How to add files?

To add files to your Git repository, follow these steps:

Navigate to your repository: Open your terminal and change to your project directory:
```
cd /home/labex/project/my-time-machine
```
Create or modify files: You can create a new file or modify an existing one. For example, to create a new file:
```
echo "Hello, World!" > hello.txt
```
Add files to the staging area: Use the git add command to stage the file(s) you want to include in your next commit. To add a specific file:
```
git add hello.txt
```
To add all files in the directory:
```
git add .
```
Check the status (optional): You can check which files are staged for commit by running:
```
git status
```
Commit the changes: Finally, commit the staged files with a message:
```
git commit -m "Add hello.txt file"
```

This process will add your files to the repository and save the changes. Let me know if you need further assistance!
