Reworded 'Isolate the problem' and added link

Not sure if you want all examples there, but reworded awkward sentence and added examples link you had in README.md.

Before doing this i did update README.md, but left just the link you had there. I was going to remove it but thought you wanted it highlighted more.

Maybe add these other links there too?
