1. Setting Up Git

To get started with Git, you'll need to configure your identity:

git config --global user.name "Your Name"
git config --global user.email "[email protected]"

Replace "Your Name" and "[email protected]" with your name and email.

2. Basic Git Workflow

Git has a basic workflow that you'll follow for managing your code:

• Working Directory: The directory where you create, modify, and delete your files.
• Staging Area (Index): An intermediate area where you prepare files for a commit.
• Repository (History): A collection of all commits and their history.

3. Creating a Git Repository

To start tracking your project with Git, navigate to your project's directory and run:

git init

This creates a new Git repository in your project folder.

4. Committing Changes

• To stage files for a commit, use:

  git add <file1> <file2> ...

• To commit your changes, use:

  git commit -m "Your commit message"

Your changes are now saved in the Git repository.

5. Branching and Merging

Branches allow you to work on new features or bug fixes without affecting the main codebase.

• To create a new branch, use:

  git branch <branch_name>

• To switch to a branch, use:

  git checkout <branch_name>

• After making changes on a branch, merge it into the main branch:

  git checkout main
  git merge <branch_name>

6. Cloning a Repository

To work on an existing Git project, clone it to your local machine:

git clone <repository_url>

Replace <repository_url> with the URL of the Git repository you want to clone.

7. Pulling and Pushing Changes

• To fetch the latest changes from the remote repository, use:

  git pull

• To push your local changes to the remote repository, use:

  git push

8. Handling Conflicts

Conflicts may arise when multiple people edit the same file. Git will help you resolve them.

• Open the conflicted file in your text editor and resolve the conflicts.
• After resolving conflicts, add and commit the changes.

9. Git Best Practices

• Commit frequently with meaningful messages.
• Use branches for different features or bug fixes.
• Keep your commit history clean and organized.
• Pull frequently to stay up-to-date with the remote repository.
