-`cartesi-rollups-node` pulls in `cartesi-machine-emulator@0.20`, a keg-only build of the emulator
-that the 2.0.0-alpha node series still compiles against. It does not conflict with the current
-`cartesi-machine-emulator` and is not linked into `bin`; the node binaries find it on their own.
+`cartesi-rollups-node` builds against the current `cartesi-machine-emulator` and pulls it in.
 Running the node still needs a PostgreSQL database and an Ethereum JSON-RPC endpoint, configured
 through `CARTESI_*` environment variables as described in the
 [node documentation](https://github.com/cartesi/rollups-node).
