Detailed walkthrough
It is October 23rd, 2102 (2103 as of Wastelanders and 2104 as of Steel Reign). The quest begins after character creation and after the player character has picked up the Pip-Boy next to the door of their room. Waypoints and cardboard cutouts of a Vault Boy will lead the player character through the vault, as the voice of the overseer plays. Items such as food, clothing, and medical items can be collected from various stands lining the path to the exit. Basic gameplay mechanics including the C.A.M.P., hunger, and dehydration are explained along the way, including via interaction with the various Mr. Handy robots located at the stations along the way. Exiting the vault will complete the quest.

Finding the Overseer's log - Vault 76 holotape, which explains where the overseer has gone, is optional. If not collected while still in the vault, the Mr. Handy, Pennington, waiting outside below the vault door will give it to the player character upon speaking with him.
