 ## Key Organizational Principles
 
-### ✅ **Feature-Based Organization**
+### ✅ **Feature-Based Component Organization**
+
+Components are organized by functionality rather than by type:
+
+```
+components/
+├── medication/     # All medication-related UI
+├── auth/          # Authentication components
+├── admin/         # Admin interface
+├── modals/        # Modal dialogs
+└── ui/            # Reusable UI components
+```
+
+**Benefits:**
+
+- Related functionality stays together
+- Easy to find and modify features
+- Clear boundaries between different parts of the app
+- Scalable as features grow
+
+### ✅ **Service Layer Architecture**
+
+Services provide business logic separate from UI components:
+
+```
+services/
+├── database/      # Data persistence with strategy pattern
+├── logging/       # Centralized logging system
+└── auth/          # Authentication and user management
+```
+
+**Benefits:**
 
-- Components grouped by functionality (medication, auth, admin, etc.)
 - Clear separation of concerns
-- Easy to locate related files
-
-### ✅ **Script Centralization**
-
-- All deployment and utility scripts in `/scripts/`
-- Consistent naming conventions
-- Easy access via npm/bun scripts
-
-### ✅ **Testing Structure**
-
-- Unit tests alongside source code (`services/auth/__tests__/`)
-- Integration tests in `/tests/integration/`
-- E2E tests with Playwright in `/tests/e2e/`
-- Manual debugging tools in `/tests/manual/`
-- Comprehensive test documentation
-- TypeScript support with temporary type declarations
-
-### ✅ **Documentation Organization**
-
-- Feature-specific READMEs in relevant folders
-- Centralized docs in `/docs/` folder
-- Clear architectural documentation
+- Reusable business logic
+- Easy to test and mock
+- Strategy pattern allows flexible implementations
 
 ### ✅ **Configuration Management**
 
-- Environment files at root level
-- Build configurations easily accessible
-- Docker and K8s configs clearly separated
+Centralized configuration with environment-based templates:
 
-## Benefits
+```
+config/
+└── unified.config.ts    # Single source of truth
 
-🎯 **Maintainability** - Clear structure makes code easy to maintain  
-🔍 **Discoverability** - Logical organization helps find files quickly  
-🧪 **Testability** - Well-organized test structure  
-📦 **Deployability** - Scripts and configs clearly separated  
+# Template approach
+index.html.template → index.html    # Processed with environment variables
+.env.example → .env                 # User customization
+```
+
+**Benefits:**
+
+- No hardcoded configuration
+- Environment-specific settings
+- Type-safe configuration access
+- Clear separation of config and code
+
+### ✅ **Testing Strategy**
+
+Comprehensive testing at multiple levels:
+
+```
+tests/
+├── integration/   # Service integration tests
+├── manual/        # Debug scripts and manual testing
+└── e2e/          # Full application testing
+
+# Unit tests alongside code
+services/auth/__tests__/   # Co-located with services
+components/__tests__/      # Component-specific tests
+```
+
+**Benefits:**
+
+- Tests close to the code they test
+- Multiple testing strategies
+- Easy to run specific test suites
+- Clear separation of test types
+
+### ✅ **Documentation Structure**
+
+Documentation organized by purpose and audience:
+
+```
+docs/
+├── architecture/    # System design and patterns
+├── setup/          # Configuration and installation
+├── development/    # Developer guides and APIs
+└── implementation/ # Current status and features
+```
+
+**Benefits:**
+
+- Easy navigation by role (developer, ops, etc.)
+- Clear separation of different doc types
+- Comprehensive coverage of all aspects
+- Living documentation that stays current
+
+## 🎯 Development Workflow
+
+### Local Development Setup
+
+1. **Environment Configuration**
+
+   ```bash
+   cp .env.example .env    # Copy template
+   nano .env               # Customize settings
+   ```
+
+2. **Template Processing**
+
+   ```bash
+   bun run predev         # Process HTML templates
+   bun run dev            # Start development server
+   ```
+
+3. **Code Quality**
+   ```bash
+   bun run lint           # Check code quality
+   bun run format         # Format code
+   bun run type-check     # TypeScript validation
+   ```
+
+### Database Strategy Selection
+
+The application automatically selects the appropriate database strategy:
+
+- **Development**: Mock database (instant responses, no setup)
+- **Testing**: Mock database (isolated test data)
+- **Production**: CouchDB (persistent storage)
+
+### Component Development
+
+1. **Create feature-based components** in appropriate folders
+2. **Export from index.ts** for clean imports
+3. **Co-locate tests** with components when appropriate
+4. **Use TypeScript** for type safety
+
+### Service Development
+
+1. **Implement business logic** in service layer
+2. **Use dependency injection** for testability
+3. **Follow strategy pattern** for flexibility
+4. **Add comprehensive tests** for reliability
+
+## 📊 Metrics and Standards
+
+### Code Organization
+
+- **Feature cohesion**: Related code stays together
+- **Clear boundaries**: Services, components, utilities clearly separated
+- **Consistent patterns**: Similar organization across features
+- **Scalable structure**: Easy to add new features without reorganization
+
+### Development Experience
+
+- **Fast setup**: One command to get started
+- **Quick iteration**: Hot reloading and instant feedback
+- **Easy testing**: Multiple test strategies available
+- **Clear debugging**: Structured logging and debug tools
+
+### Maintainability
+
+- **Self-documenting**: Clear folder structure and naming

-# 🎯 Template-Based Kubernetes Configuration
+# 🎯 Template-Based Configuration Approach
 
 ## Overview
 
-We've implemented a **template-based approach** using environment variables instead of manual base64 encoding for Kubernetes secrets. This is much more user-friendly and secure.
+RxMinder uses a **template-based configuration approach** with environment variables to provide flexible, secure, and maintainable configuration management across different environments.
 
-## 🆚 Before vs After Comparison
+## 🆚 Configuration Philosophy
 
-### ❌ Before (Manual Base64 Encoding)
+### ❌ Before (Hardcoded Values)
 
-**Old approach required manual base64 encoding:**
+**Old approach with hardcoded configuration:**
 
-```yaml
-# k8s/couchdb-secret.yaml
-apiVersion: v1
-kind: Secret
-data:
-  # User had to manually encode:
-  # echo -n "admin" | base64        -> YWRtaW4=
-  # echo -n "password" | base64     -> cGFzc3dvcmQ=
-  username: YWRtaW4=
-  password: cGFzc3dvcmQ=
+```typescript
+// Hardcoded configuration
+const config = {
+  appName: 'RxMinder',
+  baseUrl: 'http://localhost:5173',
+  dbUrl: 'http://localhost:5984',
+  adminPassword: 'admin123', // ❌ Security risk
+};
 ```
 
 **Problems:**
 
-- 😣 Manual base64 encoding required
-- 🔧 Error-prone (encoding mistakes)
-- 📝 Hard to read/verify credentials
-- 🔒 Credentials visible in YAML files
+- 😣 No environment flexibility
+- 🔧 Configuration changes require code changes
+- 📝 Hard to customize for different deployments
+- 🔒 Security risks with hardcoded credentials
 
 ### ✅ After (Template-Based)
 
-**New approach uses templates with automatic substitution:**
+**New approach uses environment variables with templates:**
 
-```yaml
-# k8s/couchdb-secret.yaml.template
-apiVersion: v1
-kind: Secret
-metadata:
-  name: couchdb-secret
-  labels:
-    app: ${APP_NAME}
-type: Opaque
-stringData:
-  # Kubernetes automatically base64 encodes stringData
-  username: ${COUCHDB_USER}
-  password: ${COUCHDB_PASSWORD}
+```typescript
+// Environment-based configuration
+const config = {
+  appName: process.env.VITE_APP_NAME || 'RxMinder',
+  baseUrl: process.env.VITE_BASE_URL || 'http://localhost:5173',
+  dbUrl: process.env.VITE_COUCHDB_URL || 'http://localhost:5984',
+  adminPassword: process.env.VITE_COUCHDB_PASSWORD, // ✅ Secure
+};
 ```
 
 **Benefits:**
 
-- ✅ No manual base64 encoding needed
-- ✅ Environment variables from `.env` file
-- ✅ Human-readable configuration

 ## 🚀 How It Works
 
-### 1. Configuration in `.env`
+### 1. Environment Configuration
 
 ```bash
-# .env (user-friendly configuration)
-APP_NAME=my-rxminder
-COUCHDB_USER=admin
-COUCHDB_PASSWORD=super-secure-password-123
-INGRESS_HOST=rxminder.mydomain.com
+# .env.example (template for all environments)
+VITE_APP_NAME=RxMinder
+VITE_BASE_URL=http://localhost:5173
+VITE_COUCHDB_URL=http://localhost:5984
+VITE_COUCHDB_USER=admin
+VITE_COUCHDB_PASSWORD=secure-password-123
+
+# Email configuration (optional)
+VITE_MAILGUN_API_KEY=your-mailgun-api-key
+VITE_MAILGUN_DOMAIN=your-domain.com
+
+# OAuth configuration (optional)
+VITE_GOOGLE_CLIENT_ID=your-google-client-id
+VITE_GITHUB_CLIENT_ID=your-github-client-id
+
+# Feature flags
+ENABLE_EMAIL_VERIFICATION=true
+ENABLE_OAUTH=true
+DEBUG_MODE=false
 ```
 
-### 2. Template Substitution
+### 2. Template Processing
+
+#### HTML Template Processing
+
+```html
+<!-- index.html.template -->
+<!DOCTYPE html>
+<html lang="en">
+  <head>
+    <title>${APP_NAME}</title>
+    <meta name="description" content="${APP_NAME} - Medication Reminder App" />
+  </head>
+</html>
+```
+
+**Processed to:**
+
+```html
+<!-- index.html -->
+<!DOCTYPE html>
+<html lang="en">
+  <head>
+    <title>MyCustomApp</title>
+    <meta name="description" content="MyCustomApp - Medication Reminder App" />
+  </head>
+</html>
+```
+
+#### Configuration Template
+
+```typescript
+// config/unified.config.ts (centralized configuration)
+export const unifiedConfig = {
+  app: {
+    name: import.meta.env.VITE_APP_NAME || 'RxMinder',
+    environment: import.meta.env.NODE_ENV || 'development',
+    baseUrl: import.meta.env.VITE_BASE_URL || 'http://localhost:5173',
+    version: import.meta.env.VITE_APP_VERSION || '0.0.0',
+  },
+  database: {
+    url: import.meta.env.VITE_COUCHDB_URL || 'http://localhost:5984',
+    username: import.meta.env.VITE_COUCHDB_USER || 'admin',
+    password: import.meta.env.VITE_COUCHDB_PASSWORD || '',
+  },
+  features: {
+    emailVerification: import.meta.env.ENABLE_EMAIL_VERIFICATION === 'true',
+    oauth: import.meta.env.ENABLE_OAUTH === 'true',
+    debug: import.meta.env.DEBUG_MODE === 'true',
+  },
+};
+```
+
+### 3. Development vs Production
+
+#### Development Environment
 
 ```bash
-# Automatic substitution with envsubst
-envsubst < k8s/couchdb-secret.yaml.template
+# .env (development)
+VITE_APP_NAME=RxMinder-Dev
+VITE_COUCHDB_URL=http://localhost:5984
+DEBUG_MODE=true
+ENABLE_EMAIL_VERIFICATION=false
 ```
 
-**Result:**
-
-```yaml
-apiVersion: v1
-kind: Secret
-metadata:
-  name: couchdb-secret
-  labels:
-    app: my-rxminder
-type: Opaque
-stringData:
-  username: admin
-  password: super-secure-password-123
-```
-
-### 3. Kubernetes Processing
-
-- Kubernetes automatically base64 encodes `stringData` fields
-- No manual encoding required
-- More secure and reliable
-
-## 🎛️ Deployment Options
-
-### Option 1: Automated Script (Recommended)
+#### Production Environment
 
 ```bash
-# Copy and configure
-cp .env.example .env
-nano .env
-
-# Deploy everything
-./scripts/k8s-deploy-template.sh deploy
+# .env.production
+VITE_APP_NAME=MedicationTracker
+VITE_COUCHDB_URL=https://your-couchdb.com
+ENABLE_EMAIL_VERIFICATION=true
+ENABLE_OAUTH=true
+DEBUG_MODE=false
 ```
 
-### Option 2: Manual Template Processing
+## 🔧 Template Files in Project
 
-```bash
-# Set environment variables
-export APP_NAME=my-rxminder
-export COUCHDB_PASSWORD=secure-password
+### 1. HTML Templates
 
-# Process templates
-envsubst < k8s/couchdb-secret.yaml.template | kubectl apply -f -
-envsubst < k8s/ingress.yaml.template | kubectl apply -f -
-```
+- **`index.html.template`** - Main HTML entry point with variable substitution
+- **`index.html`** - Generated file (processed by `scripts/process-html.sh`)
 
-## 🔧 Template Files Created
+### 2. Configuration Templates
 
-1. **`k8s/couchdb-secret.yaml.template`** - Database credentials
-2. **`k8s/ingress.yaml.template`** - Ingress with custom hostname
-3. **`k8s/configmap.yaml.template`** - Application configuration
-4. **`k8s/frontend-deployment.yaml.template`** - Frontend deployment
-5. **`scripts/k8s-deploy-template.sh`** - Automated deployment script
+- **`.env.example`** - Template for environment configuration
+- **`config/unified.config.ts`** - Centralized configuration with validation
+
+### 3. Processing Scripts
+
+- **`scripts/process-html.sh`** - HTML template processing
+- **`package.json`** - Scripts for template processing (`predev`, `prebuild`)
 
 ## 🛡️ Security Benefits
 
-- **No hardcoded credentials** in version control
-- **Environment-specific configuration** via `.env` files
-- **Automatic validation** of required variables
-- **Kubernetes stringData** (auto base64 encoding)

+### Environment Variable Naming
+
+- Use `VITE_` prefix for client-side variables
+- Use descriptive names (`VITE_COUCHDB_PASSWORD` vs `PASSWORD`)
+- Group related variables (`VITE_MAILGUN_API_KEY`, `VITE_MAILGUN_DOMAIN`)
+
+### Template Organization
+
+- Keep templates close to generated files
+- Use clear naming conventions (`.template` suffix)
+- Document all template variables
+
+### Validation Strategy
+
+- Validate required variables at startup
+- Provide clear error messages for missing configuration
+- Use TypeScript for compile-time validation
+
