-# ast:%make-lambda
-    (ast:%make-lambda lambda-id args body)
+Create an instance of the `ast-lambda` record type. 
+
+This data type is at the center of this module and consists of the following data:
+
+* `id` - Unique numeric ID assigned to each lambda
+* `args` - Arguments to the lambda. This may be one of:
+     * symbol indicating a function takes any number of arguments
+     * list of symbols corresponding to each of a fixed number of arguments to the function
+     * improper list indicating a function taking a fixed number of required arguments as well as an arbitrary number of optional arguments
+* `body` - Expression in the function body of the lambda
+* `cont` - Boolean indicating whether the lambda has a continuation
+
+`ast:make-lambda` automatically assigns the `id` field to a unique value.
 
 # ast:lambda?
     (ast:lambda? obj)
 
+Predicate indicating whether `obj` is an `ast-lambda` object.
+
 # ast:lambda-id
 
     (ast:lambda-id lambda-obj)
 
+Return the `id` field of the given `ast-lambda` object.
+
 # ast:lambda-args 
 
     (ast:lambda-args lambda-obj)
 
+Return the `args` field of the given `ast-lambda` object.
+
 # ast:set-lambda-args!
 
     (ast:set-lambda-args! lambda-obj args)
 
+Change the `args` field of the given `ast-lambda` object.
+
 # ast:lambda-body 
 
     (ast:lambda-body lambda-obj)
 
+Return the `body` field of the given `ast-lambda` object.
+
 # ast:set-lambda-body!
 
     (ast:set-lambda-body! lambda-obj body)
 
+Change the `body` field of the given `ast-lambda` object.
+
 # ast:ast->sexp
 
     (ast:ast->sexp exp)
 
+Convert an abstract syntax tree `exp` back into an equivalent expression consisting of standard Scheme S-expressions. IE: `lambda` forms instead of `ast-lambda` objects.
+
 # ast:sexp->ast
 
     (ast:sexp->ast exp)
 
+Convert a standard Scheme S-expression tree containing `lambda` forms into an equivalent abstract syntax tree consisting of equivalent `ast-lambda` objects.
+
 # ast:ast->pp-sexp
 
     (ast:ast->pp-sexp exp)
 
+Transform an abstract syntax tree into one that prints more cleanly.
