Smoother quick start

[dfredell]

Adding depth of 1 to the git clone to save on network and disk space as only the HEAD is needed for an install.
Also adding permission to execute the index.js file.

Adding a --depth 1 saves about 50% (21M vs 40M) of network and disk.

By default the index.js doesn't have execute permission
