Got error when installing expressjs.com locally

I have provided my command line screenshot so that someone should got my point

it looks like, you are inside of your Express/ directory which is inside "Code PlayGround"/ directory.
and the git's error message is may be you have already a folder or directory "express.js.com/" directory already exist in your express/ directory (your current directory where you want to clone the repo).
try using ls command and see if it already exists then use that folder or directory

you can also provide the screenshot after doing ls, that would be helpful as well

also from my side try learning basics of git , if you are new to to git or version control
