HHVM is an open-source virtual machine designed for executing programs written in [Hack](http://hacklang.org) and [PHP](http://php.net). HHVM uses a just-in-time (JIT) compilation approach to achieve superior performance while maintaining the development flexibility that PHP provides.

HHVM supports [Hack](http://hacklang.org), [PHP 5](http://php.net) and the major features of [PHP 7](http://hhvm.com/blog/10859/php-7-support). We are aware of [minor incompatibilities](https://github.com/facebook/hhvm/issues?q=is%3Aopen+is%3Aissue+label%3A%22php5+incompatibility%22), so please [open issues](https://github.com/facebook/hhvm/issues/new) when you find them. HHVM also supports many [extensions](http://docs.hhvm.com/hhvm/extensions/introduction) as well.

HHVM should be used together with a webserver like the built in, easy to deploy [Proxygen](http://docs.hhvm.com/hhvm/basic-usage/proxygen), or a [FastCGI](http://docs.hhvm.com/hhvm/advanced-usage/fastCGI)-based webserver on top of nginx or Apache.

## Installing

If you're new, try our [getting started guide](http://docs.hhvm.com/hhvm/getting-started/getting-started).

You can install a [prebuilt package](http://docs.hhvm.com/hhvm/installation/introduction#prebuilt-packages) or [compile from source](http://docs.hhvm.com/hhvm/installation/building-from-source).

## Running

You can run standalone programs just by passing them to hhvm: `hhvm my_script.php`.

If you want to host a website:
* Install your favorite webserver. [Proxygen](http://docs.hhvm.com/hhvm/basic-usage/proxygen) is built in to HHVM, fast and easy to deploy.
* Install our [package](http://docs.hhvm.com/hhvm/installation/introduction#prebuilt-packages)
* Start your webserver
* Run `sudo /etc/init.d/hhvm start`
* Visit your site at `http://.../index.php`

Our [getting started guide](http://docs.hhvm.com/hhvm/getting-started/getting-started) provides a slightly more detailed introduction as well as links to more information.
