What's resource depot and gathering post actually do ?

[Delicia Suprema]

as far i can tell. Gathering post makes my minions grab any resources and put them there. But resource depot ? I have first to choose which resource i want for it and then what ? I put it close to the coal mining ?

They increase your maximum storage of that resource. No need to put them anywhere special (just put them on the border).
And gathering posts help gathering by providing warmth and I think speed bonuses

You can put the resource depot anywhere, it just expands your storage capacity for whatever resource you choose to assign to it.

The gathering post allows you to gather faster with fewer people plus it gives a +1 to heat over gathering from a pile directly and you get the heater option on them once you research heaters. When you place it, you will see a shaded circle around it, that is the gather area. Make sure whatever you want the workers in it to gather is in the shaded area (ie. individual resource piles or the front area of the coal thumpers where the coal piles up). If you have multiple resources piles in the shaded area the workers will gather from all the piles.

People gather faster in gathering posts and you need them when temperature drops to -30 and under to reduce chance of getting sick
The depots will be needed in the late game to stock ressources before the storm. They dont require heat. You can place them far to not take heated space.
