(Dude, you have been ON FIRE with your shares lately! lol)
Product has 3 parts:
>>9-page .pdf
>>11-minute video
>>11-page bonus .pdf
Long story short, you peruse the Google Chrome web store for free apps that could help someone accomplish something. This could be the people on your list, IMers, or almost anyone else.
Download the app, use it for a while, and get to know it really well.
Then create a course on how to use it. The product creator mentions making it a video course, recording with ScreenCast-o-Matic (though you could obviously use anything), then uploading the videos to youtube as unlisted so you don't have to host them.
It goes without saying that the course could be .pdf or video or whatever you want, but video will allow you to best demonstrate how to best use the app.
Create yourself a sales page for your course, then sell it via whatever means make sense.
If it's for people on your list, email them. Put it as a product on warrior+ or JVzoo for IMers. Put it on Udemy or the like for other niches. Whatever...there's not really a "right" or "wrong" way to do it.
All-in-all, I thought it was a simple, but good little idea. It won't be a world-beater, nor will one or two courses like this likely bring you a full-time income. But it could be a way to make a few extra bucks without a whole lot of work on your part up-front.
Plus, you could make this work in niches *other* than IM...which is kinda a rarity for any of these types of products.
