DOC: remove Table of Contents on the contributing page
State: closed

Currently, the contributing page (https://pandas.pydata.org/pandas-docs/version/1.0.0/development/contributing.html) starts with "Table of Contents". 
This PR removes that, because 1) we do that on none of the other pages in our docs and 2) with the new theme, there is a page table of contents in the right sidebar as well (although this shows, when landing on the page, only the first level)

Is it possible for the right hand side to contain this information? I find some of the sub bullets useful to directly link to
You can of course still link directly to one of the subsections on that pages by clicking the "¶" next to the title, but I see it's a bit more work to get to that link if it is somewhere half that page instead of in the table of contents at the top.

> Is it possible for the right hand side to contain this information?

That's a question for the sphinx theme. Yes, it contains all this information, but the default behaviour is to only show the first level of headings, and only show more levels when you scroll through the page. 
It shouldn't be too hard to change this to a different number of levels that should always be shown (or all levels). That could maybe be a configuration option. 
However, I would personally not be in favor of setting it to all levels, as then the right-side toc would get very long (for many of the pages in the pandas docs, it would get much longer than what can be visible on a single screen), making it less useful as an overview of the page content or to see where you are on the page, I think.
I would agree with @datapythonista in that I think this makes this page harder to navigate

@WillAyd One of the goals of the new theme was to make navigation easier, so if there are things not working for you, concrete feedback is very welcome (in addition to the idea I mentioned above of changing the number of default visible levels in the right-side toc; although I am not fully sure about that myself). 
Now, for this specific case, I assume it is also caused by the long page? 

> Would prefer to keep it, but probably an ideal scenario would be to not have it, but have a better organization of the "Contributing" documentation (more and smaller pages).

Yes, that's what I am planning to do if I find the time (and that will give an overall better result as the stop-gap table of contents). 

So I am also fine with waiting to remove this until that is done. But just note that we have many of such huge doc pages, and in none of the other places we include such a Table of Contents.
Yea I think it's a combination of the length and organization. Right now if say I wanted to link to the section on the C compiler its pretty easy to grab from the top. Getting rid of this would make something like that more difficult.

Agreed this isn't ideal but should wait until a better reorg instead of removing now
@jorisvandenbossche up to you whether to merge or close this. None of the options is optimal, so up to you to decide what's best.
I would prefer to close this unless someone really thinks this is a nuisance to have
Let's close then, doesn't seem this is going to be merged, and we start to have too many open PRs.
