Start writing docs.

[mkcor]

Hi @lagru,

Here I'm starting some minimal documentation as per #9.

I'm using the same structure and formats as scikit-image's so we can use the same machinery to build the docs, i.e., generated the rendered HTML pages. I guess we should deploy these somewhere?

I've noticed that

• the scikit-image docs live at https://scikit-image.org/docs/stable/ while
• the NumPy docs live at https://numpy.org/doc/stable/ (no -s).

Maybe it would be more consistent to have doc/src/index.rst instead of doc/source/index.rst?

Thanks for getting this going @mkcor!

I've been thinking about how to keep the effort for the documentation infrastructure low during early development. E.g. start with a Wiki on the Repo? I'm also considering to go "full markdown" for docstubs documentation via MyST?

I'm curious what you think.

Maybe it would be more consistent to have doc/src/index.rst instead of doc/source/index.rst?

I've never really been a fan of the extra doc/source/ folder / level in scikit-image and would love to avoid it here if we can.
