Thank you very much for that. It was much needed. I will redirect users to these tutorials.
P.S. You can embed your youtube videos right in your post:

Something that may be of interest as well. In the option panel, you can add custom label to each node and hide/show inputs and outputs. Some nodes like Frame and Transforms Input have options hidden by default.

Thanks - and yes that is useful - I didn't realise the settings changed depending upon which node you were on. Are there any plans to be able to save node trees independently of models? Given that the whole point of animation nodes is that you are defining movement with the object as a variable it would be really useful to have a library of node trees so you could import them into your model and then just assign them to your parts or model.

And I just found out you can animate the camera too, which is cool, so you can do pan and scans, etc ....

You cannot import yet but you can copy and paste nodes between models.

Thanks - useful to know.

@scrubs - any chance of a filter within the library search so you can find the models with animation nodes?

Yes, it will come at some stage.
