Consider moving a copy of Lesson Introduction to lessons themselves

Final comment from Trainer Training: we've found that new Instructors can forget to introduce themselves when teaching for the first time. Perhaps lesson content / instructor notes could include a link to the part of instructor training about Introductions? It's easy to forget what you've covered during Instructor Training when you're teaching for the first time.

Start by locating the Lesson Introduction material in the instructor training content and reviewing how lesson content or instructor notes are organized. Done means deciding which lessons need the introduction reminder and adding the agreed copy or link consistently, with the affected lesson pages identified.
