# What is Flight?
Flight is a fast, simple, extensible framework for PHP. Flight enables you to
quickly and easily build RESTful web applications.
# Basic Usage
```php
// if installed with composer
require 'vendor/autoload.php';
// or if installed manually by zip file
// require 'flight/Flight.php';
Flight::route('/', function() {
echo 'hello world!';
});
Flight::start();
```
## Skeleton App
You can also install a skeleton app. Go to [flightphp/skeleton ](https://github.com/flightphp/skeleton ) for instructions on how to get started!
# Documentation
We have our own documentation website that is built with Flight (naturally). Learn more about the framework at [docs.flightphp.com ](https://docs.flightphp.com ).
# Community
Chat with us on Matrix IRC [#flight-php-framework:matrix.org ](https://matrix.to/#/#flight-php-framework:matrix.org )
# Requirements
Flight requires `PHP 7.4` or greater.
**Note:** PHP 7.4 is supported because at the current time of writing (2024) PHP 7.4 is the default version for some LTS Linux distributions. Forcing a move to PHP >8 would cause a lot of heartburn for those users. The framework also supports PHP >8.
# License
Flight is released under the [MIT ](http://docs.flightphp.com/license ) license.
