# Getting started
## Software requirements
The following software is required to develop using PhpSpreadsheet:
- PHP version 5.6 or newer
- PHP extension php\_zip enabled
- PHP extension php\_xml enabled
- PHP extension php\_gd2 enabled (if not compiled in)
### PHP version support
Support for PHP versions will only be maintained for a period of six months beyond the end-of-life of that PHP version
## Installation
Use [composer](https://getcomposer.org) to install PhpSpreadsheet into your project:
```sh
composer require phpoffice/phpspreadsheet
```
## Hello World
This would be the simplest way to write a spreadsheet:
```php
<?php
require 'vendor/autoload.php';
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();
$sheet->setCellValue('A1', 'Hello World !');
$writer = new Xlsx($spreadsheet);
$writer->save('hello world.xlsx');
```
## Learn by example
A good way to get started is to run some of the samples. Serve the samples via
PHP built-in webserver:
```sh
php -S localhost:8000 -t vendor/phpoffice/phpspreadsheet/samples
```
Then point your browser to:
> http://localhost:8000/
The samples may also be run directly from the command line, for example:
```sh
php vendor/phpoffice/phpspreadsheet/samples/Basic/01_Simple.php
```
