   Copy the tweets.csv file from your local machine to the VPS.

   scp -i "secret.pem" path/tweets.csv ubuntu@publicip:github/twitter-sentiments/twitter-api

   If you encounter a permission denied error, use the following command on the VPS:

   sudo chmod 777 (remote folder)

3. Navigate to the project directory

cd twitter-sentiments

4. Start Docker

docker compose up -d

5. Set up Nginx

apt update
apt install nginx
vim /etc/nginx/conf.d/samarthasthan.conf
