​Suggested Clarification in Trailhead Example

https://developer.salesforce.com/trailhead/force_com_introduction/data_modeling/object_relationships

In the Creating the Junction Object section - the third bullet point under #3 refers to the “custom tab wizard” - it is unclear to what this is referring.
SonamSonam (Salesforce Developers) 
At the time you are creating a new Object, when you are about to save it - the UI custom object creation wizard(wizard is a step by step process of creation of this object) gives you an option to launch the custom tab wizard(step by step process to create a tab to represent the newly created object)..so it takes about not launching this wizard as you do not need a tab for this junction object.
