+
+## Installation
+
+To install the project and run the tests, you need to clone it first:
+
+```sh
+$ git clone git://github.com/doctrine/instantiator.git
+```
+
+You will then need to run a composer installation:
+
+```sh
+$ cd Instantiator
+$ curl -s https://getcomposer.org/installer | php
+$ php composer.phar update
+```
+
+## Testing
+
+The PHPUnit version to be used is the one installed as a dev- dependency via composer:
+
+```sh
+$ ./vendor/bin/phpunit
+```
+
+Accepted coverage for new contributions is 80%. Any contribution not satisfying this requirement 
+won't be merged.

+
+## Installation
+
+The suggested installation method is via [composer](https://getcomposer.org/):
+
+```sh
+php composer.phar require "doctrine/instantiator:~1.0.3"
+```
+
+## Usage
+
+The instantiator is able to create new instances of any class without using the constructor or any API of the class
+itself:
+
+```php
+$instantiator = new \Doctrine\Instantiator\Instantiator();
+
+$instance = $instantiator->instantiate(\My\ClassName\Here::class);
+```
+
+## Contributing
+
+Please read the [CONTRIBUTING.md](CONTRIBUTING.md) contents if you wish to help out!
+
+## Credits
+
+This library was migrated from [ocramius/instantiator](https://github.com/Ocramius/Instantiator), which
+has been donated to the doctrine organization, and which is now deprecated in favour of this package.

+Introduction
+============
+
+This library provides a way of avoiding usage of constructors when instantiating PHP classes.
+
+Installation
+============
+
+The suggested installation method is via `composer`_:
+
+.. code-block:: console
+
+   $ composer require doctrine/instantiator
+
+Usage
+=====
+
+The instantiator is able to create new instances of any class without
+using the constructor or any API of the class itself:
+
+.. code-block:: php
+
+    <?php
+
+    use Doctrine\Instantiator\Instantiator;
+    use App\Entities\User;
+
+    $instantiator = new Instantiator();
+
+    $user = $instantiator->instantiate(User::class);
+
+Contributing
+============
+
+-  Follow the `Doctrine Coding Standard`_
+-  The project will follow strict `object calisthenics`_
+-  Any contribution must provide tests for additional introduced
+   conditions
+-  Any un-confirmed issue needs a failing test case before being
+   accepted
+-  Pull requests must be sent from a new hotfix/feature branch, not from
+   ``master``.
+
+Testing
+=======
+
+The PHPUnit version to be used is the one installed as a dev- dependency
+via composer:
+
+.. code-block:: console
+
+   $ ./vendor/bin/phpunit
+
+Accepted coverage for new contributions is 80%. Any contribution not
+satisfying this requirement won’t be merged.
+
+Credits
+=======
+
+This library was migrated from `ocramius/instantiator`_, which has been
+donated to the doctrine organization, and which is now deprecated in
+favour of this package.
