No description provided.

@xlc I was able to make it run, but it needs some documentation also around how to use it as tools like polkadotJs can't be used with it.

I also tried to run it and got:

Thanks for remind me to have more docs.
run-block only replay a single block and that's it. It should log all he storage changes from that block and you can see we need to tweak the log output format.

yarn start or yarn dev will run the test node. Defaulting to fork on the latest block of the selected endpoint. And then you can connect to via localhost:8000 from polkadot apps and start submitting transactions.
