OP here, thank you all for your kind and insightful comments. There are a lot of very talented fzf users here!

I wrote this post following diataxis.fr's advice on writing tutorials:

>A tutorial must help a beginner achieve basic competence with a product, so that they can go on to use the product for their own purposes.

>A tutorial also needs to show the learner that they can be successful with the product - by having them do something both meaningful and attainable.

I think I have succeeded on that front judging by the reaction. :)
