To create new courts and halls we will access: 

System -> Courts/Rooms and lookers-> Courts or Halls.

To create new courts, click courts. Here you will see the list of courts we have created, if you don’t have them, the list will be empty.

To create new courts click the icon "New".

We can also remove or modify them. 

To create new Halls we perform the same procedure as with the creation of courts, will show us a series of fields that we can fill out to register it, and will show us the Maximum Capacity field, if we want to limit the room.
