The OpenDX Virtual Workshop modules are geared to the beginner, but they include additional information which will be applicable to different readers depending on your background and goals. The additional information is keyed by the icons below. The icons themselves are not links; if a link is part of the information, it will appear as a text link to the right of the icon. Please read through this key to decide which of these will pertain to you:

	Hint: Additional helpful information, similar to, but less technical than Pro Tips.
	Pro Tip: This is for the advanced programmer who is ready for professional details.
	Technical aside: These are optional sections for those who want to see all information related to the current topic.
	Exercise: This is homework to do on your own.
	Viz Quiz: Short, inline brainteaser: We highly recommend that all participants work through these. They are an integral part of understanding the material.
	Brain Busters: Thought experiments; helpful, but not required.
