```bash
$ git init

``` 
### Show modified files in working directory, staged for your next commit

```bash
$ git status
On branch master

No commits yet

Untracked files:
  (use "git add <file>..." to include in what will be committed)
        Readme.md
        image.jpg

nothing added to commit but untracked files present (use "git add" to track)
```
### Add a file as it looks now to your next commit (stage)
