Wrong installation command on website?

[lpatmo]

npm install -g learnyoumongodb was listed on http://mongodbschool.io/#learn-you-mongodb but wasn't working; I think it was meant to be npm install braz/learnyoumongodb -g as listed on the github repo README?

Same here. The npm install -g learnyoumongodb fails. Here is the link to a gist of the logs: Gist

I can not install as well. It said permission denied.
