The most common beginner-friendly way is the layer-by-layer method, which breaks it into manageable chunks:
White cross
Make a white plus sign on one face, matching the edge colors with the center pieces.
White corners
Finish the white face by placing the white corner pieces correctly.
Middle layer edges
Solve the four edge pieces in the middle layer (no yellow on these).
Yellow cross
Form a yellow plus on the top (orientation only, not position yet).
Position yellow edges
Line up the yellow cross with the side centers.
Position yellow corners
Put the yellow corners in the correct spots (even if twisted).
Orient yellow corners
Twist the yellow corners to finish the cube 🎉
Excellent ! But this explanation only goes for 3by3 cube. Have you solved 4by4?
