+This document describes the npm publishing process for the FML Runner monorepo packages with integrated Kotlin/JS build workflow.
+
+## Build Architecture
+
+The FML Runner project uses a **hybrid build system** combining:
+- **Kotlin Multiplatform** for core business logic (JVM + JavaScript targets)
+- **NPM packages** for JavaScript/Node.js distribution  
+- **Integrated GitHub Actions workflows** ensuring Kotlin/JS artifacts are packaged for NPM
+
+### Workflow Integration
+
+```
+Kotlin/JS Build → Artifact Preparation → NPM Publishing
+```
+
+1. **`kotlin-js.yml`**: Builds Kotlin multiplatform code, runs tests, uploads JS artifacts
+2. **`publish-npm.yml`**: Downloads Kotlin/JS artifacts, packages for NPM, publishes
+
+The NPM workflow automatically depends on successful Kotlin/JS builds, ensuring published packages always include the latest compiled Kotlin code.
 
 ## Package Overview
 
 The FML Runner project consists of 4 npm packages published to the public npm registry:
 
-| Package | Description | NPM Link |
-|---------|-------------|----------|
-| **fmlrunner** | Core FML library with compilation and execution | [npm](https://www.npmjs.com/package/fmlrunner) |
-| **fmlrunner-rest** | REST API server with FHIR endpoints | [npm](https://www.npmjs.com/package/fmlrunner-rest) |
-| **fmlrunner-mcp** | Model Context Protocol interface for AI tools | [npm](https://www.npmjs.com/package/fmlrunner-mcp) |
-| **fmlrunner-web** | React web interface and documentation | [npm](https://www.npmjs.com/package/fmlrunner-web) |
+| Package | Description | Dependencies | NPM Link |
+|---------|-------------|--------------|----------|
+| **fmlrunner** | Core FML library with Kotlin/JS implementation | Kotlin/JS artifacts | [npm](https://www.npmjs.com/package/fmlrunner) |
+| **fmlrunner-rest** | REST API server with FHIR endpoints | fmlrunner | [npm](https://www.npmjs.com/package/fmlrunner-rest) |
+| **fmlrunner-mcp** | Model Context Protocol interface for AI tools | fmlrunner | [npm](https://www.npmjs.com/package/fmlrunner-mcp) |

 ## Publishing Workflow Details
 
+### Build Process Integration
+
+The publishing workflow integrates Kotlin/JS and NPM builds:
+
+1. **Kotlin/JS Build Stage**
+   - ✅ **Kotlin Compilation** - Multi-platform code compilation
+   - ✅ **Kotlin Testing** - JVM and JavaScript test execution
+   - ✅ **Artifact Generation** - JavaScript build outputs created
+   - ✅ **Artifact Upload** - Build artifacts uploaded for NPM stage
+
+2. **NPM Publishing Stage**  
+   - ✅ **Artifact Download** - Kotlin/JS artifacts retrieved
+   - ✅ **Artifact Preparation** - Copy JS files to package dist directories
+   - ✅ **Package Validation** - Verify all required files present
+   - ✅ **Quality Checks** - Additional validation and testing
+   - ✅ **NPM Publishing** - Packages published to registry
+
 ### Dependency Order
 
 Packages are published in dependency order:
 
-1. **fmlrunner** (core library) - published first
+1. **fmlrunner** (core library with Kotlin/JS) - published first
 2. **fmlrunner-rest** (depends on fmlrunner)

-- ✅ **Testing** - All test suites pass

+# Kotlin/JS and NPM Workflow Integration
+
+This document describes the integration between the Kotlin multiplatform build and NPM publishing workflows for the FML Runner project.
+
+## Overview
+
+The FML Runner project now uses an integrated build system that:
+1. Builds Kotlin/JS artifacts from the multiplatform codebase
+2. Automatically packages these artifacts into NPM packages
+3. Publishes the packages to the NPM registry with proper dependency management
+
+## Workflow Architecture
+
+```mermaid
+graph LR
+    A[kotlin-js.yml] --> B[Build Kotlin/JS]
+    B --> C[Run Tests]
+    C --> D[Upload Artifacts]
+    D --> E[publish-npm.yml]
+    E --> F[Download Artifacts]
+    F --> G[Prepare NPM Packages]
+    G --> H[Validate & Publish]
+```
+
+### Primary Workflows
+
+1. **kotlin-js.yml** - Kotlin Multiplatform Build
+   - Builds JVM and JavaScript targets
+   - Runs comprehensive test suites
+   - Uploads JavaScript artifacts for NPM packaging
+   - Can be triggered independently or called by other workflows
+
+2. **publish-npm.yml** - NPM Publishing with Kotlin/JS Integration
+   - Depends on successful Kotlin/JS build
+   - Downloads and prepares Kotlin/JS artifacts
+   - Validates package contents
+   - Publishes to NPM registry
+
+## Key Integration Points
+
+### 1. Workflow Dependencies
+
+```yaml
+jobs:
+  build-kotlin:
+    uses: ./.github/workflows/kotlin-js.yml
+
+  publish:
+    runs-on: ubuntu-latest
+    needs: build-kotlin
+```
+
+The NPM publish workflow now depends on the Kotlin build, ensuring JavaScript artifacts are always fresh.
+
+### 2. Artifact Management
+
+```yaml
+- name: Download Kotlin/JS artifacts
+  uses: actions/download-artifact@v4
+  with:
+    name: kotlin-js-build
+    path: build/
+```
+
+Kotlin/JS build outputs are automatically downloaded and made available for NPM packaging.
+
+### 3. Package Preparation
+
+```yaml
+- name: Prepare Kotlin/JS artifacts for NPM
+  run: |
+    mkdir -p packages/fmlrunner/dist
+    cp build/dist/js/productionExecutable/fmlrunner.js packages/fmlrunner/dist/
+```
+
+The workflow automatically copies Kotlin-generated JavaScript files to the appropriate NPM package directories.
+
+## Package Structure
+
+### Core Package (packages/fmlrunner/)
+
+```
+packages/fmlrunner/
+├── package.json          # NPM package configuration
+├── README.md            # Package documentation
+├── fmlrunner.d.ts       # TypeScript definitions
+└── dist/                # Kotlin/JS artifacts (created during build)
+    ├── fmlrunner.js     # Main JavaScript bundle
+    └── fmlrunner.js.map # Source map for debugging
+```
+
+### Version Management
+
+The project includes a unified version management system:
+
+```bash
+# View current version
+npm run version:current
+
+# Bump versions across all packages
+npm run version:patch    # 0.1.0 → 0.1.1
+npm run version:minor    # 0.1.0 → 0.2.0
+npm run version:major    # 0.1.0 → 1.0.0
+
+# Test publishing
+npm run publish:dry-run
+
+# Publish all packages
+npm run publish:all
+```
+
+## Benefits of Integration
+
+1. **Consistency**: NPM packages always contain the latest Kotlin/JS code
+2. **Automation**: No manual steps required to sync builds
+3. **Quality Assurance**: Both Kotlin and NPM tests must pass before publishing
+4. **Type Safety**: TypeScript definitions provide excellent developer experience
+5. **Cross-Platform**: Single codebase targets both JVM and JavaScript platforms
+
+## Developer Workflow
+
+For developers working on the project:
+
+1. **Development**: Write Kotlin code in `src/commonMain/kotlin/`
+2. **Testing**: Run `gradle test` for comprehensive testing
+3. **Building**: Run `gradle build` to generate all artifacts
+4. **Publishing**: Use GitHub Actions workflow for NPM publishing
+
+The integration ensures that any changes to the Kotlin codebase are automatically reflected in the published NPM packages, maintaining consistency across all distribution channels.
+
+## Future Enhancements
+
+The current integration provides a solid foundation for:
+- Additional NPM packages (fmlrunner-rest, fmlrunner-mcp, fmlrunner-web)
+- Enhanced TypeScript definitions generated from Kotlin
+- Automated semantic versioning based on commit messages
+- Integration testing between Kotlin/JS and TypeScript codebases
