Ember.js framework usable without Node.js?

Without Node.js installed in a developer machine, is Ember.js still usable, at least to be able to develop and test ember app on local machine? Or Ember framework is totally dependent on Node.js?

Update:

My point is not about the documentation, I just want to ask why it cannot work without node.js isn't Javascript frameworks run in the Browser, why should it be dependent on things like Node.js? Example jQuery runs without node, why Ember cannot work the same way?
