 ### Parsing
 
 ```ruby
-parser.parse 'Hello Mom!'
-=> true
-parser.parse 'Hello Someone!'
-=> false
+result = parser.parse 'Hello Mom!'
+=> #<HParseResult>
+result = parser.parse 'Hello Someone!'
+=> nil
 ```
 
-Currently you only get `true` or `false` depending on whether the parse succeeded or failed.
-There's no way to access the parsed data yet.
+The `parse` method returns an `HParseResult` object, which needs to be
+kept around until you're entirely done with the parse tree, which can
+be accessed with `result.ast`.
+
+While the AST can be accessed using the same interface as the C
+HParsedToken type, we recommend using `result.ast.unmarshal` instead.
+This converts the entire parse tree into a standalone Ruby-native
+datastructure which will likely be much easier to work with.
