 ## Project Structure & Module Organization
-`create/` contains the Node-based scaffold (`index.js` normalizes CLI options, `main.js` mutates the template). `template/` ships the starter monorepo with workspaces such as `api/` for backend endpoints, `mock-backend/` and `mock-data/` for fixtures, `prototype/` for the prototype app, `ui/` for shared components, and `docs/` for the Antora documentation site. Shared lint and TS configs live in `template/config/`, and bootstrap assets for generated apps sit under `template`.
+`create/` contains the Node-based scaffold (`index.js` normalizes CLI options, `main.js` mutates the template). `template/` ships the default starter monorepo with workspaces such as `api/`, `mocks/`, `msw/`, `prototype/`, `ui/`, and `docs/`. `example-templates/` contains optional independent examples that can be copied into generated projects under `examples/<name>/`. Shared lint and TS configs live in `template/config/`.
 
 ## Build, Test & Development Commands
 Use Node 22+. Run `npm install` at the repo root before touching the CLI. Template work happens inside `template/`: `npm install` for dependencies, `npm run dev` to launch Turbo-powered development, `npm run build` for a production check, `npm run typecheck` for repository-wide TypeScript validation, `npm run test` to execute Vitest suites, and `npm run format` to apply Prettier across Markdown and TypeScript files.
 
 ## Coding Style & Naming Conventions
-Prettier enforces two-space indentation, single quotes, and trailing commas (`npm run format`). Keep imports auto-organized by the Prettier organize-imports plugin. Use `camelCase` for variables and functions, `PascalCase` for React components and types, and kebab-case for file names (e.g., `generate-data.mjs`). ESLint rules from `template/config/eslint/` run in every workspace—resolve warnings or document exceptions in-code.

 ## Testing Guidelines
-Vitest handles unit and integration coverage; colocate specs as `*.test.ts` or `*.spec.ts`. Run `npm run test` for the full suite, or target a package with `npm run test -- --filter=@repo/ui`. Always follow tests with `npm run typecheck` before opening a PR, and extend coverage around generators (`mock-data/cli`) and UI behavior when adding features.

Always follow tests with `npm run typecheck` before opening a PR. When changing the scaffold, cover both the default starter and any affected example templates.
 
 ## Commit & Pull Request Guidelines
 Mirror the existing history by writing concise, imperative subjects (`add build verification for Github`). Group logically related changes per commit. Pull requests must include a summary, testing notes (`npm run build`, `npm run test`, etc.), linked issues when applicable, and screenshots for UI updates.
 
 ## Setup & Configuration Notes
-The scaffold copies `.env.example` to `.env` and swaps `planning-stack-template` tokens; keep those references in sync when editing template assets. Honor the `SKIP_SETUP` and `SKIP_FORMAT` flags in `create/main.js` so automated flows remain consistent. Update every consumer (e.g., `template/gitlab-ci.yml`) when adjusting CI scaffolding.

Honor the `SKIP_SETUP` and `SKIP_FORMAT` flags in `create/main.js` so automated flows remain consistent. Keep example templates independent from the base workspace so they can be deleted safely and are not built automatically by the root Turborepo configuration.

 ## Local testing
 
 To verify the generator before publishing:
 
-1. Run `npm pack` in this repository to produce a tarball (for example `create-tinker-stack-0.2.6.tgz`).
-2. In a temporary directory, execute `npx --yes create-tinker-stack@file://$(pwd)/create-tinker-stack-0.2.6.tgz`.
-    - Replace the path with the absolute path to the tarball from step 1 (npm `create` does not currently support `file:` specifiers).
+1. Run `npm pack` in this repository to produce a tarball (for example `create-tinker-stack-0.2.8.tgz`).
+2. Run the generator from this repository, passing a target directory as a positional argument:
+
+```bash
+npx --yes create-tinker-stack@file://$(pwd)/create-tinker-stack-0.2.8.tgz my-project
+```
+
+This scaffolds a clean starter into `./my-project`.
+
+### With the example bundle
+
+Pass `--with-example` to also generate the `react-router` example, or name a specific example with `--example`:
+
+```bash
+# Default example (react-router)
+npx --yes create-tinker-stack@file://$(pwd)/create-tinker-stack-0.2.8.tgz my-project --with-example
+
+# Named example
+npx --yes create-tinker-stack@file://$(pwd)/create-tinker-stack-0.2.8.tgz my-project --example react-router
+```
+
+The example is placed in `my-project/examples/react-router/` and is independent of the root workspace.
+
+### Notes
+
+- `$(pwd)` must be run from the repository root where the tarball was produced.
+- `npm create` does not currently support `file:` specifiers, so `npx` must be used.
+- Omit the target directory argument to scaffold into the current working directory.

-# Frontend Monorepo for Rapid Prototyping
+# Tinker Stack
 
-This is a npm Template for a Frontend Monorepo. 
+Tinker Stack is a project scaffold for frontend monorepos focused on rapid prototyping.
 
-It puts emphasis on rapid prototyping and a prototype-driven development
-([Pixar Planning](https://www.youtube.com/watch?v=gbuWJ48T0bE&t=1294s)).
+By default it generates a clean starter workspace with:
 
-The prototypes are using a virtual and ephemeral backend, so changes can be made very quickly without any need for
-data migrations on schema changes.
+- a minimal React Router prototype shell
+- shared `api`, `ui`, `msw`, and `mocks` packages
+- Turborepo, TypeScript, ESLint, Prettier, and Antora wiring
+- every example template copied into `examples/<name>/`
 
-Stakeholders can test a fully working UI before a single line of backend code has been written.
+The scaffold no longer ships a demo application in the base workspace.
 
-Test UI concepts on day 1, iterate on them with the designer on day 2 and present them to the customer on day 3.
+## Create a project
 
-The API to the backend has usually had several major iterations before a backend developer even gets involved.
-
-## What is included?
-
-This monorepo contains the following packages/apps:
-
-### Apps and Packages
+```bash
+npm create tinker-stack@latest
+```
 
-- A prototype for the application, based on React Router SPA.
-- A package that provides the domain types and enums that can be shared with the backend.
-- A documentation in [Antora](https://antora.org/) (AsciiDoc) format.
-- A package that provides synthetic data for the applications using
-  [Faker.js](https://fakerjs.dev/).
-- A package that provides a mock API via service workers using [MSW](https://mswjs.io/).
-- A component library that is shared by the main application and the prototype (still empty).
-- ESLint and TypeScript configurations that are shared throughout the monorepo.
+To generate the base workspace without any example folders:
 
-### Features
+```bash
+npm create tinker-stack@latest -- --no-examples
+```
 
-- [TypeScript](https://www.typescriptlang.org/) Monorepo based on ESM standards.
-- Turborepo setup for building and running the monorepo.
-- Code formatting with [Prettier](https://prettier.io/) and linting with
-  [ESLint](https://eslint.org/).
+To generate only specific example templates:
 
-## Documentation
+```bash
+npm create tinker-stack@latest -- --example react-router
+```
 
-The project documentation is written in [AsciiDoc](https://asciidoctor.org/) and is generated using
-[Antora](https://antora.org/).
+By default, all available examples are copied into `examples/<name>/` inside the generated project.
+They are self-contained and can be deleted without affecting the main workspace.
 
-## Getting Started
+## Example templates
 
-To get started, run the following command:
+The generator is designed for multiple named examples. Today the repository includes:
 
-```bash
-npm create tinker-stack@latest
-```
+- `react-router`
 
-This will create a new project based on the Tinker Stack.
+Each example is installed and run separately from its own directory. The root project does not add example folders to its npm workspaces, so Turborepo ignores them by default.
