Potential improvements for documentation

[j-n-f]

I had a little trouble getting started with this crate.

The documentation for ructe::Ructe is fairly complete and describes everything that needs to be done.

I think this content should be on the main page. The preamble on what ructe is and what it does is good. If there were a section after that like "Getting Started", and then include all the steps from the Ructe page it'd be golden.

If that feels redundant, then a "Getting Started" section that just says "See documentation for Ructe" would be fine.

I think what's confusing is the paragraph before that which effectively says "this is a minimal build.rs." I think it will mislead people into thinking "this is what I have to do to make this work", and they'll be confused when they go to use something under the templates module and find that the compiler can't find it (because of the missing include!(...); this was my experience).

With all that said, cheers for the excellent work. I'm switching to ructe after having issues with tera, and templates rendering nearly 20x faster is really cool.
