Meteor 1.3 brings a lot of awesome improvements, but I feel like all these changes can also make it harder for newcomers to figure out where to start. So I decided to try and address this by writing a study plan:

This is a complement to the awesome Meteor Guide, it basically tells you what to read and in what order.
Of course a lot of this is based on my own experience and opinions, so I would love to get feedback, or know if I missed anything!
