Want to start building Outposts and have little to no idea where to start? Well then you're landed on a great find to perhaps help you do just that!
.
To start outposts open up your scanner ('F' default) and then select outpost ('R' default) and you'll see a transparent version of the building above for you to place. Also notice in the upper left of your heads-up display the possible resources you can acquire at this current location.
.
Note: If unable to place an Outpost (option unavailable) it is likely because you are too close to another outpost/point of interest, or that you're on an extreme planet without the required 'Planetary Habitation' skill level.
.
When placing pay attention to the prompts and keybinding hints given... and you can many time adjust the rotation and height of each building/object you place.
.
Caution: some items require you to place them twice.

Okay Fuji, so I get how to place items... and recognize what resources I will get at my location, but what resources should I go after first?
.
Excellent question! As... I asked myself that, to which I painstakingly did some initial research on Outpost Engineering Level 0 buildings to help you gain an understanding what materials you'll need when setting up your outposts.
.
Couple items to note:
1) Requirements are grouped by type and then sorted by the materials used by the most buildings.
2) For simplicity sake, I purposely skipped three categories (Furniture, Decorations, & Displays)

(And yes, I did my best to visually match Starfield color theme and the inorganic materials)
