When interpreting your full horoscope, using a computer program for casting your chart is a quick and easy way to calculate what once were very complicated mathematical processes.
The interpretation of the chart remains rather involved.
Many professional astrologers are available to interpret your chart and the internet is filled with interpretations of the planets and houses. All you have to do is look. Your soul will always resonate with the interpretations that are meant for your highest good.
Given the large amount of source material available, you are more than capable of interpreting your own chart and the charts of your friends and family.
