+## Description
+
+This is  MERN auth application 
+
+
+It includes the following:
+
+- Backend API with Express & MongoDB
+- Routes for auth, logout, register.
+- JWT authentication stored in HTTP-only cookie
+- Protected routes and endpoints
+- Custom middleware to check JSON web token and store in cookie
+- React frontend to register, login, logout.
+
+## Usage
+
+- Create a MongoDB database and obtain your `MongoDB URI` - [MongoDB Atlas](https://www.mongodb.com/cloud/atlas/register)
+
+### Env Variables
+
+Rename the `.env.example` file to `.env` and add the following
+
+```
+PORT = 4000
+MONGO_URI = your mongodb uri
+JWT_SECRET = 'abc123'
+```
+
+Change the JWT_SECRET to what you want
+
+### Install Dependencies (frontend & backend)
+
+```
+cd backend
+npm install
+cd frontend
+npm install
+```
+
+### Run
