Learn basic astrology first
Geminian,
Rather than starting out with trying to understand complex charts, instead, start with the easiest chart of all...your birth chart. After all, you are an EXPERT about you. To learn the basics of interpreting your birth chart, go here:

And, when you are ready, to make things even easier, only look at synastries (chart comparisons between two people) or "just plain" composites (chart combinations between two people). "Progressed composite" is just too much complexity!
Keeping it simple,
Tim
