I think it is a good start to ask here, since information on google are really too much, but i think similar concepts or knowledge are more or less the same on most of the webpage. It would be good to view other previous discussion or comments on similar topics in this forum. You will encounter more problems and question definitely afterwards, i think you should not be hesitate to ask more here while you may summarise and tell us your understanding or research on the certain topics or questions you want to make sure your understanding is correct.
