+## Production Guide
+This is a setup guide to host the server on AWS EC2. It's assuming you already have an account setup and know about free tier limitations.
+#### Setting up EC2 
+1.  Select the EC2 Launch Instance Wizard choose Ubuntu(22.04 x86) as your OS under AMI section. 
+2. Choose t2.micro instance if you want to stay within free tier or your preferred instance type and head to  the next section.  Keep configuration as default.
+3.  Select the storage you need, 20 GBs should be more than enough and it'll still stay under free tier. Go to next step and leave tags as default.
+4. Configure the security group as follows:
+![security group](https://imgur.com/a/zGTCN6F)
+5.  Click next to choose your key pair.(You'll be connecting to SSH via this key so keep it safe, if you don't have one already generate a new one)
+
+Now, we need to attach an Elastic IP to this instance, as instances are allocated only a dynamic IP, also free tier only allows 1 hour of use without  an elastic IP. 
+
+1. Select Elastic IP in the navigation pane, and generate a new Elastic IP.
+2. Associate this Elastic IP to the instance you've just created.
+3. Go to your instance and copy this Elastic IP(you'll see it listed under the v4 IP address)
+
+#### Setting up the EC2 instance
+1. Locate your key.pem file you generated in step 5 and connect to your server by using SSH:
+```
+sudo ssh -i <pem file> ubuntu@<Public IP of the EC2 instance>
+```
+2.  Update your instance
+```sudo apt-get update```
+3.  Install pip
+```sudo apt install python3-pip```
+4.  Install nginx
+`sudo apt-get install nginx`
+5 Install node.js and npm using nvm.
+Get NVM
+``curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash`
+``
+Activate nvm
+`. ~/.nvm/nvm.sh`
+Install node
+`nvm install --lts`
+
+####  Setting up the playground on VM
+1.  Clone the repository
+`git clone https://github.com/fortran-lang/playground.git`
+2.  Assign all read and write permissions to the project directory
+```sudo chmod 777 playground```
+```cd playground```
+3.  Go to frontend directory`cd playground/frontend`, before we build a production version we need to replace our API calls with the public IP.
+	a. Open App.js file which has our API call:
+	`sudo nano playground/frontend/src/App.js`
+	b. Replace the http://127.0.0.1:5000 url with http://{your public ip}:5000
+
+4. Install modules `npm install`, create a build from those modules `npm run build`
+4. Create a directory for the frontend with the following command:
+`sudo mkdir /var/www/html/react`
+Next, copy all contents from the build directory to the react directory:
+`sudo cp -r /home/ubuntu/playground/frontend/build/* /var/www/html/react/`
+
+5.  To go on, set proper ownership of the react directory with the following command:
+`sudo chown -R www-data:www-data /var/www/html/react`
+6. Next, create an Nginx virtual host configuration file to host your React app.
+`nano /etc/nginx/conf.d/react.conf`
+add this to the file:
+`server {
+         listen 80;
+         listen [::]:80;
+         root /var/www/html/react/;
+         index index.html index.htm;
+         # MODIFY SERVER_NAME EXAMPLE
+         location / {
+              try_files $uri $uri/ =404;
+         }
+}`
+7. Restart nginx
+`systemctl restart nginx`
+
+####Setting up Docker
+Refer this link for [setting up docker](https://docs.docker.com/engine/install/ubuntu/#install-using-the-repository "setting up docker") (setup via repository).
+After successfully installing docker switch to the Docker directory `cd playground/backend/docker`
+and build the docker image `sudo docker build -t playground-prod .` .
+
+#### Setting up the backend server
+1.  Go to the backend folder `cd playground/backend`.
+2. Install pipenv to install packages from the pipfile
+  `sudo pip install pipenv`
+3. Make a directory for virtual environment(this will be useful when setting up the service) using `mkdir .venv` and install all required modules using `pipenv install` 
+4. Start the server using:
+```sudo pipenv run gunicorn --bind 0.0.0.0:5000 wsgi:app```
+
+You'll now be able to use the app. You should also setup a service for the gunicorn server so that it starts automatically when the server boots. 
+
+#### Setting up the service
+1. Create a service file for our app `sudo nano /etc/systemd/system/backend.service`
+2. Write the following configuration: 
+```
+[Unit]
+Description=Gunicorn instance to serve backend for playground
+After=network.target
+[Service]
+User=ubuntu
+Group=www-data
+WorkingDirectory=/home/ubuntu/playground/backend
+Environment="PATH=/home/ubuntu/playground/backend/.venv/bin"
+ExecStart=sudo /home/ubuntu/playground/backend/.venv/bin/gunicorn --workers 3 -b :5000 wsgi:app
+[Install]
+WantedBy=multi-user.target
+```
+Press Ctrl + X and save the file.
+3. Start the service using `sudo systemctl start backend`
+4. Then enable it so that it starts at boot:
+  `sudo systemctl enable myproject`
+
+Now, You'll can directly cater requests to the port and your app should work. I recommend using a 
+reverse proxy for your requests by altering the nginx configuration and adding an endpoint
+for the API.
