What are the specific rules and guidelines for playing Omaha 8 or better?

In Omaha 8 or better, players are dealt four cards and must use two of them along with three community cards to make the best high hand and the best low hand. The pot is split between the best high hand and the best low hand, with the low hand needing to be 8 or lower. Players must use two of their hole cards and three community cards to make their hand. Betting rounds follow each deal of cards, with players having the option to check, bet, call, raise, or fold. The player with the best high hand and the player with the best low hand split the pot.
