This is the first step 1 and part 1 of my tutorial on how to solve a 5x5 5x5x5 Rubik's Cube Professor. The second part covers how to finish the remaining 4 centers. I have placed the link to the second part in the VIDEO RESPONSES section for THIS video.

This part introduces new component descriptions and concepts for solving the 5x5 Rubik's Professor, since there are many more pieces than a regular cube and also more than a 4x4. However, solving the 5x5 is VERY similar to the 4x4, so you should not have that much difficulty getting adjusted to having more edges and center pieces.
Notation Review/Examples:
R = Outer Right face clockwise
u = inner Up face c
