Full Steps to start a git project

Create a remote Gitee repository.
Create new branches as you wish. (Generally, you should create several branches as many as your team member)
Create a local folder to retrieve initial files from the remote Gitee repository.
Open the local folder with VS Code.
Use "Ctrl + Shift + ` " to open terminal in VS Code.
Next, follow the steps to gitify your local folder.
- git init - initialized empty Git repository
- git remote add origin https://gitee.com/xxxx/xxxx.git - add remote repository
- git pull origin <remote_branch_name> (like git pull origin dev_example) - pull and obtain remote code to local folder
- git checkout -b <local_branch_name> (NOTICE: the <local_branch_name> should be exactly the same as remote one. Like git checkout -b dev_example) - create local branch to associate with remote one
So far, you have clone the project to your local folder which is connected to the remote repository as well.
To synchronize local change to remote one, please use these steps below.
- git add "newChageFile.xx" - add new file
- git commit -m "new change explanation" - add change explanation
- git push origin <your_branch_name> (like git push origin dev_example) - push your change to your remote branch
Until now, for a common developer in a team, these commands are far enough.

If you are going to merge members' change to the project, you should follow the additional steps below.

git checkout master - go to master branch
git pull origin <member_branch_name> (like git pull origin dev_example) - get member's change
git push origin master - update this member's change to the project
Repeat steps 1-3 until all members' changes have been updated.
