Setting up Netatmo Weather Station

I just purchased my Starter kit, and am trying to get all my birds lined up. Is it better to setup the station from my computer or from the phone, or it doesn’t matter? Where should the indoor unit be placed? Now for the outdoor unit, I understand it must be out of the sun, and away from the rain. So I would like to pose this question. I have a area which is in front of my front door, it is a four foot wide by 5 foot wide overhang with a one foot deep pocket. Can the outdoor module be up in the 4’ by 5’ pocket? The window you partialy see is above the front door.
