 ## API Usage
+>  Comprehensive xero-ruby API usage is showcased here: https://github.com/XeroAPI/xero-ruby-oauth2-app
+
+Here is the basic workflow of using SDK once you have a valid `access_token` (and `token_set`) stored on an instance of the `xero_client`
+
 ```ruby
   require 'xero-ruby'
 
   # reference `Authorization & Callback` to first store a valid token_set on the `xero_client`
   xero_client.refresh_token_set(user.token_set)
 
-  # Accounting API set (https://github.com/XeroAPI/xero-ruby/blob/master/accounting/lib/xero-ruby/api/accounting_api.rb)
+  # Using the Accounting API set (https://github.com/XeroAPI/xero-ruby/blob/master/accounting/lib/xero-ruby/api/accounting_api.rb)
+
+  # Examples
   invoices = xero_client.accounting_api.get_invoices(user.active_tenant_id).invoices
   accounts = xero_client.accounting_api.get_accounts(user.active_tenant_id).accounts
   contacts = xero_client.accounting_api.get_contacts(user.active_tenant_id).contacts
