-Datatables is a package that uses [Doctrine](http://docs.doctrine-project.org/projects/doctrine-orm/en/latest) or [Eloquent](https://laravel.com/docs/master/eloquent) to generate a [server-side AJAX result](https://datatables.net/examples/data_sources/server_side.html) to a [Datatable](https://datatables.net/) instance with little to no configuration.
-
-## Installation
-
-Install `Datatables` via [Composer](https://getcomposer.org/):
-
-``` bash
-$ composer require rougin/datatables
-```
-
-## Basic Usage
-
-### Doctrine
-
-``` php
-use Rougin\Datatables\Legacy\DoctrineBuilder;
-
-$entity = 'Acme\Doctrine\Models\User';
-
-$builder = new DoctrineBuilder($manager, $entity, $_GET);
-
-header('Content-Type: application/json');
-
-echo json_encode($builder->make());
-```
-
-**NOTE**: `$manager` must return an instance of `Doctrine\ORM\EntityManager`. See [DoctrineBuilderTest::setUp](https://github.com/rougin/datatables/blob/master/tests/DoctrineBuilderTest.php#L26) for the sample implementation.
-
-### Eloquent
-
-``` php

-
-$model = 'Acme\Eloquent\Models\UserModel';
-
-$builder = new EloquentBuilder($model, $_GET);
