+Extending the Tool
+------------------
+To extend the tool with a new plugin that already has an HDF5 plugin available, a Python interface is required. Good examples of how filter interfaces look can be found in this `source file <https://github.com/silx-kit/hdf5plugin/blob/main/src/hdf5plugin/_filters.py>`_. In case of developing a new interface, it is advisable to integrate this interface into the `hdf5plugin repository <https://github.com/silx-kit/hdf5plugin>`_, so a wider audience can benefit from it.
 
+Once the Python interface is established, adding the filter definitions to *enstools-encoding* involves minimal additional work, requiring you to extend only a `single file <https://github.com/wavestoweather/enstools-encoding/blob/main/enstools/encoding/definitions.py>`_.
