+# GameController
+
+The GameController acts as the main entry point for controlling the poker game logic from the server.
+
+The server does not manipulate the game state directly.
+Instead, it interacts exclusively with the `GameController`, which internally coordinates:
+
+- the GameEngine
+- the GameState
+- the RuleEngine
+- the RoundManager
+- the TurnManager
+
+# How the Server interacts with the GameController
+
+The server calls methods on the GameController to control the game.
+
+## Starting a Game
+
+```java
+GameController game = new GameController(engine);
+
+game.addPlayer("Julian", 20000);
+game.addPlayer("Mathis", 20000);
+game.addPlayer("Jona", 20000);
+game.addPlayer("Lars", 20000);
+
+game.startGame();
+```
+
+Steps performed:
+
+1. Create a GameController instance.
+2. Add players with their starting chip stacks.
+3. Start the game.
+
+When `startGame()` is called:
+
+- the deck is prepared 
+- hole cards are dealt
+- the game phase switches to PREFLOP
+
+## Preflop Actions
+
+During the preflop phase, players perform actions.
+
+```java
+game.playerCall("Julian");
+game.playerFold("Mathis");
+game.playerCall("Jona");
+game.playerRaise("Lars", 1200);
+```
+
+Supported actions include:
+
+* `playerCall(playerId)`
+* `playerFold(playerId)`
+* `playerRaise(playerId, amount)`
+
+The GameController passes these actions on to the GameEngine, which validates them using the RuleEngine.
+
+## Flop
+
+Once the preflop betting round is completed, the server can deal the flop.
+
+```java
+game.dealFlop();
+```
+
+This will:
+
+- draw 3 community cards
+- add them to the board
+- update the game phase
+
+## Turn
+
+```java
+game.dealTurn();
+```
+
+This deals the fourth community card.
+
+## River
+
+```java
+game.dealRiver();
+```
+
+This deals the fifth and final community card and starts the final betting round.
+
+## Showdown
+
+After the final betting round, the server can determine the winner.
+
+```java
+String winner = game.showdown();
+````
+
+This will:
+
+- evaluate the hands of all remaining players
+- determine the best poker hand
+- award the pot to the winner
+- end the current hand
+
+Example:
+
+```text
+Winner: Julian
+Pot: 3200
+```
+
+During the showdown, each remaining player's hand is evaluated using their:
+
+- two hole cards
+- five community cards
+
+The best possible 5-card poker hand wins the pot.
+
+# Server Outputs
+
+The server can query the current game state at any time.
+
+## Get full game state
+
+```java
+GameState state = game.getState();
+````
+
+Returns the complete game state.
+
+The state includes information such as:
+
+- players
+- chip stacks
+- pot
+- current game phase
+- deck state
+
+## Get community cards
+
+```java
+List<Card> board = game.getCommunityCards();
+```
+
+Returns the community cards currently on the board.
+
+The number of cards depends on the game phase:
+
+- Flop -> 3 cards
+- Turn -> 4 cards
+- River -> 5 cards
+
+Example:
+
+```text
+[NINE of DIAMONDS, TEN of SPADES, JACK of CLUBS]
+```
+
+## Get player hole cards
+
+```java
+Map<String, List<Card>> cards = game.getPlayerCards();
+```
+
+Returns a mapping of player IDs to their hole cards.
+
+Each player receives two private cards at the start of the hand.
+
+```text
+playerId -> [Card, Card]
+```
+
+Example:
+
+```text
+Mathis -> [NINE of DIAMONDS, TEN of SPADES]
+Lars   -> [JACK of SPADES, TWO of HEARTS]
+Jona   -> [SEVEN of DIAMONDS, TWO of DIAMONDS]
+Julian -> [NINE of HEARTS, FIVE of DIAMONDS]
+```
