This is a To Do list application, where you can list your activities.
First you have to download your node_modules using 'npm install', then add your username and password from your MongoDB Atlas account to your 'mongoose.connect' link and run app.js using node or nodemon.
All you have to do is write localhost/[Your page name] as the URL.
Ex : localhost/work
localhost/home
Since the application is connected to MongoDB Atlas, you can write whatever you want and return later, it will remain the same.
