 ### Main results
-    - [BigStep](./BigStep.v) covers section 2-3, culminating in Theorem 1: `concrete_symbolic_correspondence`
-    - [SmallStep](./SmallStep.v) defines and describes the small-step trace semantics of section 4, and
-    - [Correspondence](./Correspondence.v) proves Theorem 2: `big_small_correspondence`
-    - [Direct](./Direct.v) proves Proposition 1 (`trace_if_direct` and `direct_if_trace`) and its corollaries `correctness` and `completeness`.

 ### Auxilliary materials
-    - [Expr](./Expr.v) contains the syntax of expressions, and
-    - [Syntax](./Syntax.v) the syntax of our toy language WHILE
-    - [Maps](./Maps.v) contains definitions and useful lemmas about total maps used to reason about substitutions and valuations
-    - [Limits](./Limits.v) contains the use of constructive description to handle non-termination
-    - Finally, [BigStepExamples](./BigStepExamples.v) contains some examples runs of the big step semantics
