If you don't have a repository locally:

echo “# toutiao” >> README.md
git init
git add README.md
git commit -m “first commit”
git branch -M main
git remote add origin [email protected]:imkf-zhang/toutiao.git
git push -u origin main

have a local warehouse

git remote add origin [email protected]:imkf-zhang/toutiao.git
git branch -M main
git push -u origin main
