Just go on the forums and other parts of the site to learn some basics. Also, watch videos of other people breakdancing on YouTube and such. You could try searching breakdancing or bboy on YouTube, then watch some videos and click on commenters profiles to view their favorite videos. They may have some interesting dancing videos that you may not find just searching ‘breakdancing’ or ‘bboy.’
(Also, I would suggest you do that, practice, maybe learn about the history of breakdancing, and maybe learn about and practice some other dance styles. Learning and practicing other styles can help you learn more about what your body can do and make it easier to learn breakdancing moves if you try to learn moves from other dance styles. It can also help inspire your breakdancing.)
