The Getting Started Guide is intended to help you "get started" with the product. It covers the more general aspects of the product but does not go into the specific detail of each interface.
This is why we include the built-in help for our extensions, which is the second link Jason provided. There is a page for each interface so if you are unsure of what to do, you should be able to get more information by clicking the Help button from the interface.
If you still need help after reviewing the documentation we have provided, then post your question to the forum. We do additional documentation if Support finds that there a lot of repeat questions on a particular feature.
