1. add description about connection
   2) create project stub with server and clients part (https://github.com/alt-j/fast-react-seed)

Some explanation on How this package works would be helpful.

For example you can see: https://github.com/alt-j/fast-react-seed.
But now, its only blank, I'll make it more useful in the nearest time.

@alt-j Cool lib! though as above, a sentence or two about what you are doing differently would be awesome?

[alt-j]
