How to create a new branch with new project in git remote ?

if you just downloaded project to git remote without clone. don't worry you can fix this. :)

You need a project with connections to git and empty folder for clone.
Right click Git Bash Here

git clone YourRemoteRepository  

or  

git clone -b YourBranchname YourRemoteRepository

You should go project folder

cd projectnamefolder

Create new branch

git checkout -b NewBranchName

you should replace your new project with current project. But please don't touch .git and if 2 projects the same please don't touch .gitignore.

you can look is that everything changed?

git status

you can propose changes

git add.

commit

git commit -m YourCommitMessage

finally push remote

git push -u origin NewBranchName

you can merge other branches !! good luck
