Build a bright future underground with the Vault-Tec Workshop. Build a gigantic underground masonry with pre-war technical equipment, nostalgic furniture, lighting and artifacts, and attract people here. And of course, like any good manager, run Vault-Tec-approved experiments on cellar residents to create ideal citizens. Vault-Tec provides the tools you need, the rest is up to you. To activate the Vault Tec Workshop DLC you need to have the current Fallout 4 game on Steam.
