+### Workflow Features
+
+#### 1. Manual Trigger with Parameters
+```yaml
+workflow_dispatch:
+  inputs:
+    build_type:
+      description: 'Build type'
+      default: 'Release'
+      options: [Release, Debug]

-- Use `build-windows-all.sh` for Windows
-- Run Linux builds in parallel
+- All platform builds run in parallel
+- Typical total workflow time: 10-15 minutes
+- Individual job times:
+  - Linux: ~3-5 minutes
+  - Windows: ~3-5 minutes
+  - macOS: ~5-7 minutes

 ## Security Notes
 
 - All builds use official Docker base images
 - Windows builds use native Windows APIs (no OpenSSL dependency)
 - Static linking available for deployment scenarios
-- No runtime dependencies on Windows
+- No runtime dependencies on Windows
+- GitHub Actions uses secure runners with isolated environments
+- Artifacts are scanned by GitHub's security features
+- Release binaries should be signed before distribution
+
+## Monitoring Builds
+
+### GitHub Actions Dashboard
+- View all runs: `https://github.com/[owner]/mcp-cpp-sdk/actions`
+- Specific workflow: Click on "Build All Libraries"
+- Real-time logs: Click on any running job
+
+### Status Badges
+Add to README.md:
+```markdown
+[![Build All Libraries](https://github.com/[owner]/mcp-cpp-sdk/actions/workflows/build-all.yml/badge.svg)](https://github.com/[owner]/mcp-cpp-sdk/actions/workflows/build-all.yml)

+
+## Troubleshooting GitHub Actions
+
+### Common Issues
+
+1. **Runner not available**
+   - `macos-15-intel` may have limited availability
+   - Fallback: Use `macos-13` or `macos-latest`
+
+2. **Build failures**
+   - Check the job logs for specific errors
+   - Verify dependencies are correctly specified
+   - Ensure scripts have execute permissions
+
+3. **Artifact upload failures**
+   - Check artifact size limits (500MB default)
+   - Verify file paths are correct
+   - Ensure retention days are within limits
+
+4. **Release creation failures**
+   - Verify GITHUB_TOKEN has write permissions
+   - Check tag naming doesn't conflict
+   - Ensure all artifacts exist before release
+
+### Re-running Failed Jobs
+```bash
+# Re-run all jobs
+gh run rerun [run-id]
+
+# Re-run only failed jobs
+gh run rerun [run-id] --failed
+
+# View specific job logs
+gh run view [run-id] --log
+```
+
+## Best Practices
+
+### For Contributors
+1. Test locally before pushing
+2. Use draft PRs for work in progress
+3. Include platform info in commit messages
+4. Run linting and formatting locally
+
+### For Maintainers
+1. Tag releases semantically (v0.1.0, v0.2.0)
+2. Update version in CMakeLists.txt
+3. Document breaking changes
+4. Sign release binaries when possible
+5. Test artifacts before announcing releases
+
+### For CI/CD
+1. Use matrix builds for efficiency
+2. Cache dependencies where possible
+3. Parallelize independent jobs
+4. Set appropriate timeout values
+5. Use secrets for sensitive data
+6. Regular cleanup of old artifacts
