SDK Getting Started

SOLVED

I am a senior developer who is VERY new to Sage. I haven't ever used it or even seen it. A client wants me to use the SDK to get some very basic invoice and payment information out of Sage 50, but even the "Getting Started" info around here seems a little overwhelming. I only just started reading what's already on the forums and blogs here, but if someone can point me directly to a good how-to tutorial without all the accounting-speak, it would sure save me some time and money. Thanks in advance.
