Modify single event detail view

1. I want to modify the php for the view that appears when you click on an event from the main grid calendar. I’m a little baffled by the naming conventions on your directory structure. I have PRO. Which directory and which specific php file should I modify?

2. When I create my override directory in my theme directory should it be created in “wp-content/themes” or “wp-content/themes/lifestyle”?

3. Should the override directory I create be called “tribe-events” or “tribe-events/community”? There seemed to be conflicting instructions so I thought one of them might have been for the old version.
