Title: Update instructions for newbies like me to contribute.

I had attempted the follow the CONTRIBUTING.md file, but failed to get the tests running. Luckily someone answered my question very quickly, but I think it would save other newbies time and effort if the CONTRIBUTING.md file included the steps to pull down polymer-all and install the node modules.
