+| path | path to unix socket | Required |
+| mode | socket file mode | 666 |
+| remove_existing | Whether to remove existing socket file or fail | true |
+
+### Systemd Socket activated fd:
+
+Syntax
+
+ sysd?idx=<fd index>&name=<fd name>&check_pid=<true|false>&unset_env=<true|false>&idle_timeout=<duration>
+
+Only one of `idx` or `name` has to be set
+
+Examples:
+
+ # First (or only) socket fd passed to app
+ sysd?idx=0
+
+ # Socket with FileDescriptorName
+ sysd?name=myapp
+
+ # Using default name and auto shutdown if no requests received in last 30 minutes
+ sysd?name=myapp.socket&idle_timeout=30m
+
+| option | description | default |
+|--------------|--------------------------------------------------------------------------------------------|------------------|
+| name | Name configured via FileDescriptorName or socket file name | Required |
+| idx | FD Index. Actual fd num will be 3 + idx | Required |
+| idle_timeout | time to wait before shutdown. [syntax][0] | no auto shutdown |
+| check_pid | Check process PID matches LISTEN_PID | true |
+| unset_env | Unsets the LISTEN\* environment variables, so they don't get passed to any child processes | true |
+
+### TCP
+
+If the address is not one of above, it is assumed to be tcp and passed to `http.ListenAndServe`.
+
+Examples:
+
+ :http
+ :8888
+ 127.0.0.1:8080
