 HTML SAX Parser for Swift 3
 ======
-**HTMLSAXParser** is a swift module that wraps the libxml2 HTMLParse for the purposes
-of providing a simple lightweight SAX parser for HTML content. SAX parsers provide
-an event based parsing process, where a closure you provide will be called with
-a series of events as the parser moves through the document.
+**HTMLSAXParser** is a swift module that wraps the libxml2 HTMLParser for the purposes
+of providing a simple lightweight SAX parser for HTML content. libxml2 is part of the
+Mac, iOS and Apple TV SDK, if you are developing for those platforms then you will not
+require any additional dependencies. SAX parsers provide an event based parsing process,
+where a closure you provide will be called with a series of events as the parser moves
+through the document.
 
 **HTMLSAXParser** uses enums with associated types for the parsing events and a
 simple of example of usage is: -
 
 ```
 let parser = HTMLSAXParser()
 do {
-	try parser.parse(string: "<html><body>Some HTML Content</body></html>) { event in
+	try parser.parse(string: "<html><body>Some HTML Content</body></html>") { event in
 		switch event {
 			case let .startElement(name, attributes, location):
 				print("Found character : \(name)")
