+If you know the address of a contract, you can access all keys and values stored by that contract
+using the [`contract_storage{:rust}`][app_contract_storage] and [`contract_storage_mut{:rust}`][app_contract_storage_mut]
+methods. The following example assigns a value to a key in a similar way to how the contract would (line 11)
+and then reads this value on line 15. These methods are giving easy and simple access to the
+storage of any contract.
