## 📖 Documentation
### Quick Start Guide
PptxGenJS PowerPoint presentations are created via JavaScript by following 4 basic steps:
#### Angular/React, ES6, TypeScript
```typescript
import pptxgen from "pptxgenjs";
// 1. Create a new Presentation
let pres = new pptxgen();
// 2. Add a Slide
let slide = pres.addSlide();
// 3. Add one or more objects (Tables, Shapes, Images, Text and Media) to the Slide
let textboxText = "Hello World from PptxGenJS!";
let textboxOpts = { x: 1, y: 1, color: "363636" };
slide.addText(textboxText, textboxOpts);
// 4. Save the Presentation
pres.writeFile();
```
#### Script/Web Browser
```javascript
// 1. Create a new Presentation
let pres = new PptxGenJS();
// 2. Add a Slide
let slide = pres.addSlide();
// 3. Add one or more objects (Tables, Shapes, Images, Text and Media) to the Slide
let textboxText = "Hello World from PptxGenJS!";
let textboxOpts = { x: 1, y: 1, color: "363636" };
slide.addText(textboxText, textboxOpts);
// 4. Save the Presentation
pres.writeFile();
```
That's really all there is to it!
