Possible sections to be added to docs

1. Wires - I saw some commits about this but don't think I've seen any documentation explaining the motivation, usage, etc.

2. Discussion on controlled components, particularly with regard to Signals I suppose; this is probably all very obvious to someone with more experience with React or similar, but I think it is worth a small but prominent mention in the documentation; many of the issues I've had could have been avoided by making my signals controlled from the start, which is not the default behavior (nor should it be).

I haven't mentioned wires in the readme because they are very experimental. They are a way to provide shared state, but I don't think I like the current API since it doesn't let you nest bits of state properly. Most likely the API will be changing in the near future.

Good point about the controlled component. I left them as-is because, as you mention, they come from React rather than Concur. However I can add some explanation of the mechanism. I'll leave this issue open until we have that.

It would also be very helpful if you could open a PR documenting your experience with them. As the API implementer, I may not have the right take which would help people new to both Concur and React, however I can refine your explanation further and add exposition.
