+# PHP Make
+
+Pake is a simple task runner.
+
+Pake is a Make-like program implemented in PHP.  
+Tasks and dependencies are specified in standard PHP syntax.
+
+Pakefiles (pake's version of Makefiles) are completely defined in standard PHP syntax.
+
+## Installation
+
+These commands requires you to have Composer installed globally.
+Open a command console, enter your project directory and execute the following 
+commands to download the latest stable version:
+
+```sh
+composer require --dev roukmoute/pake
+```
+
+## Usage
+
+### Example
+
+First, you must write a `Pakefile` file which contains the build rules.  
+Here's a simple example:
+
+```php
+<?php
+
+use PhpCsFixer\Console\Application;
+use Symfony\Component\Console\Input\ArrayInput;
+
+task(
+    'default',
+    function () {
+        return ['fix', 'example'];
+    }
+);
+
+desc('PHP Coding Standards Fixer');
+task(
+    'fix',
+    function () {
+        $application = new Application();
+        $application->setAutoExit(false);
+        $application->run(new ArrayInput(['fix']));
+    }
+);
+```
+
+This Pakefile has two tasks:
+
+- A task named `fix`, which – upon invocation – will fix your code to follow 
+standards in PHP:
+```sh
+▶ php ./vendor/bin/pake fix
+```
+- A task named `default`. This task does nothing by itself, but it has exactly 
+one dependency, namely the `fix` task.  
+Invoking the `default` task will cause Pake to invoke the `fix` task as well.
+
+Running the `pake` command without any options will cause it to run the 
+`default` task in the Pakefile:
+
+```sh
+▶ php ./vendor/bin/pake
+Loaded config default from ".php_cs.dist".
+Using cache file ".php_cs.cache".
+....unit fix output here...
+```
+
+Type `pake --help` for all available options.
