+
+## Development Environment
+
+### Ruby and Rails Versions
+- Ruby: 3.4.5 (managed via asdf)
+- Rails: 8.0.3
+- Node: 22.x
+- Bundler: 2.7.2
+
+### Essential Commands
+
+#### Development Server
+```bash
+bin/dev                    # Start Rails server with CSS watching (uses Procfile.dev)
+rails server              # Start Rails server only
+yarn build:css --watch    # Watch and compile CSS changes
+```
+
+#### Database
+```bash
+rails db:create           # Create database
+rails db:migrate          # Run migrations
+rails db:seed             # Seed database with sample data
+rails db:drop             # Drop database (careful!)
+rails db:reset            # Drop, create, migrate, and seed
+```
+
+#### Testing
+```bash
+# Run all RSpec tests
+bundle exec rspec
+
+# Run specific test categories
+bundle exec rspec spec/features
+bundle exec rspec spec/models
+bundle exec rspec spec/requests
+bundle exec rspec spec/integration
+
+# Run Rails tests
+rails test test/models
+rails test test/controllers
+rails test test/integration
+rails test test/system
+
+# Run a single test file
+bundle exec rspec path/to/spec_file.rb
+rails test path/to/test_file.rb
+
+# Run tests with specific line number
+bundle exec rspec path/to/spec_file.rb:42
+```
+
+#### Linting and Code Quality
+```bash
+bundle exec rubocop              # Run Rubocop linter
+bundle exec rubocop -a            # Auto-fix Rubocop offenses
+bundle exec rubocop path/to/file.rb  # Check specific file
+```
+
+#### API Documentation
+```bash
+bundle exec rake rswag            # Generate Swagger/OpenAPI documentation
+# Access at: http://localhost:3000/api-docs/index.html
+```
+
+#### Background Jobs
+```bash
+bundle exec sidekiq              # Start Sidekiq worker
+redis-server                     # Start Redis (required for Sidekiq)
+```
+
+#### Asset Compilation
+```bash
+yarn build:css                   # Build CSS with Bulma
+rails assets:precompile          # Precompile all assets for production
+rails assets:clobber             # Remove compiled assets
+```
+
+## Architecture Overview
+
+### Core Models and Relationships
+
+The application centers around **Member** (User) with Devise authentication:
+- **Member** → has many **Posts** (blog posts)
+- **Post** → has many **Comments** and **Likes**
+- Complex analytics system tracking visitors, browsers, and user interactions
+
+### Authentication & Authorization
+- **Devise** handles authentication with OAuth support (GitHub, Google)
+- **CanCanCan** manages authorization through `app/models/ability.rb`
+- **JWT** tokens for API authentication (`app/models/json_web_token.rb`)
+- API login endpoint: `POST /api/v1/auth/login`
+
+### API Structure
+- Versioned API under `app/controllers/api/v1/`
+- JWT-based authentication for API endpoints
+- Swagger documentation auto-generated from tests
+- API responses use Jbuilder templates in `app/views/api/v1/`
+
+### Real-time Features
+- **Turbo Streams** for live updates without page refresh
+- **Stimulus controllers** in `app/javascript/controllers/`
+- **Action Cable** broadcasts analytics updates to dashboards
+- Chart controller manages real-time analytics visualization
+
+### Background Processing
+- **Sidekiq** jobs in `app/jobs/` process analytics asynchronously
+- Jobs: AddCounterJob, AddBrowserJob, AddUniqueJob, AddLengthJob
+- Redis required for job queue management
+
+### Frontend Stack
+- **Turbo Rails** for SPA-like navigation
+- **Stimulus** for JavaScript behavior
+- **Bulma CSS** framework (compiled via cssbundling-rails)
+- **Chartkick** for analytics charts
+- **Pagy** for pagination
+
+### Testing Approach
+- **RSpec** for API and integration tests (`spec/`)
+- **Rails Test** for models and controllers (`test/`)
+- **Factory Bot** for test data generation
+- **Capybara** with Selenium for system tests
+- Tests generate API documentation via Rswag
+
+### Key Technical Patterns
+
+1. **Counter Caches**: Automatic count maintenance
+   - `posts_count` on Member
+   - `comments_count` and `likes_count` on Post
+
+2. **FriendlyId**: SEO-friendly URLs for members
+   - Uses slug field on Member model
+
+3. **Active Storage**: Avatar uploads with validation
+   - Image processing for variants
+
+4. **Analytics System**:
+   - Visitor tracking with browser fingerprinting
+   - Multiple analytics models for different metrics
+   - MemberBrowser class implements visitor pattern
+
+5. **Broadcasting Pattern**:
+   - CounterAnalytic broadcasts updates to member-specific channels
+   - Real-time dashboard updates via Turbo Streams
+
+### Database Considerations
+- PostgreSQL with multiple extensions enabled
+- Counter caches maintain denormalized counts
+- Indexes on foreign keys and frequently queried fields
+- Bullet gem monitors N+1 queries in development
+
+### Environment Variables
+Required in `.env` for development:
+- `DATABASE_DEV_USERNAME` - PostgreSQL username
+- `DATABASE_DEV_PASSWORD` - PostgreSQL password
+- `GITHUB_ID` & `GITHUB_SECRET` - GitHub OAuth
+- `GOOGLE_ID` & `GOOGLE_SECRET` - Google OAuth
+
+### Deployment
+- Configured for Render.com deployment
+- Dockerfile uses Ruby 3.4.5 and Node 22.x
+- Production uses PostgreSQL and Redis
+- Assets precompiled during Docker build
