Verify Git Installation:
- To verify if Git is installed, run: git --version

Introduction to Git and GitHub

Git is a powerful version control system that tracks changes in your code, allowing multiple people to work on projects simultaneously. GitHub is a web-based platform that hosts Git repositories and provides collaboration tools. Here's a brief overview of common Git commands and how to set up Git using markdown in a README file (usually named README.md).

Git Commands:

git init: Initializes a new Git repository in your current directory.
git clone <repository-url>: Creates a copy of a remote repository on your local machine.
git add <file>: Stages changes for commit. Use git add . to stage all changes.
git commit -m "Commit message": Records staged changes with a descriptive message.
git pull: Fetches changes from a remote repository and merges them into your current branch.
git push: Pushes committed changes to a remote repository.
git branch: Lists all branches in your repository.
git checkout <branch-name>: Switches to the specified branch.
git merge <branch-name>: Merges changes from one branch into another.
git status: Shows the status of changes as untracked, modified, or staged.
git log: Displays a log of commits.

Pushing your Project to git .

Create a New Repository on GitHub:
- Go to GitHub and log in to your account.
- Click on the '+' sign in the upper right corner and select "New repository."
- Give your repository a name, add a description, and choose other settings as per your preference.
- Click on "Create repository."
Navigate to Your Project Directory: Open a terminal or command prompt and use the cd command to navigate to your project folder.
```
cd /path/to/your/project
```
Initialize Git (If Not Already Done): If your project is not already a Git repository, initialize Git in your project folder.
```
git init
```
Add Files and Folders to Git: Use the following command to add all files and folders in your project to the staging area.
```
git add .
```
Commit Changes: Commit the changes you've staged. This step records changes to the repository.
```
git commit -m "Your commit message here"
```
Replace "Your commit message here" with a descriptive message about the changes you made.
Add a Remote Repository: You need to specify the remote repository where your local repository will be pushed.
```
git remote add origin https://github.com/username/repository.git
```
Replace https://github.com/username/repository.git with the URL of your GitHub repository. You can find this URL on your GitHub repository page.
Push Changes: Finally, push your changes to the remote repository.
```
git push -u origin master
```
If you are working with a branch other than master, replace master with your branch name.

Now, your folders and files are pushed to your GitHub repository. Make sure you replace username with your GitHub username and repository with the name of your GitHub repository.
