You’ve defeated the Institute, and now are the hero of the Commonwealth. If you want to pretend you are roleplaying throwing a bunch of tea to the harbor- this would be the ending for you. While this is considered to be the ‘good guy normal’ ending that results in the least amount of karma based decisions and killing factions, it can still lead to a decent climax for your character. This will block all institute locations going forward. With the Institute, you will have to destroy the HQ with the Minutemen.
If you do, then you will have to eliminate the Prydwen with the heavy artillery you receive from the Castle, then defend the said Castle from the Brotherhood when they attempt a full-scale assault in response. While this ending results in the death of the Institute, you also may have to destroy the Brotherhood of Steel as well.
If pledged to the Minutemen, you will no longer be able to complete quests or contact allies of other factions. Often considered one of the better-received endings your men will put you at the front of their army and you decide the other factions fate.
