-## 🔄 Git Workflow
+## 🔄 Git Workflow and Versioning
+
+This project follows **Semantic Versioning 2.0.0** and **Harvard Data Management file naming conventions**. See [FILE-NAMING-AND-VERSIONING.md](FILE-NAMING-AND-VERSIONING.md) for complete details.
+
+### File Naming Standards
+- **No spaces**: Use hyphens (-) instead of spaces
+- **Date format**: YYYY-MM-DD for chronological sorting
+- **Versioning**: Follow semantic versioning (MAJOR.MINOR.PATCH)
+- **Examples**: `my-project_bom_v1.2.0_2024-08-04.csv`
 
 ### Initial Setup
 ```bash
 # After creating your KiCad project
 git add .
-git commit -m "Add KiCad project files"
+git commit -m "Add KiCad project files v1.0.0"
+git tag -a v1.0.0 -m "Initial release - functional prototype"
 git push
+git push --tags
 ```
 
 ### Regular Development
 ```bash
 # After making changes
 git add .
-git commit -m "Describe your changes"
+git commit -m "Update component values - v1.0.1"
+git tag -a v1.0.1 -m "Bug fix - corrected resistor values"
 git push
+git push --tags
 ```
 
 ### Release Preparation
 ```bash
-# Generate manufacturing files
-# Update documentation
-# Tag release
-git tag -a v1.0.0 -m "Release version 1.0.0"
+# Generate manufacturing files with version numbers
+# Update documentation with new version
+# Tag release following semantic versioning
+git tag -a v2.0.0 -m "Major PCB redesign with new connector layout"
 git push --tags
 ```
 
+### Version Strategy
+- **MAJOR**: PCB layout changes, connector changes, mechanical incompatibilities
+- **MINOR**: Component changes, new features, firmware updates
+- **PATCH**: Documentation updates, BOM corrections, minor fixes
