I read an article today. Here is a sentence :
A fifty-something Minneapolis lawyer named John Hideraker sits down in his kitchen with a laptop and some simple software and cooks up a website.
i know cook up means
a.to concoct or contrive, often dishonestly. eg,She hastily cooked up an excuse.
b.to falsify.eg Someone had obviously cooked up the alibi.
[b]what does “cook up” mean in this sentence?
