+## Completed Setup Tasks
+
+### 1. Go Module Initialization
+- ✅ Initialized Go module: `github.com/user/custom-start-page`
+- ✅ Go version: 1.26.0 (installed at `/usr/local/go/bin/go`)
+
+### 2. Directory Structure

+```
+
+### 3. Configuration Management
+- ✅ Created `pkg/config/config.go` with environment variable support
+- ✅ Configuration for:
+  - Server (host, port)
+  - Database (DynamoDB endpoint, region, table prefix)
+  - OAuth (Google client ID/secret, redirect URL)
+  - Session (secret key, max age)
+- ✅ Comprehensive unit tests for configuration loading
+
+### 4. DynamoDB Local Setup
+- ✅ Created `docker-compose.yml` for DynamoDB Local
+- ✅ Configured to run on port 8000
+- ✅ Persistent volume for data storage
+- ✅ Make commands for easy management:
+  - `make db-start` - Start DynamoDB Local
+  - `make db-stop` - Stop DynamoDB Local
+  - `make db-reset` - Reset DynamoDB Local data
+
+### 5. Testing Framework
+- ✅ Installed gopter (v0.2.11) for property-based testing
+- ✅ Created test helpers in `internal/testing/helpers.go`
+- ✅ Property test configuration with customizable parameters:
+  - MinSuccessfulTests: 100 (default)
+  - MaxSize: 100 (default)
+  - Workers: 4 (default)
+- ✅ Comprehensive tests for test helpers
+- ✅ All tests passing
+
+### 6. HTML Templates with HTMX
+- ✅ Base layout template (`templates/layouts/base.html`) with:
+  - HTMX 1.9.10
+  - Tailwind CSS (CDN)
+  - Sortable.js for drag-and-drop
+  - Prism.js for syntax highlighting (JavaScript, Python, Go)
+- ✅ Login page template with OAuth provider buttons
+- ✅ Dashboard template with:
+  - Top toolbar (search bar, page tabs, user menu)
+  - Widget grid with HTMX integration
+  - Sortable initialization for drag-and-drop
+
+### 7. CSS Framework
+- ✅ Tailwind CSS via CDN
+- ✅ Custom CSS in `static/css/main.css`:
+  - Widget styles
+  - HTMX transition effects
+  - Tag styles
+  - Bookmark styles
+  - Notes editor styles
+  - Loading indicators
+  - Toast notifications
+  - Form styles
+  - Button styles
+
+### 8. JavaScript Setup
+- ✅ Created `static/js/main.js` with:
+  - Toast notification system
+  - HTMX event listeners for user feedback
+  - Prism.js integration for code highlighting
+  - Debounce helper for auto-save
+  - Search form validation
+  - Tag autocomplete helper
+  - Format selector for notes
+  - Confirm delete actions
+
+### 9. Environment Variables
+- ✅ Created `.env.example` with all required variables
+- ✅ Configuration validation in code
+- ✅ Sensible defaults for development
+
+### 10. Development Tools
+- ✅ Makefile with commands:
+  - `make help` - Show available commands
+  - `make build` - Build the application
+  - `make run` - Run the application
+  - `make test` - Run all tests
+  - `make test-coverage` - Run tests with coverage
+  - `make dev` - Start development environment
+  - `make db-start/stop/reset` - Manage DynamoDB Local
+  - `make deps` - Download dependencies
+  - `make fmt` - Format code
+  - `make clean` - Clean build artifacts
+
+### 11. Documentation
+- ✅ Comprehensive README.md
+- ✅ .gitignore for Go projects
+- ✅ This SETUP.md summary
+
+### 12. Build Verification
+- ✅ Application builds successfully
+- ✅ Binary created: `bin/server` (7.7MB)
+- ✅ All tests passing (config + testing helpers)
+
+## Test Results
+
+```
+✅ pkg/config tests: 9/9 passed
+✅ internal/testing tests: 3/3 passed
+✅ Build: successful
+```
+
+## Next Steps
+
+The infrastructure is now ready for implementing the application features:
+
+1. **Task 2**: Implement authentication system
+   - User data model and DynamoDB table
+   - OAuth service with Google provider
+   - Session management
+   - Login and dashboard templates
+
+2. **Task 3**: Implement core data models and DynamoDB integration
+   - Storage service wrapper
+   - All data models (Page, Widget, Bookmark, Note, etc.)
+   - DynamoDB table schemas
+
+3. **Task 4+**: Continue with page management, widgets, tags, etc.
+
+## Dependencies Installed
+
+- `github.com/leanovate/gopter` v0.2.11 - Property-based testing
+
+## Environment Setup Required
+
+Before running the application, you need to:
+
+1. Copy `.env.example` to `.env`
+2. Add your Google OAuth credentials:
+   - `GOOGLE_CLIENT_ID`
+   - `GOOGLE_CLIENT_SECRET`
+3. Start DynamoDB Local: `make db-start`
+4. Run the application: `make dev`
+
+## Notes
+
+- Go binary path: `/usr/local/go/bin/go`
+- DynamoDB Local endpoint: `http://localhost:8000`
+- Server will run on: `http://localhost:8080`
+- All configuration is environment-based (12-factor app)
+- Testing framework supports both unit and property-based tests
