It's not a single digit minute read, but to me "Git from the Bottom Up" was what really made me understand git a long time ago.

git's the kind of tool where understanding how your commands operate on the underlying data structures will probably make it a lot easier to use efficiently. (And they're beautifully simple despite how powerful and flexible they are)

As a tool you might be using for hours per week for a few more decades, it's worth the investment going beyond the "in x minutes". I tend to provide both to juniors.

Is is better than the Git Internals book?
