What is meant by the guiding function of prices?

Please provide the best answer for the statement.

The guiding function of prices refers to the response of producers to changes in prices. With a given supply schedule, if demand increases, the market equilibrium price will rise and producers will respond to that by producing an increased quantity of the product. Also, there may be entry of firms into the industry. Conversely, if demand decreases, the market equilibrium price will fall and producers will respond to that change by producing a decreased quantity of the product. There may also be an exodus of firms from the industry. The market system is a communications system and prices are the way information is communicated and incentives are given to take action.
