you should show them keet.io too especially when version 2 is realease any day now teaching on nostr is a little difficult given its new and evolving so fast, but better question why teach at all? i mean there is so many better resources out there that teach for you, so many materials, if you wanted to explain nostr just pull up a youtube or a few episodes from @Thank God For Nostr Podcast , really the days of 'teachers' teaching is over
