 > Assume the subdomain to be used is websocket.krlan2789.com and the VPS IP is 10.0.27.89
-> 
+>
 1. Add DNS Record for subdomain :
-
-
+
     | Type | Name      | Points to  | TTL   |
     | ---- | --------- | ---------- | ----- |
     | A    | websocket | 10.0.27.89 | 14400 |
 2. Create a certificate for subdomain using certbot :
-    
+
     ```bash
     sudo certbot certonly --webroot -w /root/repositories/WebSocket-Service -d websocket.krlan2789.com
     ```
-    
+
 3. Activate the required module :
-    
+
     ```bash
     sudo a2enmod proxy
     sudo a2enmod proxy_http
     sudo a2enmod proxy_wstunnel
     ```
-    
+
 4. Create Apache config for subdomain :
-    
+
     ```ruby
     <VirtualHost *:80>
     	ServerName websocket.krlan2789.com
-      
+
       Redirect permanent / https://websocket.krlan2789.com
     </VirtualHost>
-    
+
     <IfModule mod_ssl.c>
       <VirtualHost *:443>
         ServerName websocket.krlan2789.com

         ProxyPreserveHost On
         RewriteEngine On

         RewriteCond %{HTTP:Upgrade} =websocket [NC]
         RewriteRule /(.*) ws://localhost:8765/$1 [P,L]

 5. Verify to ensure the Apache config file is correct :
-    
+
     ```bash
     sudo apache2ctl configtest
     ```
-    
+
 6. Enable subdomain Apache config :
-    
+
     ```bash
     sudo a2ensite websocket.krlan2789.com.conf
     ```
-    
+
 7. Restart/reload Apache service :
-    
+
     ```bash
     sudo service apache2 start
-    
+
     *OR*
-    
+
     sudo systemctl reload apache2
     ```
-    
+
 8. Check the Apache service is running without any errors :
-    
+
     ```bash
     systemctl status apache2.service
     ```
-    
+
 9. Run a Node.js app using PM2 to automatically run it when the application crashes until the system reboots/restarts (make sure the system has node and NPM installed beforehand) :
-    
+
     ```bash
     npm i -g pm2
     pm2 start /root/repositories/WebSocket-Service/app.js --name 'Websocket-Service-App'
