+# Quick Start Guide
+
+This guide will help you get the MSW + React CRUD example up and running in 5 minutes.
+
+## Prerequisites
+
+- Node.js 18 or later
+- pnpm package manager
+
+## Step 1: Install Dependencies
+
+From the repository root:
+
+```bash
+pnpm install
+```
+
+This will install all dependencies for the monorepo, including this example.
+
+## Step 2: Build Required Packages
+
+Build the core packages that the example depends on:
+
+```bash
+# Build the spec package (contains type definitions)
+pnpm --filter @objectstack/spec build
+
+# Build the client package
+pnpm --filter @objectstack/client build
+```
+
+## Step 3: Initialize MSW
+
+The MSW service worker file should already be initialized, but if you need to regenerate it:
+
+```bash
+cd examples/ui/msw-react-crud
+npx msw init public/ --save
+```
+
+## Step 4: Start the Development Server
+
+```bash
+cd examples/ui/msw-react-crud
+pnpm dev
+```
+
+The application will start on `http://localhost:3000`
+
+## Step 5: Test CRUD Operations
+
+Once the app is running, you can:
+
+1. **Create** a new task using the form
+2. **Read** tasks in the task list
+3. **Update** a task by clicking "Edit"
+4. **Delete** a task by clicking "Delete"
+5. **Toggle completion** status by checking/unchecking the checkbox
+
+## What's Happening Under the Hood?
+
+When you interact with the application:
+
+1. React components call `@objectstack/client` methods (e.g., `client.data.create()`)
+2. The client makes HTTP requests to `/api/v1/data/task`
+3. MSW intercepts these requests in the browser
+4. Mock handlers return data from an in-memory database
+5. The UI updates with the response
+
+All network requests visible in DevTools are real HTTP requests - they're just being intercepted and handled by MSW!
+
+## Troubleshooting
+
+**Problem**: MSW worker not starting
+**Solution**: Run `npx msw init public/ --save` again
+
+**Problem**: TypeScript errors during build
+**Solution**: Make sure you've built the dependency packages first
+
+**Problem**: 404 errors in browser
+**Solution**: Check that the MSW worker is registered (look for console message)
+
+## Next Steps
+
+- Modify `src/mocks/browser.ts` to add more fields or objects
+- Customize the UI in `src/App.css`
+- Add more complex query operations
+- Experiment with filters and sorting
