README has broken link to online tutorials

README has broken link to online tutorials.

If it was intentional to remove the online (web) API tutorials, then this repo's README should be edited to remove link.

And then also Issue #2 : Repo tutorials do not match online tutorials can be closed.

If we kill the link and just have users browse the code here on GitHub, we can close #2 and #6 too. DRY.

Do the online tutorials even exist anymore ?
