Chris@0: ## Installation
Chris@0: 
Chris@0: To add Environment as a local, per-project dependency to your project, simply add a dependency on `sebastian/environment` to your project's `composer.json` file. Here is a minimal example of a `composer.json` file that just defines a dependency on Environment 1.0:
Chris@0: 
Chris@0:     {
Chris@0:         "require": {
Chris@0:             "sebastian/environment": "1.0.*"
Chris@0:         }
Chris@0:     }
Chris@0: 
Chris@0: ## Usage
Chris@0: 
Chris@0: ```php
Chris@0: <?php
Chris@0: use SebastianBergmann\Environment\Runtime;
Chris@0: 
Chris@0: $runtime = new Runtime;
Chris@0: 
Chris@0: var_dump($runtime->getNameWithVersion());
Chris@0: var_dump($runtime->getName());
Chris@0: var_dump($runtime->getVersion());
Chris@0: var_dump($runtime->getBinary());
Chris@0: var_dump($runtime->isHHVM());
Chris@0: var_dump($runtime->isPHP());
Chris@0: var_dump($runtime->hasXdebug());
Chris@0: var_dump($runtime->canCollectCodeCoverage());
