instructions cleanup

it appears that git version 1.8.3.4 (Apple Git-47) does not perform a recursive submodule init, so the update does not force node to be downloaded.

These steps worked for me:

$ git clone https://github.com/node-app/Interpreter
$ cd Interpreter/
$ git submodule update
$ git submodule foreach git submodule init
$ git submodule update --recursive

Hi there, thanks for contributing!

Oh, yeah. That's not cool. Does git submodule update --init --recursive (on its own, without the init step) work for you?

[redchair123]

That appeared to work in one command :) The README probably should be updated

[srijs]

I'll handle that :) Anyway, thanks for the heads up!
