Here are the steps to be followed installing and setting up Git on a Windows machine using a GitHub account:

Download and install the latest version of Git.

Set your username in Git:

• open Git Bash
•  $ git config --global user.name ‘Mona Lisa’ 
•  $ git config --global user.name
 > Mona Lisa

Set your commit email address in Git:

• open Git Bash
•  $ git config --global user.email ‘email@example.com’ 
•  $ git config --global user.email 
 email@example.com 

If you haven't already done so, go to your GitHub account and create a new repository. On your local machine navigate into the folder you want to link with the repository.

Initialize Git in this folder with  $ git init  and  $ git remote add origin https://github.com/git_profile_name/repo_name.git .

Now you can check the Git status with:  $ git status .

If not already done, add a .gitignore file to your project.

If there's already something to push, you can stage it with:  $ git add * . If successfully staged, the files can be commited:  $ git -m commit ‘message’. After this step it can all be pushed to the remote repo:  $ git push -u origin master .
