Read everything you can find. There will be differences between care sheets as different methods work with different people but the basics will, for the most part, be consistant.
Get the 'Bearded Dragon Manual', it has great information about bearded dragons and info about breeding. Also pick up 'Your Bearded Dragon's Life' by Liz Palika , she gives a very good account about all the stages of a dragon's life. Read the forum here regularly, as alot of answers can be found just by reading regularly. Once you have learned all you can by reading, if you have specific questions or confusion about certain aspects of Dragon care, feel free to ask and we can do our best to clarify.
