## 🏗️ Standard Template Pattern
|
|
|
|
**All examples follow the same efficient template pattern established with hello-world:**
|
|
|
|
```
|
|
📁 example-name/
|
|
├── 📄 example-name.md ← Complete guide + troubleshooting
|
|
├── 📄 example-name-deployment.yaml ← Application logic
|
|
└── 📄 example-name-service.yaml ← Networking configuration
|
|
```
|
|
|
|
**Template Benefits**:
|
|
- ✅ Consistent structure across all examples
|
|
- ✅ Easy to copy and adapt for new examples
|
|
- ✅ Self-contained documentation in each example
|
|
- ✅ Clear separation of concerns (app vs networking)
|
|
- ✅ Proven pattern tested and working on MyceliumCloud
|
|
|
|
