## Part 2: Initializing a Git Repository

1. Navigate to Your Project Directory:
   ```bash
    cd path/to/your/project
   ```

2. Initialize the Git Repository: 
     ```bash
     git init
     ```
   - This command will create a `.git` directory in your project, which tracks all the changes made to the files.

3. Verify Repository Initialization:

     git status
     ```
   - This will show the current status of your project, including any untracked files.

2. Commit Your Changes, After adding files to the staging area, commit the changes with a meaningful message:
     ```bash
     git commit -m "Initial commit for Lab 1"
     ```
3. View Commit History: 
     ```bash
     git log
     ```

1. Create a New Repository on GitHub: Go to [GitHub](https://github.com) and create a new repository.

2. Link Your Local Repository to GitHub: 
     ```bash
     git remote add origin https://github.com/yourusername/your-repository.git
     ```

3. Push Changes to GitHub:
   - Push your local commits to the remote repository on GitHub:

## Part 5: Using SSH: (Optional) 
SSH (Secure Shell) is a protocol that allows you to securely connect to a remote system. When working with Git, SSH is often used to authenticate with remote repositories without needing to enter your username and password each time.
1. Generate SSH Key: 
     ```bash
     ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
     ```
2. Add SSH Key to SSH Agent: 
     ```bash
      eval "$(ssh-agent -s)"
      ssh-add ~/.ssh/id_rsa
    ``` 
3. Add SSH Key to GitHub: Copy the SSH key to your clipboard and add it to your GitHub account under Settings > SSH and GPG keys > Add SSH key.
    ```bash
     pbcopy < ~/.ssh/id_rsa.pub  # macOS
     cat ~/.ssh/id_rsa.pub | clip  # Windows
   ```
 4. Test SSH Connection: 
     ```bash
       ssh -T git@github.com  
     ```
