 Add the *payments_mercadopago.MercadoPagoProvider* to your *PAYMENT_VARIANTS* variable. Also to make it available add MercadoPago to your *CHECKOUT_PAYMENT_CHOICES variable*
 
+Mercado Pago doesn't require you to specify a fixed sandbox endpoint, instead they provide you with a sandbox token and a production token, for testing and production, respectively.
+
+Configuration for development
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+```Python
+PAYMENT_VARIANTS = {
+    # ...
+    'MercadoPago':('payments_mercadopago.MercadoPagoProvider',{
+        'access_token': 'MERCADO_PAGO_SANDBOX_ACCESS_TOKEN',
+        'sandbox_mode: True})
+}
+
+CHECKOUT_PAYMENT_CHOICES = [('MercadoPago', 'Mercado Pago')]
+```
+
+If you have any problem using localhost urls as the return value of get_failure_url() or get_success_url() methods try using [ngrok](https://ngrok.com/) instead.
+
+Configuration for production
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
 ```Python
 PAYMENT_VARIANTS = {
     # ...
     'MercadoPago':('payments_mercadopago.MercadoPagoProvider',{
         'access_token': 'MERCADO_PAGO_ACCESS_TOKEN',
-        'init_point': 'sandbox_init_point'})
+        'sandbox_mode: False})
 }
 
 CHECKOUT_PAYMENT_CHOICES = [('MercadoPago', 'Mercado Pago')]
