 ## TypeScript Parser
 
-The generation relies heavily the TypeScript Abstract Syntax Tree, and so the code includes ways to parse the source files into a AST representation for easier generation. 
+The generation relies heavily on the TypeScript Abstract Syntax Tree and so the code includes ways to parse the source files into a AST representation for easier generation. 
 
-To do this the code has two supported parser types, .NET and NodeJS, to do realtime parse the code. Using a .NET library it is able to do very quick parsing, but since it has not been maintained it can not handle complex or modern TypeScript syntax.
-But with the NodeJS TypeScript parser it can do modern, more complex TypeScript syntax, but with the trade off of in speed.
