[Discussion] Document template (readthedocs?)

[yuki-koyama]

Recently, readthedocs https://readthedocs.org/ has become more and more popular. Should we use it?

Pros:

• Beautiful template (sphinx_rtd_theme https://sphinx-rtd-theme.readthedocs.io/) available

Cons:

• Need to learn reStructuredText http://www.sphinx-doc.org/en/master/usage/restructuredtext/basics.html and rewrite existing docs to it

As an alternative choice, MkDocs https://www.mkdocs.org/ may be worth investigating, which allows us to use Markdown.

By using sphinx_rtd_theme, the issue #19 can be resolved.

libigl also uses MkDocs for documentation: http://libigl.github.io/libigl/

I changed the way of managing the document.
