-## Migrating from the Node CLI
-
-The Steel CLI is now a single native Rust binary. If you previously installed it via `npm i -g @steel-dev/cli`, the `install.sh` script auto-detects and removes the old Node-based install. You can also do it manually:
-
-```bash
-npm update -g @steel-dev/cli    # auto-installs native binary
-npm uninstall -g @steel-dev/cli # optional cleanup
-export PATH="$HOME/.steel/bin:$PATH"
-```
