+
+
+## Installation
+
+First you need to [install composer](https://getcomposer.org/doc/00-intro.md#installation-linux-unix-osx)
+
+
+
+1)  Add dependency to composer.json file.
+ ```
+    "capynet/DrupalPayPalRecurrringPayment": {
+        "type": "package",
+        "package": {
+            "name": "capynet/DrupalPayPalRecurrringPayment",
+                "version": "dev-1.x",
+                "type": "drupal-module",
+                "source": {
+                    "url": "https://github.com/capynet/DrupalPayPalRecurrringPayment.git",
+                    "type": "git",
+                    "reference": "master"
+                }
+        }
+    }
+ ```
+2)  Once the module is installed DrupalPayPalRecurrringPayment dependency will need to be installed.

+
+
+### Notes
+
+####Taxes
+The tax is being hardcoded and it seems it is not being used. We still need to improve the code.
+
+ ```
+   $chargeModel->setType('TAX')
+      ->setAmount(new Currency(array(
+        'value' => $data['payment_amount'] * .21,
+        'currency' => $data['payment_currency']
+      )));
+ ```
