 \subsection{printLocationInfo}
 
+This code duplication has been previously avoided with the printRoomInfo()
+method.
+It has been renamed to printLocationInfo(), as part of the commit e52a34789, to
+match the exercise.
+
 \subsection{getExit}
 
+The exit attributes have been made private and a getter was added in commit
+53c427ff3. A switch statement has been used instead of multiple if statements.
+
 \subsection{getExitString}
 
+This method has been added as part of commit ca65af2e2.
+
 \subsection{HashMap, setExit}
 
+Room exits are now stored in an HashMap since commit c9d890b9b. The setExits()
+method has been replaced by setExit() which takes advantages of the HashMap.
+
 \subsection{Vertical direction}
 
-\subsection{keySet}
+In commit 4145a5e8c, the getExitString() method has been modified to be able to
+print the availability of the new exits, used in the stairwell at wing 3. Due
+to the architecture of these rooms, the side exits that were previously settled
+to link them have been kept.
+
+\subsection{keySet ?}
+
+The keySet() method of the class HashMap returns a Set of the keys contained in
+the map.
 
 \subsection{getExitString ?}
 
+The getExitString() method returns a String listing the room's exits.
+To achieve that, it iterates through the exits Map's keys, that is a Set of
+Strings, appending each one to the String that it returns.
+
 \subsection{getLongDescription}
 
+The Room class now uses the previously explained getExitString() method and
+includes the getLongDescription() method that returns the full description of
+the room since commit e510b08d0.
+
 \subsection{Object diagram}
