+# CambioReal PHP Library
+This library enables you to integrate CambioReal with any PHP application.
+
+## Requirements
+* PHP >= 5.3
+* cURL
+
+## Usage
+### Setup
+To use the CambioReal PHP library you need to setup your app id and app secret.
+``` php
+\CambioReal\Config::setAppId('your-app-id');
+\CambioReal\Config::setAppSecret('your-app-secret');
+```
+
+If you need to change other settings, you can use the following function call:
+``` php
+\CambioReal\Config::set([
+    'appId'      => 'your-app-id',
+    'appSecret'  => 'your-app-secret',
+    'testMode' => true,
+]);
+```
+
+You can change the following settings:
+* appId: your app id. It will be different in test and production modes.
+* appSecret: your app secret. It will be different in test and production modes.
+* testMode: enable or disable the test mode. The default value is _false_.
+
+To create a new API request, just call one of the following methods on the \CambioReal\CambioReal
+class and supply it with the request parameters:
+* \CambioReal\CambioReal::cancel
+* \CambioReal\CambioReal::get
+* \CambioReal\CambioReal::request
+
+request command example:
+``` php
+require_once __DIR__ . 'vendor/autoload.php';
+
+\CambioReal\Config::setAppId('11250214');
+\CambioReal\Config::setAppSecret('6e556ff76e55...56ff7');
+
+$request = \CambioReal\CambioReal::request([
+    'client' => [
+        'name'  => 'John Test',
+        'email' => 'john@test.com',
+    ],
+    'currency'  => 'USD',
+    'amount'    => 130.00,
+    'order_id'  => '10000052',
+    'duplicate' => false,
+    'due_date'  => null,
+    'products'  => [
+        [
+            'descricao'  => 'Laptop i7',
+            'base_value' => 800.00,
+            'valor'      => 1600.00,
+            'qty'        => 2,
+            'ref'        => 1,
+        ],
+        [
+            'descricao'  => 'Frete',
+            'base_value' => 5.00,
+            'valor'      => 5.00,
+            'ref'        => 'São Paulo - SP',
+        ],
+    ],
+]);
+```
