 ```sh
 git clone https://github.com/tidalcycles/strudel.git && cd strudel
-npm i # install at root to symlink packages
-npx lerna bootstrap # install all dependencies in packages
-cd repl && npm i # install repl dependencies
-npm run start # start repl

 ## Package Workflow
 
 The project is split into multiple [packages](https://github.com/tidalcycles/strudel/tree/main/packages) with independent versioning.
-When you run `npm i` on the root folder, [npm workspaces](https://docs.npmjs.com/cli/v7/using-npm/workspaces) will symlink all packages
-in the `node_modules` folder. This will allow any js file to import `@strudel.cycles/<package-name>` to get the local version,

 ### New Packages
 
 To add a new package, you have to publish it manually the first time, using:
 
 ```sh
-cd packages/<package-name> && npm publish --access public
+cd packages/<package-name> && pnpm publish --access public
