Hi,
As an addendum, there is also dedicated wiki pages[0] intended to be of help to newcomers. Not saying that solves everything mentioned before, but it does help quite a lot. As I understand it, the current problem we have is more about the wiki being less organized than there not being sufficient resources or them not being easily accessible to everyone.
