fine-tuning ru model

Hi
, could you tell me about the further training of the model
https://github.com/alphacep/vosk-api/tree/master/training
Does this interface only provide an opportunity to complete the English model?

Is it possible to install bash run.sh --stage 0 --stop_stage 0

replace in run.sh
data_url=www.openslr.org/resources/31
lm_url=www.openslr.org/resources/11

could you tell me where to find the url for the Russian language?
Thanks!
