I am a graduate student with some background in Galois deformation theory. I am familiar with the basics (the existence of a universal deformation space with prescribed conditions) and with some examples in Galois deformation theory, as well as with the some of the conjectural relations with $p$-adic systems of Hecke eigenvalues (i.e. $R=T$ theorems). I have seen applications and arguments in the case of $\operatorname{GL}_2$.

I'd like to get myself to a spot where I am somewhat familiar with the more modern advancements in the theory, by which I mean, Taylor–Wiles–Kisin patching, Kisin's deformation rings, potential modularity theorems, the Calegari–Geraghty method, the 6-author "Patching and the $p$-adic local Langlands correspondence" paper, etc...

It seems not so easy to start reading such papers without an idea where you're going because frequently they approach 100 pages with many logical dependencies. On the other hand, the more introductory accounts like the Darmon-Diamond-Taylor papers appears to be slightly outdated (as far as I understand).

So, what would be a good roadmap for studying Galois def theory/modularity theorems from a modern perspective? Where should I begin?

Thanks!
