+# How to contribute
+
+Everybody should be able to help. Here's how you can make this project more
+awesome:
+
+1. [Fork it](https://github.com/memio/pretty-printer/fork_select)
+2. improve it
+3. submit a [pull request](https://help.github.com/articles/creating-a-pull-request)
+
+Your work will then be reviewed as soon as possible (suggestions about some
+changes, improvements or alternatives may be given).
+
+Here's some tips to make you the best contributor ever:
+
+* [Standard code](#standard-code)
+* [Specifications](#specifications)
+* [Keeping your fork up-to-date](#keeping-your-fork-up-to-date)
+
+## Standard code
+
+Use [PHP CS fixer](http://cs.sensiolabs.org/) to make your code compliant with
+Memio PrettyPrinter's coding standards:
+
+    ./vendor/bin/php-cs-fixer fix --config=sf23 .
+
+## Specifications
+
+Memio PrettyPrinter drives its development using [phpspec](http://www.phpspec.net/):
+
+    # Generate the specification class:
+    phpspec describe 'Memio\Memio\MyNewClass'
+
+    # Customize the specification class:
+    $EDITOR tests/spec/Memio/pretty-printer/MyNewClass.php
+
+    # Generate the specified class:
+    phpspec run
+
+    # Customize the class:
+    $EDITOR src/Memio/pretty-printer/MyNewClass.php
+
+    phpspec run # Should be green!
+
+## Keeping your fork up-to-date
+
+To keep your fork up-to-date, you should track the upstream (original) one
+using the following command:
+
+    git remote add upstream https://github.com/memio/pretty-printer.git
+
+Then get the upstream changes:
+
+    git checkout master
+    git pull --rebase origin master
+    git pull --rebase upstream master
+    git checkout <your-branch>
+    git rebase master
+
+Finally, publish your changes:
+
+    git push -f origin <your-branch>
+
+Your pull request will be automatically updated.

+# Memio's PrettyPrinter [![SensioLabsInsight](https://insight.sensiolabs.com/projects/a2b24423-9840-45ab-a011-598aa3ba26bf/mini.png)](https://insight.sensiolabs.com/projects/a2b24423-9840-45ab-a011-598aa3ba26bf) [![Travis CI](https://travis-ci.org/memio/pretty-printer.png)](https://travis-ci.org/memio/pretty-printer)
+
+`PrettyPrinter` is a code generator (printer) that takes a Model and calls the
+appropriate `TemplateEngine` to actually generate the corresponding code,
+using highly opinionated coding standards (pretty).
+
+`PrettyPrinter` returns a string that can be saved in a file, dislpayed on a
+console output or displayed in a web page. Possibilities are endless!
+
+> **Note**: This package is part of [Memio](http://memio.github.io/memio).
+> Have a look at [the main repository](http://github.com/memio/memio).
+
+## Installation
+
+Install it using [Composer](https://getcomposer.org/download):
+
+    composer require memio/pretty-printer:~1.0@rc
+
+## Example
+
+We're going to generate a class with a constructor and two attributes:
+
+```php
+<?php
+
+require __DIR__.'/vendor/autoload.php';
+
+use Memio\Memio\PrettyPrinter;
+use Memio\Model\File;
+use Memio\Model\Object;
+use Memio\Model\Property;
+use Memio\Model\Method;
+use Memio\Model\Argument;
+
+// Initialize the code generator
+$loader = new \Twig_Loader_Filesystem(__DIR__.'/vendor/memio/pretty-printer/templates');
+$twig = new \Twig_Environment($loader);
+$prettyPrinter = new PrettyPrinter($twig);
+
+// Describe the code you want to generate using "Models"
+$myService = File::make('src/Vendor/Project/MyService.php')
+    ->setStructure(
+        Object::make('Vendor\Project\MyService')
+            ->addProperty(new Property('createdAt'))
+            ->addProperty(new Property('filename'))
+            ->addMethod(
+                Method::make('__construct')
+                    ->addArgument(new Argument('DateTime', 'createdAt'))
+                    ->addArgument(new Argument('string', 'filename'))
+            )
+    )
+;
+
+// Generate the code and display in the console
+echo $prettyPrinter->generateCode($myService);
+
+// Or display it in a browser
+// echo '<pre>'.htmlspecialchars($prettyPrinter->generateCode($myService)).'</pre>';
+```
+
+With this simple example, we get the following output:
+
+```
+<?php
+
+namespace Vendor\Project;
+
+class MyService
+{
+    private $createdAt;
+
+    private $filename;
+
+    public function __construct(DateTime $createdAt, $filename)
+    {
+    }
+}
+```
+
+Have a look at [the main respository](http://github.com/memio/memio) to discover the full power of Memio.
+
+## Want to know more?
+
+Memio uses [phpspec](http://phpspec.net/), which means the tests also provide the documentation.
+Not convinced? Then clone this repository and run the following commands:
+
+    composer install
+    ./vendor/bin/phpspec run -n -f pretty
+
+You can see the current and past versions using one of the following:
+
+* the `git tag` command
+* the [releases page on Github](https://github.com/memio/memio/releases)
+* the file listing the [changes between versions](CHANGELOG.md)
+
+And finally some meta documentation:
+
+* [copyright and MIT license](LICENSE)
+* [versioning and branching models](VERSIONING.md)
+* [contribution instructions](CONTRIBUTING.md)

+# Versioning and branching models
+
+This file explains the versioning and branching models of this project.
+
+## Versioning
+
+The versioning is inspired by [Semantic Versioning](http://semver.org/):
+
+> Given a version number MAJOR.MINOR.PATCH, increment the:
+>
+> 1. MAJOR version when you make incompatible API changes
+> 2. MINOR version when you add functionality in a backwards-compatible manner
+> 3. PATCH version when you make backwards-compatible bug fixes
+
+### Public API
+
+Classes and methods marked with the `@api` tag are considered to be the public
+API of this project.
+
+## Branching Model
+
+The branching is inspired by [@jbenet](https://github.com/jbenet)
+[simple git branching model](https://gist.github.com/jbenet/ee6c9ac48068889b0912):
+
+> 1. `master` must always be deployable.
+> 2. **all changes** are made through feature branches (pull-request + merge)
+> 3. rebase to avoid/resolve conflicts; merge in to `master`
