Summary:
Simply stay away from actions that result in becoming enemies with the Railroad or the Brotherhood of Steel. With the Railroad, I was able to complete main quests up to and including Tradecraft. With the Brotherhood of Steel, I was able to complete main quests up to and including Blind Betrayal. With the Institute, I was able to complete main quests up to and including Mankind - Redefined. Complete these quests before being banished from the Institute. I recommend making a save before being banished. In order to get banished from the Institute, I chose to kill Justin Ayo. An alternate way to get banished is to side with the BOS during Mass Fusion. Spoils of War begins. During the final invasion, ensure that the evacuation order is issued to stay on good terms with the Railroad.

Important Notes:
- I met with the Brotherhood of Steel and the Railroad before discovering the Institute. Recommended.
- Ballistic weave modification can be obtained before or after this ending. Road to Freedom, Tradecraft, and Boston After Dark were completed.
- During The Molecular Level, I built the signal interceptor with the Minutemen (Recommended). If you built it with the Brotherhood of Steel, for example, the holotape with Institute data can be retrieved from Proctor Ingram later on. After being banished from the Institute, speak with Preston to receive Inside Job, which will allow you to speak with Ingram to retrieve the holotape and give it to Sturges.
- After Mankind - Redefined, I recommend raising your relationship level with X6-88 and unlocking his perk before being banished from the Institute.
- Completing Underground Undercover, a Railroad quest, requires working with Father and eventually leads to Mass Fusion. DO NOT complete Mass Fusion. If you have spoken with Allie Filmore, go inform the BOS to begin Spoils of War. You will be banished from the Institute. Complete Blind Betrayal later.
- Magazine on highest floor above cafeteria section of the Institute.
- Remember to get Virgil's FEV serum.
- During final invasion of the Institute, ensure that the evacuation order is issued to stay on good terms with the Railroad.
- If Tactical Thinking has been received, avoid Captain Kells to keep the quest from progressing.
- To receive Defend the Castle, speak with Ronnie Shaw at the Castle after being banished from the Institute. Quest will begin immediately. Form Ranks will need to be completed first if more settlements need to be established.
- Clean Equation is a Railroad side quest that involves taking out a Brotherhood of Steel patrol. I can confirm that completing A Clean Equation won't result in becoming enemies with the BOS. However, if you haven't yet gone back to PAM to complete it and wait 24 hours, approaching the Brotherhood will cause them to turn hostile. As such, ensure that you go back to PAM to complete the quest, and wait 24 hours, before interacting with members of the BOS.
- Complete Covenant quest before completing The Nuclear Option
