 Caveats:
 
 - Your container **must** listen to the port 80. Besides no error, the certificate won't be issued if in a different port.
-- The port 2080 is reserved for the certbot
+- The port 2080 is reserved for the certbot and should not be exposed.
 - You cannot set the port 443 for the container with the Letsencrypt. EasyHAProxy will handle this automatically once the certificate is issued. 
 - If you don't run the EasyHAProxy with the parameter `EASYHAPROXY_LETSENCRYPT_EMAIL` no certificate will be issued. 
+- Be aware about the issue limits - https://letsencrypt.org/docs/rate-limits/
 
+## Exposing Ports
+
+- You need to expose at least the ports `80` and `443` when you run the `byjg/easy-haproxy` image. 
+- If you enable the HAProxy statistics you must also expose the port defined in `HAPROXY_STATS_PORT` environment variable. 
+- Every port defined in `easyhaproxy.[definitions].port` also should be enabel. 
+
+e.g.
+
+```bash
+docker run \
+    /* other parameters */
+    -p 80:80 \
+    -p 443:443 \
+    -p 1936:1936 \
+    -d byjg/easy-haproxy
+```
+
+Also, you need to expose these ports in the firewall.
