i want to know to know about twitter bootstrapp clearly does any one have good and easily understanding tutorial

I have used Twitter Bootstrap for several projects and it really helps you a lot if you are concerned about productivity. When I started out I actually oly used this website: http://getbootstrap.com/getting-started/

Of course it all comes down to how much web dev experience you have? Because using Twitter Bootstrap only requires you to have at least a decent amount of knowledge in HTML and CSS.
