: Matching the 60 edge pieces into 12 composite edges.

Usually White and Yellow. Build "bars" of 1x5 pieces and slide them into place.

Unlike a 3x3 cube, which can be solved intuitively with a beginner's method in a few minutes, a 7x7 cube presents unique challenges:

: Once centers and edges are done, solve the cube like a standard 3x3.

If you are stuck, use a digital solver to learn the algorithm sequence. But do not rely on it. The true satisfaction of the 7x7 comes when you finally drop that last layer into place—no software required.
