+### Extra) How To Secure the pool frontend with Let's Encrypt (https)
+
+First, install the Certbot's Nginx package with apt-get
+
+```
+$ sudo apt-get update
+$ sudo apt-get install python3-certbot-nginx
+```
+
+And then open your nginx setting file, make sure the server name is configured!
+
+```
+$ sudo nano /etc/nginx/sites-available/default
+. . .
+server_name <your-pool-domain>;

+```
+
+Change the _ to your pool domain, and now you can obtain your auto-renewaled ssl certificate for free!
+
+```
+$ sudo certbot --nginx -d <your-pool-domain>
+```
+
+Now you can access your pool's frontend via https! Share your pool link!
