How to add a label under a rectangle?

Question

Hi

I have the simple script below:

rectangle Gateway [
        Gateway
]
i want to put a label "API A+B+C"  right under the rectangle, centred. This should be obvious but i am just starting and dont know how./

Thanks

Hello A.,

In fact it is not easy to add label `under the rectangle`, because the objects can be linked on us...

Here are some examples, but inside the rectangle...

@startuml
rectangle Gateway <<API A+B+C>>

rectangle G [
Gateway
API A+B+C
]

database db
G --> db
@enduml

If that can help,
Regards.
