unclear instructions / problem with install / how do I run it

[rob-lindman]

I believe I am within inches of being able to run depthy (which is a cool tool!).

I am experiencing some issues when running grunt build, and I am not sure how to run it.

note two issues in the codepile... a typerror, and a fatal error related to gifsicle.

After I can fix it, then i need to know if I can run it with PM2 or?

The instructions aren't exactly precise and this error is not mentioned afaic.
