 The simplest way to get started is using the simple fluent API provided with the library. Instantiating a parser is straightforward:
 
 ```java
-NioMultipartParser parser = Multipart.multipart(context).forNio(listener);
+NioMultipartParser parser = Multipart.multipart(context).forNIO(listener);
 ```
 
 The only two mandatory arguments are a multipart *context*, holding information about the current request/response, and a *listener* that will be notified on the progress of the parsing.

 Alternatively the constructors can be used (useful if used along with a dependency injection framework).

 This kind of customization can be used to achieve numerous goals. For example it might be possible to compute the file checksum on fly while data are written to the *StreamStorage*.
