Quick setup — if you’ve done this kind of thing before

…or create a new repository on the command line

echo "# vue3" >> README.md
git init
git add README.md
git commit -m "first commit"
git branch -M main
git remote add origin https://github.com/qwe8851/vue3.git
git push -u origin main

…or push an existing repository from the command line

git remote add origin https://github.com/qwe8851/vue3.git
