Git questions

[Collette Yann]

Hello,

I have 2 questions related to the use of git:

I have cloned the git repository. I have made some changes, for example 
in the file modules/optim/help/en_US/optim.xml.
I want to put the changes into the scilab master repository.
Do I must enter the following commands ?

git branch master refs/remotes/origin/master
git push


To get the YaSp branch, what kind of git commands must I enter ?

git branch YaSp refs/remotes/origin/YaSp
git pull
