Issue pushing new code in Github

I created a new repository on Github which has only Readme.md file now.

I have a newly created RoR project which I wanted to push to this repository. Following are the commands I gave in my Terminal to execute this along with the error I am getting.

git remote add origin https://github.com/aniruddhabarapatre/learn-rails.git

After which I entered my username and password

git push -u origin master

Error ---

To https://github.com/aniruddhabarapatre/learn-rails.git
 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to 'https://github.com/aniruddhabarapatre/learn-rails.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first merge the remote changes (e.g.,
hint: 'git pull') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

This is my first time pushing my code to a Github repository and I'm lost with the errors. I searched few other questions that are asked here, but none of them had issues first time.

If this is your first push, then you might not care about the history on the remote. You could then do a "force push" to skip checks that git does to prevent you from overwriting any existing, or differing, work on remote. Use with extreme care!

just change the

git push **-u** origin master

change it like this!

git push -f origin master

When you created your repository on GitHub, you created a README.md, which is a new commit.

Your local repository doesn't know about this commit yet. Hence:

Updates were rejected because the remote contains work that you do not have locally.

You may want to find to follow this advice:

You may want to first merge the remote changes (e.g., 'git pull') before pushing again.

That is:

git pull
# Fix any merge conflicts, if you have a `README.md` locally
git push -u origin master
