You don't need to define participant, but for alignment, you should.
participant User // this will be front
; or
participant "with a2a!@#!$" as A // you can use this like 'A -> User: ***'
; or
participant "new
line" as nl // this will be lastUser->New: message // participant 'New' will defined automatically at here
; or
User-->New: message
; or
User<-A: message
; or
User<--A: message
; or
nl -> nl: " realllly // with multiple lines
looooooong
messageee"
; or
ee <- ee: "
you can't use like this" // when using new line, you should add 1 character to first line at least. I'll fix this soon.- note
- more arrow design
