Altium is a fairly robust program, taking a somewhat different approach to design compared to the industry leader OrCAD. Your schematic and PCB layout are all done from the same program in the same window. It has, in the short time I've been using it, proved itself easy to use.
However, this was only the result of an Altium employee turning me to a set of various tutorials on the software package. I felt like it would be important for the community to have the same links I received:

With more specific and focused attention here:

Enjoy. I am currently going through right now.
