[Ecriture des rapports] is colored in Coral/Green
[Ecriture des rapports] starts 1 day before [Test du prototype]'s start and ends at [Test du prototype]'s end
@enduml
Everything that starts with simple quote ' is a comment. You can also put comments on several lines using /' to start and '/ to end.
(i.e.: the first character (except space character) of a comment line must be a simple quote ')

[T1] lasts 3 days
/' this comment
is on several lines '/
[T2] starts at [T1]'s end and lasts 1 day
