Build instructions miss information on getting the nightly version of WebKit
It may be just me, but for a newcomer developer it is not clear how to get development version of WebKit. "Building from Source" section in README.md doesn't say anything about that, so the "logical" thing would be to install the development version from package manager, but from what I've read it will always be outdated (and currently, on Fedora 28, it is). I've searched for hours and couldn't find what to do. I feel like the solution should be very simple (if I just want to develop Epiphany and don't want to change WebKit's source code).
Could someone please point me to the right direction?
