 ## Define aggregates
 
-Next we need to define the aggregate. So the hotel and how the hotel should behave.
-We have also defined the `create`, `checkIn` and `checkOut` methods accordingly.
-These events are thrown here and the state of the hotel is also changed.
+Next we need to define the hotel aggregate. 
+How you can interact with it, what events happen and what the business rules are.
+For this we create the methods `create`, `checkIn` and `checkOut`.
+In these methods the business checks are made and events are recorded.
+Last but not least, we need the associated apply methods to change the state.
