-### Expose the API
+#### Using Nginx
 
-This app currently runs on your local network only, we need to expose it so the data consumer on the Data Analysis product can access it and consume the data it provides.
+Nginx is a great reverse-proxy that supports connection polling and real-time connections like Webhook and Server Site Events.

+1. Install & Update Nginx:

 2. Create the config file:

+3. Implement TLS Encryption
+   
+You can use and certificate provided, we'll show you how to use Certbot Setup (Let’s Encrypt TLS) to obtain a free certificate.
+
+Run this after Nginx is live on port 80 (ensure DNS points to your server!):
+
+```bash 
+sudo apt install -y certbot python3-certbot-nginx 
+sudo certbot --nginx -d your_domain.com         # Replace with your domain
+```
+
+Certbot will auto-configure Nginx to use HTTPS and redirect HTTP → HTTPS.
+
+Certificates auto-renew (add a cron job if not existing):
+
+```bash
+sudo certbot renew --dry-run
