First, create a New Knowledge Base to develop a web application and native mobile applications (Apple and Android) for a Travel agency, named "Travel Agency".
When you press the ‘Create’ button, GeneXus starts the Knowledge Base (KB) creation process.

When the KB has been created, you will see that the contents of the IDE have changed:

- The KB Explorer now displays a tree structure, which will show all the objects in the KB.
- The Output window now shows a report of the actions performed and their results.
