-# Apache<sup>&reg;</sup> DataSketches&trade; Core Java Library Component
 This is the core Java component of the DataSketches library.  It contains all of the sketching algorithms and can be accessed directly from user applications. 
 
 This component is also a dependency of other components of the library that create adaptors for target systems, such as the [Apache Pig adaptor](https://github.com/apache/datasketches-pig), the [Apache Hive adaptor](https://github.com/apache/datasketches-hive), and others.
 
-Note that we have parallel core library components for C++, Python and GO implementations of many of the same sketch algorithms:
