 #### NGINX
 
 To expose our services in the server we need to configure a reverse proxy server. For this we will use nginx web server with ssl certificates for enabling https protocol.
 
 To get started, we need to install:
 
 ```
-# apt install nginx certbot
+apt install nginx certbot
 ```
 
 Enable nginx service
 
 ```
-# systemctl enable nginx.service
-# systemctl start nginx.service
+systemctl enable nginx.service
+systemctl start nginx.service
 ```
