If you don’t know about this mod:

A Better World is an upcoming story-driven new world modification for Fallout 4.

A Better World tells the story of two women on the run from the Institute: Jo and Liz, and their mission to create a better, safer world. To support this story, the mod features a dual setting split between the vast wilderness of Abbot County and the derelict ruins of an underground pre-war shopping center called Vault-Tec Plaza.

A new project from the creator of Alton, IL for Fallout 3, A Better World will feature an extensive main quest, plenty of side quests, and a huge new world full of unique activities and challenges.
