OK now i seem to know what is git a bit more clear  
it is a reposity that i record the experience in learning git
thanks to liaoxuefeng 
the experience is pretty intersting, though with some displeasure
my english is not that good  things i want to say is just here
at the thought that i can show everyone that is interested in me or happended to see what i build i shall be a lot of pleasure
and now i think the cloud is not that useful again since git helps to deal with a great deal of problems 
created a new branch
Creating a new branch is quick AND simple.
i have another playing idea, which is worth playing.
