How to use evofr

Dear nextstrain team, I’ve successfully installed evofr, but I don’t find ways to use the evofr to forecasts SARS-CoV-2.
I also can’t import my own data.

I would appreciate it if you could provide us with more details!

You can find some sample usage in this repo: GitHub - nextstrain/forecasts-ncov: SARS-CoV-2 variant growth rates and frequency forecasts

Thank you very much for your reply.
I have found these two scripts, but I still don’t understand how to use them. For example, where should I input the path of my own metadata and what is the format requirement for the input file? Could you please provide a more detailed explanation?

And if I conducted this Usage:
nextstrain build . --configfile config/config.yaml --config data_provenances=gisaid variant_classification=nextstrain_clades geo_resolutions=global
Do I need to change any parameters?
