• You won't need any prior experience with Meteor.

• You won't need to consult other sources along the way.
  

Do other resources accomodate for beginners? Yep. But not with this level of depth. As long as you have a basic idea of JavaScript and databases, you'll have a handle on the Meteor fundamentals in a matter of hours. Then, from there:

• You'll know how to talk in the language of Meteor.
  
• You'll be more capable of consulting other resources.
  
• You'll be able to start playing with your own code.
  

Your First Meteor Application is not a definitive guide to Meteor. You won't be a full-fledged developer by the final page. You will, however, understand the core concepts that will make your future education in Meteor a lot more approachable.
