repeating the order number in an e-mail

[Driber]

When a customer selects "check/money transfer" as payment option, how can I repeat the order

 

number in the order process e-mail that is sent to a customer after confirming his order?

 

I want to tell the customer in the e-mail: "Please make the payment to <my store name> and include

 

this order number: <order number>"
