 tregex is a wrapper around Python regular expressions that makes usage smoother and more user friendly.
+
+* <b>to_dict(pattern, string)</b>: Takes a pattern with named capture groups and returns a dictionary.
+
+* <b>to_object(pattern, string)</b>: Takes a pattern with named capture groups and returns a generic class with named groups as properties (future: DataClass in python 3.7).
+
+If the user has a pattern with named groups, but only wants a simple match, <b>find</b> will only return the matched string. If the user has a pattern with named groups, but only wants group match, <b>group</b> will only return the grouped tuples.
+
+<b>similarity</b>: Takes two strings and returns a score based on how similar the two strings are. Uses difflib.
