How to push a created repository to github?

Question

git

error: src refspec master does not match any
error: failed to push some refs to 'мойрепозиторий'

This is the error I see. No one except me has access to the repository, did not change anything, what happens at all? It seems like I do the same as it is written on the github itself:

git init
git add README.md
git commit -m "first commit"
git remote add origin адресрепозитория
git push -u origin master
