You can read Danse's diary on the computer here if you like. Check out the Motor Pool for some extra ammo too. Go inside the police station and load up on ammo and anything else you can loot.

This will kick off the Call To Arms quest, and it's completing this that will result in an invite to join the Brotherhood. Help him out (there's ammo here if you need it) and when he battle is over talk to him. As you arrive you'll see Brother Danse in power armor fighting off a whole bunch of ghouls and a super mutant. You'll hear a distress call asking for help, which will mark the Cambridge Police Station on your map. If you haven't started The First Step, head over to here on your world map: It's around here you'll pick up the Military Frequency AF95 radio signal. Head over to the plant, and circle around the building. You don't need to complete the quest at this stage. Not least because once you do you get handed a tasty customised laser rifle.ДЇirstly, make sure you have started The First Step quest, which marks the Corvega Assembly Plant on your map. They are the do-gooders, and you'll probably want to join them as soon as possible. The Brotherhood of Steel is the most iconic group in the Fallout universe, striding around in Power Armor and protecting the Commonwealth. If you want to get in with the Brotherhood of Steel - either in the original Fallout 4, or in the new VR version - we're here to help. You've got the iconic power armor, but you really need to be part of the Brotherhood of Steel.
