+# Database Migration CI/CD Guide
+
+This document describes the automated database migration pipeline for Brain-Storm.
+
+## Overview
+
+The CI/CD pipeline automatically validates, tests, and reports on database migrations to ensure safe and reliable schema changes.
+
+## Automated Checks
+
+### 1. Migration Validation
+- **File Structure**: Ensures all migrations have `up()` and `down()` methods
+- **Naming Convention**: Validates timestamp-based naming (e.g., `1234567890123-Description.ts`)
+- **Ordering**: Checks that migrations are in chronological order
+- **Duplicates**: Detects duplicate timestamps
+
+### 2. Dry-Run Testing
+- Runs migrations on a test PostgreSQL database
+- Verifies all migrations execute successfully
+- Tests rollback functionality
+- Ensures no data loss during migration
+
+### 3. Migration Reports
+- Generates comprehensive migration reports
+- Lists all migration files with timestamps
+- Comments on PRs with migration status
+- Tracks migration history
+
+## Workflow Triggers
+
+The migration CI/CD pipeline runs automatically when:
+- Pull requests modify files in `apps/backend/src/migrations/`
+- Pull requests modify files in `apps/backend/src/entities/`
+- Code is pushed to `main` branch with migration changes
+
+## Creating a New Migration
+
+### Step 1: Generate Migration
+```bash
+cd apps/backend
+npm run migration:generate -- src/migrations/AddNewFeature
+```
+
+### Step 2: Review Generated Migration
+```bash
+cat src/migrations/1234567890123-AddNewFeature.ts
+```
+
+### Step 3: Test Locally
+```bash
+npm run migration:run
+npm run migration:rollback
+```
+
+### Step 4: Commit and Push
+```bash
+git add src/migrations/
+git commit -m "feat: add new feature migration"
+git push
+```
+
+The CI/CD pipeline will automatically validate and test your migration.
+
+## Migration Best Practices
+
+### 1. One Concern Per Migration
+Each migration should handle a single logical change:
+```typescript
+// ✅ Good: Single concern
+export class AddUserEmailColumn1234567890123 implements MigrationInterface {
+  public async up(queryRunner: QueryRunner): Promise<void> {
+    await queryRunner.addColumn('users', new TableColumn({
+      name: 'email',
+      type: 'varchar',
+      isUnique: true,
+    }));
+  }
+  
+  public async down(queryRunner: QueryRunner): Promise<void> {
+    await queryRunner.dropColumn('users', 'email');
+  }
+}
+```
+
+### 2. Always Implement Down Method
+Ensure rollback capability:
+```typescript
+// ✅ Good: Complete rollback
+public async down(queryRunner: QueryRunner): Promise<void> {
+  await queryRunner.dropColumn('users', 'email');
+}
+
+// ❌ Bad: Incomplete rollback
+public async down(queryRunner: QueryRunner): Promise<void> {
+  // Empty or incomplete
+}
+```
+
+### 3. Use Transactions
+Migrations automatically run in transactions for safety:
+```typescript
+// ✅ Good: Transactional
+export class MyMigration1234567890123 implements MigrationInterface {
+  public async up(queryRunner: QueryRunner): Promise<void> {
+    // All operations are transactional
+    await queryRunner.addColumn(...);
+    await queryRunner.createIndex(...);
+  }
+}
+```
+
+### 4. Handle Data Migrations Carefully
+For data migrations, include validation:
+```typescript
+export class MigrateUserData1234567890123 implements MigrationInterface {
+  public async up(queryRunner: QueryRunner): Promise<void> {
+    // Validate data before migration
+    const count = await queryRunner.query('SELECT COUNT(*) FROM users');
+    console.log(`Migrating ${count[0].count} users...`);
+    
+    // Perform migration
+    await queryRunner.query('UPDATE users SET status = ? WHERE status IS NULL', ['active']);
+  }
+  
+  public async down(queryRunner: QueryRunner): Promise<void> {
+    await queryRunner.query('UPDATE users SET status = NULL WHERE status = ?', ['active']);
+  }
+}
+```
+
+## Troubleshooting
+
+### Migration Validation Fails
+
+**Issue**: "Invalid naming convention"
+```
+❌ Invalid naming convention: AddUserTable.ts
+Expected format: TIMESTAMP-Description.ts
+```
+
+**Solution**: Rename file to include timestamp:
+```bash
+mv src/migrations/AddUserTable.ts src/migrations/1234567890123-AddUserTable.ts
+```
+
+### Dry-Run Test Fails
+
+**Issue**: "Migration failed on test database"
+
+**Solution**:
+1. Check migration syntax for SQL errors
+2. Verify column/table names exist
+3. Test locally first:
+   ```bash
+   npm run migration:run
+   npm run migration:rollback
+   ```
+
+### Rollback Test Fails
+
+**Issue**: "Rollback test failed"
+
+**Solution**: Ensure `down()` method properly reverses `up()`:
+```typescript
+// ✅ Correct: Mirrors up() exactly
+public async down(queryRunner: QueryRunner): Promise<void> {
+  await queryRunner.dropColumn('users', 'email');
+}
+```
+
+## Production Deployment
+
+### Pre-Deployment Checklist
+- [ ] All migrations pass CI/CD validation
+- [ ] Dry-run tests pass on test database
+- [ ] Rollback tested and verified
+- [ ] Database backup created
+- [ ] Deployment window scheduled
+- [ ] Team notified
+
+### Deployment Steps
+1. Deploy new code with migrations
+2. Run migrations on production:
+   ```bash
+   npm run migration:run
+   ```
+3. Verify application functionality
+4. Monitor logs for errors
+5. Keep rollback plan ready
+
+### Rollback Procedure
+If issues occur:
+```bash
+npm run migration:rollback
+# Repeat as needed to revert multiple migrations
+```
+
+## Monitoring and Alerts
+
+The CI/CD pipeline provides:
+- ✅ Automatic validation on every PR
+- ✅ Test database dry-run verification
+- ✅ PR comments with migration status
+- ✅ Detailed migration reports
+- ✅ Rollback testing

+```
+
+## Documenting Your API
+
+### 1. Using NestJS Swagger Decorators
+
+```typescript
+import { Controller, Get, Post, Body } from '@nestjs/common';
+import { ApiOperation, ApiResponse, ApiTags } from '@nestjs/swagger';
+
+@ApiTags('courses')
+@Controller('courses')
+export class CoursesController {
+  @Get()
+  @ApiOperation({ summary: 'List all courses' })
+  @ApiResponse({ status: 200, description: 'List of courses' })
+  findAll() {
+    // Implementation
+  }
+
+  @Post()
+  @ApiOperation({ summary: 'Create a new course' })
+  @ApiResponse({ status: 201, description: 'Course created' })
+  create(@Body() createCourseDto: CreateCourseDto) {
+    // Implementation
+  }
+}
+```
+
+### 2. Documenting DTOs
+
+```typescript
+import { ApiProperty } from '@nestjs/swagger';
+
+export class CreateCourseDto {
+  @ApiProperty({
+    description: 'Course title',
+    example: 'Introduction to Stellar',
+  })
+  title: string;
+
+  @ApiProperty({
+    description: 'Course description',
+    example: 'Learn the basics of Stellar blockchain',
+  })
+  description: string;
+
+  @ApiProperty({
+    description: 'Course difficulty level',
+    enum: ['beginner', 'intermediate', 'advanced'],
+    example: 'beginner',
+  })
+  level: string;
+}
+```
+
+### 3. Documenting Responses
+
+```typescript
+@Get(':id')
+@ApiOperation({ summary: 'Get course by ID' })
+@ApiResponse({
+  status: 200,
+  description: 'Course found',
+  type: CourseDto,
+})
+@ApiResponse({
+  status: 404,
+  description: 'Course not found',
+})
+getCourse(@Param('id') id: string) {
+  // Implementation
+}
+```
+
+## Exporting OpenAPI Specification
+
+### Manual Export
+
+```bash
+cd apps/backend
+EXPORT_OPENAPI=true npm run start
+# OpenAPI spec exported to openapi.json
+```
+
+### Automatic Export (CI/CD)
+
+The CI/CD pipeline automatically exports the OpenAPI spec on every push to main.
+
+## Breaking Changes Detection
+
+The pipeline automatically detects breaking changes:
+
+```
+⚠️ Breaking Changes Detected:
+- Removed endpoint: DELETE /v1/courses/:id
+- Changed response type: GET /v1/users/:id
+- Removed field: User.email
+```
+
+## SDK Generation
+
+### TypeScript SDK
+
+Generated automatically and available in `packages/sdk-typescript/`
+
+**Installation**:
+```bash
+npm install @brain-storm/sdk
+```
+
+**Usage**:
+```typescript
+import { CoursesApi } from '@brain-storm/sdk';
+
+const api = new CoursesApi();
+const courses = await api.getCourses();
+```
+
+### Python SDK
+
+Generated automatically and available in `packages/sdk-python/`
+
+**Installation**:
+```bash
+pip install brain-storm-sdk
+```
+
+**Usage**:
+```python
+from brain_storm_sdk import CoursesApi
+
+api = CoursesApi()
+courses = api.get_courses()
+```
+
+## Documentation Versioning
+
+### Version History
+
+The `versions.json` file maintains version history:
+
+```json
+{
+  "current": "1.2.0",
+  "versions": [
+    {
+      "version": "1.2.0",
+      "url": "./index.html",
+      "redoc": "./redoc.html",
+      "date": "2026-06-01T05:44:31Z"
+    },
+    {
+      "version": "1.1.0",
+      "url": "./v1.1.0/index.html",
+      "redoc": "./v1.1.0/redoc.html",
+      "date": "2026-05-15T10:30:00Z"
+    }
+  ]
+}
+```
+
+### Accessing Previous Versions
+
+Previous API versions are archived and accessible via GitHub Pages.
+
+## Search Functionality
+
+The `search-index.json` provides full-text search capabilities:
+
+```json
+{
+  "version": "1.2.0",
+  "endpoints": [
+    {
+      "path": "/v1/courses",
+      "methods": ["GET", "POST"],
+      "tags": ["courses"]
+    }
+  ],
+  "schemas": [
+    {
+      "name": "CourseDto",
+      "description": "Course data transfer object"
+    }
+  ],
+  "tags": ["courses", "users", "auth"]
+}
+```
+
+## PR Preview
+
+When you create a pull request that modifies the API:
+
+1. The pipeline validates the OpenAPI spec
+2. Generates documentation preview
+3. Comments on the PR with preview links
+4. Detects breaking changes
+
+Example PR comment:
+```
+## 📚 API Documentation Preview
+
+**Version**: 1.2.0
+
+- [Swagger UI](...)
+- [ReDoc](...)
+
+Documentation will be deployed to GitHub Pages on merge to main.
+```
+
+## Deployment
+
+### GitHub Pages Deployment
+
+Documentation is automatically deployed to GitHub Pages when:
+- Code is pushed to `main` branch
+- API changes are detected
+
+**Access**: `https://your-org.github.io/Brain-Storm/`
+
+### Custom Domain Deployment
+
+To deploy to a custom domain:
+
+1. Configure GitHub Pages in repository settings
+2. Add custom domain
+3. Update DNS records
+4. Documentation will be available at your custom domain
+
+## Troubleshooting
+
+### OpenAPI Validation Fails
+
+**Issue**: "Invalid OpenAPI specification"
+
+**Solution**:
+1. Check NestJS Swagger decorators
+2. Verify all endpoints are documented
+3. Ensure DTOs have proper decorators
+4. Run validation locally:
+   ```bash
+   swagger-cli validate apps/backend/openapi.json
+   ```
+
+### Documentation Not Updating
+
+**Issue**: "Documentation not deployed"
+
+**Solution**:
+1. Check GitHub Actions logs
+2. Verify backend changes are detected
+3. Ensure OpenAPI export is working
+4. Check GitHub Pages settings
+
+### SDK Generation Fails
+
+**Issue**: "SDK generation failed"
+
+**Solution**:
+1. Verify OpenAPI spec is valid
+2. Check OpenAPI Generator CLI installation
+3. Review SDK generation logs
+4. Ensure all endpoints are documented
+
+## Best Practices
+
+### 1. Keep Documentation Updated
+- Document all new endpoints immediately
+- Update documentation when changing API
+- Include examples in documentation
+
+### 2. Use Meaningful Descriptions
+```typescript
+// ✅ Good: Clear, descriptive
+@ApiOperation({ summary: 'Get all published courses' })
+
+// ❌ Bad: Vague
+@ApiOperation({ summary: 'Get courses' })
+```
+
+### 3. Document Error Responses
+```typescript
+@ApiResponse({ status: 400, description: 'Invalid input' })
+@ApiResponse({ status: 401, description: 'Unauthorized' })
+@ApiResponse({ status: 404, description: 'Course not found' })
+```
+
+### 4. Include Examples
+```typescript
+@ApiProperty({
+  example: 'Introduction to Stellar',
+  description: 'Course title',
+})
+title: string;
+```
+
+### 5. Version Your API
+- Use versioning in routes: `/v1/`, `/v2/`
+- Maintain backward compatibility
+- Document deprecations
