+* Before starting nginx edit the configuration and change it to your needs. You must change change `server_name` and the paths to the certificates. You can use `nano` (install with `apk add nano` if missing).
+
+```
+server {
+ server_name your.domain;
+ listen 80;
+ ...
+}
+
+server {
+ server_name your.domain;
+ listen 443 ssl http2;
+ ...
+ ssl_trusted_certificate /etc/letsencrypt/live/your.domain/chain.pem;
+ ssl_certificate /etc/letsencrypt/live/your.domain/fullchain.pem;
+ ssl_certificate_key /etc/letsencrypt/live/your.domain/privkey.pem;
+ ...
+}
+```
