README suggests this is just QuickCheck rebranded

[andreasabel]

Hi, I was passing by here and looked into your shop window (README).
As QuickCheck user, I did not find anything that I not already had, so I was not attracted into your shop.

Maybe the README could be improved to tell me what hedgehog can do that QuickCheck cannot. (Classic related work section.)

Yes, the headline says "automatic" generation of test cases, but the example shows that the linear range is defined ahead of time, which I could just do in any other test library. I want to understand what it means by automatic.

Yeah fair criticism!

The readme is currently not assuming anything about the reader, but obviously many (all?) Haskellers are or have been QuickCheck users.

It would be good idea to have a section about QuickCheck and how it compares. @edsko has a wonderful blog post Integrated versus Manual Shrinking on the topic.
