Can you explain the rules for playing a game of 7 card no peak?

In a game of 7 card no peak, each player is dealt 7 cards face down. Players cannot look at their cards until it is their turn to play. The goal is to form the best hand possible using the cards dealt. Players take turns either drawing a card from the deck or picking up the top card from the discard pile. The game continues until a player declares they have the best hand and wins the round.
