It's a good idea for instructors to shout out their sources when putting together courses on BMF.io. It shows you've done your research and makes your course look way more legit. Plus, it's just the right thing to do—giving credit where credit's due and avoiding any sketchy plagiarism stuff. When students see where you got your info, they trust it more and can even check it out themselves if they're curious. You don't have to go all academic or anything, just a quick mention here and there does the trick. Basically, citing your references keeps things honest and helps you come off as a solid, trustworthy instructor.
