+hack2php is a project which aims to implement a compiler to translate Hack files to PHP 7 files.  
 This ability becomes useful when you have no control over the environment in which your code is supposed to run, but you still want to write your code in Hack.
-An example might be the development of WordPress plugins or themes.

+## Getting started
+
+Add this to your _composer.json_:
+
+```json
+    "repositories": [
+        {
+            "type": "vcs",
+            "url": "https://github.com/codeneric/hack2php"
+        }
+    ],
+```
+
+Then run `hhvm composer.phar require --dev codeneric\hack2php dev-master`
+
+### Compile a Hack file to PHP
+
+First make sure you have a directory for the new php files (`mkdir <output-target>`).
+
+Compile: `vendor/bin/hack2php <src/file.hh> > <output-target/file.php>`
 
-# Getting started
-Clone this repository and run `hhvm composer.phar install`
+To validate the php code you can run `php -l <output-target/file.php>`
 
-Compile a Hack file to PHP: `./bin/hack2php <hack-file>` 
+## Tests
 
-# Tests
-There is only one test (HackToPhpTest). It reads each Hack file from the example-files directory, compiles it to PHP and checks the PHP syntax for errors. If no error were found, the test succeeds. Otherwise it fails. 
-To add a test, simply create a new Hack file in example-files. 
-Run the test: ` hhvm vendor/bin/phpunit`

-# Contributing
-If you find an issue you can help to fix it. Please add a Hack file which is not compiled correctly in the example-files folder and create a PR. 
-Or you can fix the issue directly :)
-But please add an example Hack file to the example-files folder nonetheless.
