This ordering is a bit weird IMHO. For example I would never declare /foo/bar before /foo, and therefore it's very error prone. Furthermore, / is also a match for both /foo/bar and /foo, so why would /foo be rendered?

My colleague Roy agrees.

The point is to explain that the order of the routes matters and that redux-little-router uses a simple routing scheme where the order of the Fragments matters.

For example I would never declare /foo/bar before /foo

If you think this will be obvious to everyone using this library, then I guess it's not worth adding it to the README. The code snippet is meant to be an example of what not to do. Perhaps that is not clear enough.

There is nothing wrong with this PR, it's actually very good to have it documented if that's the expected behaviour.

However, I think we should change the library to accept routes in the correct order, instead of documenting what for me is almost a bug.

Thanks for creating the PR though! I wish this was documented before I struggled trying to understand why my routes wasn't working.
