Projects with multiple cpp2 files

[AdRiley]

Sorry this is a newbie question, but what is the correct way of splitting a project across multiple .cpp2 files?

Say I have this code

main: () =
{
Hello();
}

Hello : () =
{
std::cout << "Hello World";
}

And want to move the definition of Hello into a different file?
