Details on installing aluminum siding?

Hi,
In few days I'm going to order the aluminum for my teardrop. Does anyone have detail pictures (or schematics) on how to install the aluminum and molding?
Also I'll be interested to see some hatches and how are they installed (I still have to make mine) and how to make the hatch as water proof as possible.
I saw this schematic (the top one). Is this the kind of molding should I get or right angle profile?

Thank you!
