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

This happens if you initialized a new github repo with README and/or LICENSE file

git remote add origin [//your github url]

//pull those changes

git pull origin master 

// or optionally, 'git pull origin master --allow-unrelated-histories' if you have initialized repo in github and also committed locally

//now, push your work to your new repo

git push origin master

Now you will be able to push your repository to github. Basically, you have to merge those new initialized files with your work. git pull fetches and merges for you. You can also fetch and merge if that suits you.

The error possibly comes because of the different structure of the code that you are committing and that present on GitHub. It creates conflicts which can be solved by

git pull

Merge conflicts resolving:

git push

If you confirm that your new code is all fine you can use:

git push -f origin master

Where -f stands for "force commit".

If this is your first push

just change the

git push <repo name> master

change it like this!

git push -f <repo name> master
