Just you're average citizen, trying to keep up with the overwhleming timeline that is Marvel...
I've put them in release-date chronological order to the best of my ability. For reference for those who do follow the press junkets, the Phases were d as:
Phase 1 - 2008-2012 (aka Avengers Assembled)
Phase 2 - 2013-2015
Phase 3 - 2016-2019
Phase 4 - 2020-2022
Phase 5 - 2023 onward

Yes I did include the Hulk films because they had end-credit scenes that led to Iron Man.

I'll continue revising this for as long as they make the MCU I guess.
