How should we upload files to our own branch in GitHub?

When we are working on a group project with our teammates, usually we need to complete our own part of task and upload to GitHub, but what exactly should we do?

1 . Use "git clone" to clone the files.

2. Use "git status"

We can see now we are in origin/master branch.

3. Create a new branch.

git checkout -b "zequn-test"

4. Use "git status"

We can see we are now in branch zequn-test.

5. We can change our files and use git status.

We can see what we changes on our files.

6. "git add", "git status" and "git commit"

7. Set branch.

git branch --set-upstream-to origin/master

8. "git status" to check.

We should see

On branch zequn-test
Your branch is ahead of 'origin/master' by 1 commit.

9. Push our files.

git push origin HEAD:zequn-test
