Add your name inside the file

Cool story bro!

but how can I update my repo?

going to be commited

git status# On branch master## Initial commit## Untracked files:# (use "git add <file>..." to include in what will be committed)## readme.txtnothing added to commit but untracked files present (use "git add" to track)

Add readme to stage

This command adds readme.txt (or changes in readme.txt) to staging area

Alternative adding all files to stage

This command adds (add) all (deleted/created/modified) files to staging area

git status# On branch master## Initial commit## Changes to be committed:# (use "git rm --cached <file>..." to unstage)## new file: readme.txt#

Commit changes

git commit -m “Initial Commit”

This command creates the commit containing the staged changes

Now add your email to readme.txt
