The main issue what windows os users face while practicing git or GitHub is that, most of the YouTube tutorials have given codes for MAC OS
The mistake what we do is that we try to run those MAC OS codes in windows command prompt but what we have to do is that we have to run in "Git bash "
Now where do we get this Git bash and how do we open this
First download git %[git-scm.com/downloads]
Go to the particular folder where you have to save your folder in "c" or "d" drive
Then right click and press show more options
Now press git bash here ,now you can type the same code which runs in MAC OS
