If you wish to update your repository with command line, it is very simple. Today I'll show you how to do that

Step 1: Check branch changes

It’s important to be aware of what’s happening and the status of your changes. When you add, change, or delete files/folders, Git knows about it. To check the status of your changes:

git status

Step 2: Staging your changes

You’ll see any local changes in red when you type git status. These changes may be new, modified, or deleted files/folders. Use git add to first stage (prepare) a local file/folder for committing. Then use git commit to commit (save) the staged files:

git add .

Step 3: add commit

git commit -m "COMMENT TO DESCRIBE THE INTENTION OF THE COMMIT"

Step 4: push changes

For example, to push your local commits to the master branch of the origin remote:

git push origin master

That's it, you have updated your repository.
