in oder to learn more about git and github, I created this project.

Init:

echo "# DEMO1" >> README.md
git init
git add README.md
git commit -m "first commit"
git branch -M main

VSCODE：
git remote add origin https://github.com/XLYing23333/Demo1.git
Debian Terminal：
git remote add origin [email protected]:XLYing23333/EX1.git
change: add -> set-url

git push -u origin main
