https://www.theodinproject.com/lessons/foundations-git-basics this is the lesson that i am following. I completed the Create the Repository section successfully. I also completed the Use the Git Workflow section successfully. It’s the Modify a File or two where I am facing all the difficulties.
Can someone please show me the way how to do it ?


Theoretically yes, but I would recommend the terminal git brings with it. You should be able to just open any location on your drives, right-click, and select “GitBash here”. This will start a terminal with the directory you were in as the working directory.
