Hi,
Thanks for using our plugins. I can help get you started on this.
For editing templates we have our themer’s guide:
https://theeventscalendar.com/knowledgebase/themers-guide/
The single template starts with this one:
plugins/the-events-calendar/src/views/single-event.php
Which you want to move and edit in your theme here:
yourtheme/tribe-events/single-event.php
There is also more single event modules here to edit:
plugins/the-events-calendar/src/views/modules
Let me know if you have any follow up questions.
Thanks
