A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of JL Audio J2500.1, along with an item. The lack of an instruction or false information given to customer shall constitute grounds to apply for a complaint because of nonconformity of goods with the contract. In accordance with the law, a customer can receive an instruction in non-paper form; lately graphic and electronic forms of the manuals, as well as instructional videos have been majorly used.

What is an instruction?
