 ## What is Parsing?
 
@@ -19,7 +19,7 @@ First some definitions:
 * **lexer** A algorithm for lexical analysis that separates a stream of text into its component lexemes. Defines the rules for individual words, or set of allowed symbols in a programming language. 
 * **parser** an algorithm for converting the lexemes into valid language grammar. Operates on the level above the lexer, and defines the grammatical rules.

 Most basically, Parsing and Lexing is the process of reading the input text of either the REPL or program and converting that into a format that can be evaluated by the interpreter.
 That converted format, in our case, is `LispVal`. The library we will use for parsing is called `Parsec`.
