-This folder contains a script to run with `tsx` together with `retesteth`.
-
-# Instructions
-
-Clone `ethereum/tests` (either in the `ethereumjs-monorepo` or elsewhere).
-
-Configure and run `transition-tool`:
-
-Note: All paths are relative paths to the `VM` package root.
-
-1. If you change the port number in `transition-cluster.ts` to anything other than 3000 (or run `transition-cluster` on a separate machine or different IP address from retesteth), update `test/vm/retesteth/clients/ethereumjs/start.sh` to reflect the right IP and port.
-
-2. From VM package root directory, run `tsx test/retesteth/transition-cluster.cts`. (Note: if not ran from root, spawning child processes will error out!)
-
-Configure and run `retesteth`:
-
-1. Follow the build instructions to build and install [`retesteth`](https://github.com/ethereum/retesteth)
-
-2. Run `retesteth` from `[retesteth repository root]/retesteth` using the below command
-
-`./retesteth -t GeneralStateTests -- --testpath $ETHEREUM_TESTPATH --datadir $RETESTETH_CLIENTS --clients "ethereumjs"`
-
-Here `$ETHEREUM_TESTPATH` should be set to where `ethereum/tests` root folder is installed (so after cloning it). `$RETESTETH_CLIENTS` should be set to `[ethereumjs-monorepo root]/packages/vm/test/retesteth/clients` (use the absolute path from root when running retesteth from another folder).
-
-Note: if an error regarding "default client not found" pops up, copy the `test/retesteth/clients/ethereumjs` folder into `test/retesteth/clients/default`. If retesteth complains about Paris missing, then move genesis/Merge.json to genesis/Paris.json
