Our new friend is a Runner (for now).
On PC you look at an enemy then press G and the companion will attack. Look close to you and press G, and he will come to you.
To deploy the Companion, check your inventory, and attach it to the weapon wheel or choose deploy. But deploy it outdoors, because it will not always follow you.
Getting the (Good Boy) FOA 5 Armour
To get CSPs (Companion Schematics Points), you need to be in combat and kill enemies together. with your companion. With these points you can buy schematics.

With Armour equipped (shield)
you can’t repair. With the armor equipped the Companion hud gets a shield and shows armour health. When the armour reaches 0%, the hud changes to a Plus-sign
and shows 100% runner health now. When the Plus-sign hud is showing, you can repair your companion with a repair kit.
The option to repair your Companion is greyed out if you don’t have Repair kits in your inventory or you have armour equipped.
When all armour schematics are bought, you will no longer get Armour schematics points. Note: That the free companion only has the first column of Runner Armour.

Earlier than I expected.
What do you think, can we pet our new friend?
Yay, that would be cool.
My comment Is almost copy-pasted, but its not.
I dont like that with any new feature we get a DLC with stuff that should be part of the new feature.
PS: I would like to be able to pet our new friend yes.
I had robot companions in Fallout 4 & they are easy to repair. They do take orders or commands. Sometimes you can add weapons or build them with their own weapons and easy to paint & upgrade. Nice to have I hope in Generation Zero !!
This makes me feel quite nostalgic 🥲
Oh my gosh … has it been three and a half years already? How time flies 
Well… I guess the most important question is, can it get a stick if I throw one ? 
Please devs make it so the homing turret doesn’t kill our friend…
Can we add PVG, missile launchers or homing turrets to our friend?
I don’t think we can add those. The companion has its own arsenal of weapons.
I has a sad now… 
As long as it doesn’t bring us our flares, fireworks and handgrenades back…
Why not? Would be cool to attach unused weapons to a slot. These weapons, like at enemy machines, can be shot off (empties the slot) or it could run out of ammo.
So you would be forced to give him another weapon/stack of ammo.
In my eyes it would be welcome for those many weapons we find in the world or loot.
I am just concluding it has its own arsenal from Carni’s text in Discord: “The weapons you can equip it with are all free.”
It’s all speculation. I could be wrong. 
The companion has behavior modules what kind of behavior would you want to see?
Fetching @Kimosabe_X’s stick, for instance.
Maybe it’s just
God beware…
Hahaha errrrm… actually I’m not sooo sure if I really would want such a module… especially not if the above mentioned behaviour might apply… Like:
“Here doggo… bring it back” *whistles * "come on doggo… " “Ahhh, what i fine boy you are… ehh… what the f…?” *boom *
