Helping clients get up to speed

Hi. I’m wrapping up a small, but sophisticated WP site for a client. I need to give their Design and Marketing team an overview of how the site works and demo how to make posts and manage the day-to-day aspects. I’m sure I’m not the first person to do this and I was wondering if there were any resources out there that could help me jump start the process.

I know about the written documentation on this site and there are a TON of videos on YouTube, but my client doesn’t have time to read through all that. Most of the videos are more for developers than non-techie users. Is there anything else available?

Thanks!
