I think the provisional government stuff should be in that question. You should probably also:
-Talk about power of Soviets (controlled railway, army etc)
-July Day Crisis (Kronstadt Sailors randomly attempt an uprising and fail, and then Kornilov does the same thing
-Why bolshevik policies of ending the war and land distribution were popular
-How lenin and trotters went around to factories talking to the workers and telling them how good communism is
-Russia is getting its butt kicked in WWI
and then how the Bolsheviks walked into government cause nobody could be bothered to stop them
Im sure there's stuff ive missed that others will help you with
