How to play poker

I have written a lot of articles about Texas Hold em, Omaha or other poker games. This time I would like to write something elementary, which is how to play poker.
Basically, there are 8 steps of how to play poker as followings:

Become familiar with poker hand rankings.
Chip in.
Deal or be dealt with.
Look at your cards while everyone else looks at theirs.
Take turns.
Draw.
Go through another around of betting.
Expose your cards.

Variations: Start with 2 cards
7-card stud: Same as 5-card stud but with 7 cards instead of 5. You make the best 5-card hand possible out of the cards that you have.

Hold em: You're initially dealt two cards face down, followed by a round of betting. Then the dealer lays out the "flop" which consists of three cards that anyone can use in their hand. There's another round of betting, followed by another card added to the flop, then another round of betting, and then the final card is added to the flop.

Lowball: The goal is to get the hand with the lowest value

Omaha: Four pocket cards are dealt face down, betting ensues, and then five community cards are dealt face up. A player must make a winning hand using two of the pocket cards combined with the three community cards.

Tips:
You can bluff, or trick the other players into believing you have a powerful hand, by placing high bets. If they fall for it, they'll fold and you'll take the pot with a weak hand.
Aggressive players bet very high early in the game.
Conservative players only stay in the game when their cards are good. They don't lose as much money, but they're easily spotted (and bluffed) by more experienced players.
