+## Remote Control and API
+
+Since version 0.6.0, this filter allows other programs to remotely control it via API. By default the functionality is disabled and can be activated by adding a non-zero DWORD value **RemoteControl** to registry key **HKEY_CURRENT_USER\SOFTWARE\AviSynthFilter**.
+
+For details of the API, please refer to the comments in source file [api.h](https://github.com/CrendKing/avisynth_filter/blob/master/avisynth_filter/src/api.h).

 ## Example script
 
 Add a line of text to videos with less than 20 FPS. Otherwise disconnect the filter.
