Everybody knows how to backup but the important thing is to know how to restore from that backup.

I’m thinking this POV often is missing when discussing documentation of software. The Wikipedia article on Software Documentation is focusing a lot on pigeonholing the different type of documentation that may exist so that no type is left out. That’s sometimes what I feel myself when trying to document a process - have I really made sure that this way of documenting is #1 or should I just go over the alternatives again?

Hold your horses. From now on, every inch taken towards documenting something must be questioned.
