+Most of the design of `slox` is fairly similar to the one in the book. There are four phases involved in the execution of code in `slox`:
 
 - scanning for tokens
 - parsing of tokens into statements and expressions
 - resolving of variables from parsed code
 - interpreting of resolved statements 
 
-Both the REPL and file runner instantiate the scanner, parser, resolver, and interpreter in succession, each feeding their results to the next, and eventually printing the output of the interpreter.
+However, unlike how they are implemented in the book, the REPL and file runner instantiate just the interpreter, passing in code to be executed; it is the interpreter that instantiates and runs each of the scanner, parser, resolver in succession, each feeding their results to the next. The interpreter also reads in a small standard library defined in a string; at this point, only a class declaration for a `List` class and some associated methods are defined in it.
 
-Nonetheless, there are a few differences between this implementation and that in the book.
