During Wayward Souls, accept the job from Duchess to receive the overseer's holotape. Listen to the holotape and follow the road to Flatwoods. Once there, register as a Volunteer to finish the quest.
A robot named Pennington was waiting outside of Vault 76 -- it might know where the Overseer went, or what is happening in Appalachia.

Find the Overseer's C.A.M.P.
The Overseer set up a C.A.M.P. south of the Vault. If I follow the road, I can probably locate it. Would be logical to set it up near the river, so I should head towards that intersection.
The Overseer moved on to a town called Flatwoods. Thankfully she left me with some supplies, including a C.A.M.P. of my own. If I follow the road and head south, I should find her there.

(Optional) Tune Pip-Boy radio to the Responders' Signal
The Overseer was here, that's for sure. Found another one of her holotapes in the Flatwoods Church. Looks like this place is deserted.

Register as a Volunteer
The Overseer recommended I become a Volunteer for the Responders to get some basic training. They may be gone, but they did know how to live for a while. I should see what I can discover in their old systems.

After leaving Vault 76, I set out for the nearby town of Flatwoods to look for the Overseer. I found evidence of a group called the Responders that was helping the people in the region to survive, and I registered as a Volunteer to access their systems.
