Going through the updated doc right now. Not sure why we 'deselect' Enable docker, and leave all the others checked. Any reason?

That's a good question. I think you're referring to the todo tutorial: https://loopback.io/doc/en/lb4/todo-tutorial-scaffolding.html#create-your-app-scaffolding, right?
I think we should recommend users to accept all the defaults.

Thoughts? @strongloop/loopback-maintainers

Thanks for adding that commit @emonddr!

@dhmlau @emonddr I think the reason was because the option says it adds docker files to the application and there aren't any docker files in the example. So either we can add the files, or keep the option disabled. I'm fine with adding them though.

Personally, I'd prefer to keep all the defaults in the "features" prompt and make the necessary changes in the example app.

Nice job :D
Just have one concern about hasOne & belongsTo. The rest are just some nitpicks.
