Everybody who catches a fleeting glimpse of Woodin's central papers on Ultimate $L$ (i.e. Suitable Extender Models I & II), admits that they aren't so tempting for lazy readers who don't like to deal with a lot of technicalities in their very first approach towards such an important topic.
On the other hand there are a lot of lazy but curious readers (like me) out there who seek royal roads leading to the main ideas of such long technical papers; the descriptive articles explaining the history, philosophy and general ideas behind the proofs and related conjectures (e.g. $HOD$ conjecture).
In this direction a simple Googling brings up several related articles and blog posts as well as uncountablly many lecture slide shows (mainly by Woodin himself) including the followings:
Caicedo's "Luminy – Hugh Woodin: Ultimate L" on his website.
This question is intended to provide a list of descriptive articles on Woodin's Ultimate $L$ project. Please let me know if you are aware of any related under preparation article too.
