+For Yarn Classic (1.x), use npm to run the tagged creator and select Yarn for installation:
+
+```sh
+npm create @legendapp/spark@next MyApp -- --package-manager yarn
 ```
 
 To choose a package manager, pass `--package-manager npm|pnpm|yarn|bun`. For example:
 
 ```sh
-npm create @legendapp/spark@latest MyApp -- --package-manager pnpm
+npm create @legendapp/spark@next MyApp -- --package-manager pnpm
 ```
 
 The chosen manager must be installed. The commands below use npm; use your chosen manager's `run` command instead if needed. Keep the generated lockfile and `spark-packages/` archives in version control so other machines can reinstall the same inputs.
