Good resources to send to people?

Hey all, as I’m preparing the people in my life for my boy to complete his training and start working with me I’ve been getting a crazy amount of hot takes. Funny how many people decide they know everything there is to know about SDs, program vs owner training and why they think there should be a US registration requirement having done absolutely no research into the subject 🙄

I’m honestly exhausted from trying to explain without getting pissy and/or visibly frustrated, and I’m entirely out of spoons to be honest. Does anyone have a link to a website that’s got something like a primer for the general public? I’m probably forgetting something obvious right now but my brain is fried tbh 😅
