Includes nginx config snippets for HTTP-to-HTTPS redirects, a reusable shell script for certificate negotiation across multiple domains, and notes on common gotchas like missing directories. The author prefers acme-client over certbot due to its simplicity and minimal dependencies. ## Full article daily.dev links to this article rather than hosting it.
