Provide a wiki how to update the new manual

[iloveeclipse]

I'm trying to understand how the current code here maps to the state I see at http://spotbugs.readthedocs.io/en/latest/.
I honestly have no clue.

We should provide a simple how to about fixing and uploading the docs.

Its code exists in docs directory in spotbugs project.
How to build is described in docs/README.md.

About .rst format, please refer official document.

Are they helpful enough for you?

A-ha. It means, all the manual.xml ect files in the root of the https://github.com/spotbugs/spotbugs.github.io repo are obsoleted?
We should remove all of them.

After reading https://github.com/spotbugs/spotbugs/blob/master/docs/README.md I still have no clue how the result is deployed to https://spotbugs.readthedocs.io/en/latest/bugDescriptions.html and what is needed for that.

I would prefer we would have a README.md in the root of this repository and explain all the needed points here or at least link to the another readme.
