+### Optional: MySQL / MariaDB SSL
+
+You can enable TLS for the MySQL/MariaDB connection with these environment variables:
+
+- DB_MYSQL_SSL: Enable SSL when set to true. If unset or false, SSL disabled (previous default behaviour).
+- DB_MYSQL_SSL_REJECT_UNAUTHORIZED: (default: true) Validate the server certificate chain. Set to false to allow self‑signed/unknown CA.
+- DB_MYSQL_SSL_VERIFY_IDENTITY: (default: true) Performs host name / identity verification.
+
+Enabling SSL using a self-signed cert (not recommended for production).
