Before your infiltration into the Institute, speak with Proctor Ingram. She will task you with stealing data from one of the Institute terminals using a holotape that she gives you. Depending on your work with other factions, you may have already received a similar holotape from a different faction as well.
Locate a terminal near the entrance to the Institute, within the relay area. Access the terminal, and load the Network Scanner holotape. If you are unsure which faction to side with or are curious about each factions’ motives, refer to our guide on determining the best faction in Fallout 4.
Once the data is retrieved from the Institute terminal and loaded onto the holotape, you can complete the rest of Main Quest: Institutionalized if you wish. When you’re ready, leave the Institute and return to Proctor Ingram. Give Ingram the holotape, and she will take it to Proctor Quinlan for decryption. Afterwards, the quest concludes, ensuring your alliance with the Brotherhood of Steel.
