If you have any book on Vedic astrology, you can find substantial information on it.
I not sure if you get any books on Vedic astrology in the country you live. If you do you can always pick up a basic book on Vedic astrology. You will learn the basics then it would be very easy for me to guide you. You may also read some basic articles on Vedic astrology on the Internet.
