"Things are only as complicated as they are badly explained."
Proper documentation is essential to avoid struggle and frustration when working with simple things that only seem complicated by not being properly documented and explained.
WHAT KIND OF TUTORIALS?
"Working example is worth thousands of words."
Just like the picture is worth thousands of words the same goes for the working example. Documentation in the form of working examples is proved to be the fastest and the most effective way of transfering knowledge. Sometimes an example is all you need to get the things done. And if there are some accompanying comments that explain what is going on even better. This is the approach I use when creating tutorials. This results in rapid learning which you can apply when you need it in the spirit of Just In Time Support.
