S1, have existing repo and change to use git repo to track the change

with remot repo
$ mkdir /path/to/new_repo
$ cd /path/to/new_repo
$ git --bare init

with existing repo
$ cd /path/to/existing_repo
$ git init
$ vi .gitignroe
$ git add .
$ git commit -m “init”

$ git push --set-upstream /path/to/new_repo mastergit

$git remote add origin /path/tocurrent-existinglib fatal: remote origin already exists.$ git remote rm origin
and then add again

Create Developer branch
git branch develop
git checkout develop

======cancel any change in current branch that not yet being staged (add .) ======
git checkout – .

S2, create a new bare repo remotely and then start from local

git clone /path/to/remote/bare/repo

====
check remote repository
git ls-remote

print all branchs
git show-branch -a

Common working process
$ git checkout -b feature/xxx develop

写代码，提交，写代码，提交。。。

feature 开发完成，合并回 develop

$ git checkout develop

$ git merge --no-ff feature/xxx
$ git branch -d feature/xxx
