+## Additional supported formats
+
+JinjaTurtle can also template some common "bespoke" config formats:
+
+- **Postfix main.cf** (`main.cf`) → `--format postfix`
+- **systemd unit files** (`*.service`, `*.socket`, etc.) → `--format systemd`
+
+For ambiguous extensions like `*.conf`, JinjaTurtle uses lightweight content sniffing; you can always force a specific handler via `--format`.
