 \subsection{back}
 
+The back command was implemented as part of commit f218bf5fa.
+
 \subsection{back test}
 
+The back command works even with any parameter. We will check this later with
+"zuul-with-enums".
+
 \subsection{back back}
 
+When the user enters back twice, he goes two rooms backward. This is working
+correctly.
+
 \subsection{Stack}
 
+The Stack class represents a last-in-first-out (LIFO) stack of objects. The push()
+method allows to add and element at the top of the stack and the pop() method
+allows to retrieve the top item and removes it.
+
+A condition checks whether the Stack is empty before calling the pop() method,
+so that the program does not throw an Exception. This resolve the case when the
+player is at the starting point.
