+Package ini dibuat untuk memudahkan proses mendapatkan data dengan menggunakan filter, sort, atau select berdasarkan request data yang dikirimkan. Package ini secara khusus diciptakan untuk memenuhi kebutuhan integrasi antara Framework [Laravel](https://laravel.com) dengan [Data Grid by DevExpress](https://js.devexpress.com/Overview/DataGrid/). Namun secara umum package ini dapat digunakan meskipun tanpa menggunakan [Data Grid by DevExpress](https://js.devexpress.com/Overview/DataGrid/). 
+
+Package `QueryAdapter` ini juga mengimplementasikan Laravel default Eloquent builder. Ini membuat anda dapat menggunakan fungsi-fungsi yang ada di Eloquent dapat anda gunakan juga menggunakan package ini.
+  
+
+## Penggunaan Dasar
+
+Package ini dapat digunakan dengan beberapa opsi, bisa menggunakan Facade `QueryBuilder` atau langsung menggunakan Class `DxAdapter`. 
+
+### Jika menggunakan model langsung
+
+```php
+use GhoniJee\DxAdapter\QueryAdapter;
+
+$data = QueryAdapter::for(User::class)->get()
+```
+bisa juga dengan memanggil class `DxAdapter`.
+```php
+use GhoniJee\DxAdapter\DxAdapter;
+
+$data = DxAdapter::for(User::class)->get()
+```
+
+### Jika menggunakan query atau instance model yang sudah dibuat sebelumnya
+```php
+use GhoniJee\DxAdapter\QueryAdapter;
+
+$qeury = User::query();
+$data = QueryAdapter::load($query)->get()
+```
+bisa juga dengan memanggil class `DxAdapter`.
+```php
+use GhoniJee\DxAdapter\DxAdapter;
+
+$qeury = User::query();
+$data = DxAdapter::load($query)->get()
+```
+
+### Membuat query untuk filter data berdasarkan request: `/users?filter=["name","contains","jhon"]`:
+
+  
+
+```php
+
+use GhoniJee\DxAdapter\QueryAdapter;
+
+  
+$users  =  QueryAdapter::for(User::class)->get();
+
+// semua `User` yang memiliki nama berisi jhon akan didapatkan datanya.
+
+```
+

+  
+
+### Membuat query untuk sortBy berdasarkan request:: `/users?sort=["desc"=>false, "selector"=>"name"]`:
+
+```php
+
+use GhoniJee\DxAdapter\QueryAdapter;
+
+  
+$users  =  QueryAdapter::for(User::class)->get();
+
+// mendapatkan data semua user sorted by ascending name
+
+```
+
+  
+
+[Baca selengkapnya terkait fitur sorting](https://docs.spatie.be/laravel-query-builder/v2/features/sorting/)
+ 
+
+### Membuat query untuk mendapatkan data field tertentu `/users?select=["id","email"]`
+
+  
+
+```php
+
+use GhoniJee\DxAdapter\QueryAdapter;
+  
+$users  =  QueryAdapter::for(User::class)->get();
+
+// mendapatkan data user hanya untuk field id & email
+
+```
+
+  
+

+## Terimakasih
+ - [Team Spatie](https://spatie.be/), karena package ini dibuat berdasarkan refrensi package [Laravel Query Builder](https://spatie.be/docs/laravel-query-builder/v3/introduction). 
+ - [Alfredo Eka WIbowo](https://github.com/edo-floo) yang sudah membuat base DxAdapter.
