Getting to grips with Quartus II

The best way is to read the documentation:

http://www.altera.com/support/software/sof-quartus.html

Specifically the handbook:

http://www.altera.com/literature/lit-qts.jsp

If you are a Xilinx user this will seem foreign to you as documentation is almost non-existent in the Xilinx world. However, Altera's documentation is usually quite thorough.

Aside from that, practice makes perfect. Quartus II is a very powerful piece of software. The online help within Quartus is pretty good as well.

If you come across an error or warning during compilation you can right click on the error and select "Help" which will usually provide you with a description of the problem and a generic solution.
