We should not merge this until #1597 is fixed.

We should also to make sure the landing page of docs and readme of the repo are somewhat consistent (I can take care of that)

[robertnishihara]

Makes sense. Are you referring to the code example? I don't think we need to put the nightly pip installs on the doc landing page.

[robertnishihara]

@richardliaw this is certainly visually cleaner, but people won't know what to do with the wheels. We need to tell them to do pip install -U $WHEEL_NAME so I think we should just include the full command.

How about we make a separate documentation page for "Trying the Latest Version" and move it off of the README?

[robertnishihara]

#1597 has been fixed so there is nothing blocking this PR anymore.

[robertnishihara]

Then you should also remove the documentation for installing on Mac, right?

[richardliaw]

this is fine with me but someone else should also review, as I basically took over this PR..

[robertnishihara]

Shouldn't we remove this documentation page?

[richardliaw]

hm is it not removed?

[robertnishihara]

Oh my mistake.

[robertnishihara]

Looks good to me, I'd suggest merging.

Test failures unrelated - lint passes - merging
