 This is the base ruby gem for interacting with the Razorpay API. This is primarily meant for merchants who wish to perform interactions with the Razorpay API programatically.
 
 ## Installation

 ```rb
 Razorpay.setup("merchant_key_id", "merchant_key_secret")
 ```
 
+You can set customer headers for your requests using the following:
+```rb
+Razorpay.headers = {"CUSTOM_APP_HEADER" => "CUSTOM_VALUE"}
+```

 You can find your API keys at <https://dashboard.razorpay.com/#/app/keys>.
 
 If you are using rails, the right place to do this might be `config/initializers/razorpay.rb`.
 
 The most common construct is capturing a payment, which you do via the following:
 
 ```rb
-Razorpay::Payment.fetch("pay-ment_id").capture({amount:500})
+Razorpay::Payment.fetch("payment_id").capture({amount:500})
 # Note that the amount should come from your session, so as to verify
 # that the purchase was correctly done and not tampered
 ```
 
 You can handle refunds using the following constructs:
 
 ```rb
 Razorpay::Payment.fetch("payment_id").refund({amount:500})
+refunds = Razorpay::Payment.fetch("payment_id").refunds
 ```
 
+Refunds can also be handled without fetching payments:
+```rb
+refund = Razorpay::Refund.create(payment_id:"payment_id")
+Razorpay::Refund.fetch(refund.id)
+```
+
 For other applications (such as fetching payments and refunds),
 see our online documentation on <https://docs.razorpay.com>
