In the following table i listed all the MCU films and series in which order i think it should be viewed. I've also added the official MCU tie-ins comics which are a important part of the MCU, closing plotholes and bringing a new perspective to the MCU. Under the heading extra's, I've listed the One-Shots, webisodes and other material of which i think that enriches the MCU.
All the material is listed as it makes chronological the most sense and the most fun to follow. Keeping material as much together, for example; a season is only splitted in mid season or after the whole season. Another example is the Ant-Man prelude, who goes way back into the timeline, but is a lot more fun to read right before the start of the film. This way the viewer stays on the same subject.
For a pure chronological order per episode, film, issue etc. Please see my blog: Donutman's Timeline.
