In LMS section we used our SP LMS extension (details & demo) , which was fully described here : joomshaper.com/documentation/joomla-extensions/sp-lms

All you have to do is add your custom content instead dummy ones. But if you don't use QuickStart you have to:

• Install component and all modules
• Add Course Categories then Courses
• Add Teacher(s) then lessons
• Create Events if you need them and assign Speakers
• Add new menu items using SP LMS component views
