Thanks @odow, I suspected this wouldn't quite work. I think the best way forward would be for me to make a JuMP specific readme like I did for InfiniteOpt. I should have time to do that this week.

Another option would be to cleanup the readme since most of it is replicated in the docs.

This along with improving the docs is on my TODO list, I just need to find the time :)

I think I fixed the vale errors

[pulsipher]

Hold off on merging, I found a few typos I should correct first...

[odow]

Typos that vale didn't catch? Interesting

[odow]

Merging because we can always update later. I don't see the typos @pulsipher is talking about.
