-CchuzHs077vGtfhGYl9Qtc7Vx64rXBXdIAZIPbItbNyWIRTdG0oYAqki3Ry13Yzu" crossorigin="anonymous"></script>
+```
+
+Integrity-hash generated by https://www.srihash.org/
+
+or can always get latest version via [unpkg](https://unpkg.com/#/)
+
+```html
+<script src="https://unpkg.com/jspdf@latest/dist/jspdf.min.js"></script>
+```
+
+Using yarn:
+
+```bash
+yarn add jspdf
+```
+
+Using npm:
+
+```bash
+npm install jspdf --save
+```
+
+Then you're ready to start making your document:
+
+```javascript
+// Default export is a4 paper, portrait, using milimeters for units
+var doc = new jsPDF()
+
+doc.text('Hello world!', 10, 10)
+doc.save('a4.pdf')
+```
+
+If you want to change the paper size, orientation, or units, you can do:
+
+```javascript
+// Landscape export, 2×4 inches
+var doc = new jsPDF({
+  orientation: 'landscape',
+  unit: 'in',
+  format: [4, 2]
+})
+
+doc.text('Hello world!', 1, 1)
+doc.save('two-by-four.pdf')
+```
+## Angular Configuration:
+
+Add following in angular-cli.json:
+```
+"scripts": [ "../node_modules/jspdf/dist/jspdf.min.js" ]
+```
+and import it in your component:
+```
+import * as jsPDF from 'jspdf'
+```
+
+
+Great! Now give us a Star :)
