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 ?

And giving it your github credential as mentionned in the Setting Up Git lesson that is link in the lesson you are following.
