+### Advanced Usage
+
+#### KawazuConverter Class
+
+Method “**Convert**” accepts six parameters, the last five of which are optional. The **first** parameter is the original Japanese string, the **second** one is the target form of the sentence, the **third** one is the presentation method of the result, the **forth** one is the writing systems of romaji and the **last two** are delimiters. It will return the result string as a async task.
+
+Method “**GetDivisions**” accepts exactly the same six parameters as “Convert”, but returns the raw result from the word Separator.
+
+#### Division Class
+
+Represents the division from the word separator.
 
+#### JapaneseElement Class
+
+A single reading element in a Japanese sentence.
+For example, in sentence "今日の映画は面白かった。"
+"今日","の","映画","は","面白","か","っ","た" are all JapaneseElement in this condition.
+For each of them represents a unit of pronunciation.
+
+#### Utilities Class
+
+Provides several useful Japanese utilities.
+
+### Typical Usage
