an academic tutorial for hal

hi all
I'm very pleased to know about linuxcnc and it's amazing abilities specially in the field of HAL programming and the ability to deal with kinematics
but i found that the manuals that is added are not enough as a tutorials for beginners so
:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
is it possible :
that the very professionals to design a tutorial that begins from the early beginnings and moves gradually by samples and could they prepare something like video lec.s to complete that """" the most important thing in the enviroment of linux is that ,,,,,, there is no enough tutorial and they assume that all users and whom want to achieve any progress are professionals from the beginning
please this is a wonderful way to help spreading of that extremely wonderful enviroment

You are wellcome to puplish any documentation.
And i am pretty sure that non of us with push rights will refuse to include the additional or rewoked documentation.
