 and usability in writing C extensions.
 
 
-dxfeed library already contains basic C-API functions and convenient access to them via wrapper classes.
-For now, the package covers the core C-API functionality, for example, creating connections and subscriptions,
-receiving data, etc.
+The design of the dxfeed package allows users to write any logic related to events in python as well as
+extending lower level Cython functionality. Moreover, one may start working with the API using the default
+values like function arguments or a default event handler.
 
-Moreover, default listeners (functions responsible for event processing) are ready to use. The user may also
-write his custom listener in Cython. The instructions are here: :ref:`custom_listener`.
+On this website, you will find dxfeed usage examples and docstrings to each function, class,
+and its methods and fields.
 
-At this website, you will find information about the functionality of the library, how to write your custom listener,
-documentation to all available functions, and information for developers.
