-PayPal integration for Nette
+MetisFW/PayPal
+======
+
+[![Build Status](https://travis-ci.org/MetisFW/PayPal.svg?branch=master)](https://travis-ci.org/MetisFW/PayPal)
+[![Downloads this Month](https://img.shields.io/packagist/dm/metisfw/paypal.svg)](https://packagist.org/packages/metisfw/paypal)
+[![Latest stable](https://img.shields.io/packagist/v/metisfw/paypal.svg)](https://packagist.org/packages/metisfw/paypal)
+
+About
+------------
+PayPal payment integration to Nette framework.  
+Internally use [paypal/PayPal-PHP-SDK](https://github.com/paypal/PayPal-PHP-SDK) for api requests.
+
+Inspired by [Kdyby/PayPalExpress](https://github.com/Kdyby/PayPalExpress)
+
+Requirements
+------------
+MetisFW/PayPal requires PHP 5.3.2 or higher with curl, json and openssl (for lower PHP version) extensions.
+
+- [Nette Framework](https://github.com/nette/nette)
+
+
+Installation
+------------
+1) The best way to install MetisFW/PayPal is using  [Composer](http://getcomposer.org/):
+
+```sh
+$ composer require metisfw/paypal
+```
+
+2) Register extension
+```
+extensions:
+  payPal: MetisFW\PayPal\DI\PayPalExtension
+```
+
+3) Set up extension parameters
+
+```neon
+payPal:
+  clientId: AUqne4ywvozUaSQ1THTZYKFr88bhtA0SS_fXBoJTfeSTIasDBWuXLiLcFlfmSXRfL-kZ3Z5shvNrT6rP
+  secret: EDGPDc3a65JBBY7-IKkNak7aGTVTvY-NhJgfhptegSML58fWjfp89U7UKNgGk9UI-UEZ-btfaE2sGST1
+  currency: EUR
+  sdkConfig:
+    mode: sandbox
+    log.Enabled: true
+    log.FileName: '%tempDir%/PayPal.log'
+    log.LogLevel: DEBUG
+    validation.level: log
+    cache.enabled: true
+    # 'http.CURLOPT_CONNECTTIMEOUT' => 30
+    # 'http.headers.PayPal-Partner-Attribution-Id' => '123123123'/
+```
+
+sdkConfig is config to [paypal/PayPal-PHP-SDK](https://github.com/paypal/PayPal-PHP-SDK)
+see [sdk-config-sample](https://github.com/paypal/PayPal-PHP-SDK/blob/master/sample/sdk_config.ini)
