TITLE: References for Forcing with Side Conditions
QUESTION [5 upvotes]: I'm looking for some good references about Forcing with Side Conditions, including expository papers that explain the main ideas with some details in order to give me a fairly clear insight of those set theoretic problems that are solvable using this approach. Any other reference is also welcome.
