Add info about documentation generation to contributing docs

[leplatrem]

make docs :)

[matheuspoleza]

@leplatrem how can I start on that?

[Natim]

Hi @matheuspoleza we are basically using Sphinx doc and the generation takes place using make docs I think you could add a paragraph directly in the contributing page maybe? What do you think?

[matheuspoleza]

@Natim good idea. The paragraph will tell just about the Sphinx and how to run make docs?

[Natim]

Yes, we can also say where will be the generated files and how to open the generated doc.

[matheuspoleza]

cool! I'll do that

You might want to wait a few days first @matheuspoleza. I'm in the process of merging cliquet and kinto -- see glasserc/kinto#1 and #687, and that could have a lot of impact on your work on this bug.

[matheuspoleza]

@glasserc pl, I'll wait that merge.

@matheuspoleza the merge was done and I cloned the bug (see previous ref) thanks for your patience
