# Installation
## System Requirements
You need **PHP >= 5.5.0** and the `mbstring` extension to use `Csv` but the latest stable version of PHP is recommended.
## Composer
`Csv` is available on [Packagist](https://packagist.org/packages/league/csv) and can be installed using [Composer](https://getcomposer.org/):
```bash
composer require league/csv:^8.0
```
## Going Solo
You can also use `League\Csv` without using Composer by downloading the library on Github.
- Visit [the releases page](https://github.com/thephpleague/csv/releases);
- Select the version you want
- click the Source Code download link in your preferred compress format;
The library is compatible with any [PSR-4](http://www.php-fig.org/psr/psr-4/) compatible autoloader.
Also, `League\Csv` comes bundle with its own autoloader script `autoload.php` located in the root directory.
```php
use League\Csv\Reader;
use League\Csv\Writer;
require '/path/to/league/csv/autoload.php';
//your script starts here
```
where `path/to/league/csv` represents the path where the library was extracted.
