Although I've tried to make the collection somewhat hierarchical on two levels, it is not strictly so. The first level is the bold titles. When I was first learning I progressed from naked and hidden sets, to X-wing, XY-wing, coloring, UR's, nice loops, and then to some of the advanced techniques. Under each bold title the methods are again somewhat hierarchical. After learning the basics, for example X-wing, I then gradually picked up the more involved techniques, for example turbot fish and then X-cycles. There is not a lot of dependency between the techniques - you can understand X-cycles without ever understanding an X-wing, but understanding the simpler techniques sometimes makes the more complicated ones easier and you will probably use the simpler ones more often for many published puzzles.
One approach is to delve into a topic that interests you - generally this happens when I get stuck and a solver tells me to use some technique and I want to understand what it really means. Mostly enjoy the puzzles and don't get too caught up in the techniques!
