-We also provide a useful tool [pfd-parallel-listnumden-converter](https://github.com/Wu-Zihao/pfd-parallel-listnumden-converter) to convert Mathematica readable files to txt format readable by pfd-parallel (see [format configurations for pfd parallel](#configuration-options-for-pfd_parallel)). 
+Besides, we also provide a useful Mathematica package [PfdParallelM](https://github.com/Wu-Zihao/PfdParallelM) to use pfd-parallel more conveniently in Mathematica UI. Inside this package, there is a component [pfd-parallel-listnumden-converter](https://github.com/Wu-Zihao/pfd-parallel-listnumden-converter) for converting Mathematica readable files to txt format readable by pfd-parallel (see [format configurations for pfd parallel](#configuration-options-for-pfd_parallel)).
