🏗️ 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

📚 Documentation Standards

Individual Example Structure

Each example includes:

• Quick Start Guide - 5-minute deployment
• Architecture Overview - What it does and why
• Step-by-Step Deployment - Copy-paste commands
• Testing Instructions - How to verify it works
• Troubleshooting Section - Common issues and solutions
• Cleanup Instructions - How to remove resources
• Pro Tips - Advanced usage and best practices

Example Pattern Consistency

• Easy Examples: 30-45 minutes to complete
• Medium Examples: 1-2 hours to complete
• Hard Examples: 2-4 hours to complete
• Very Hard Examples: 4+ hours to complete

🚀 Next Steps

Immediate Next Step

1. Create Nginx Static Site example using hello-world template
   • Copy hello-world structure
   • Adapt for nginx static content serving
   • Include custom HTML/CSS examples
   • Test end-to-end on MyceliumCloud cluster

Development Workflow

1. Use Template: Copy from previous successful example
2. Adapt Content: Modify for specific application needs
3. Test on Cluster: Verify works on MyceliumCloud
4. Document Thoroughly: Include troubleshooting section
5. Verify Pattern: Ensure consistent with overall strategy

Quality Standards

• All examples must be end-to-end tested
• All examples must follow the standard template
• All examples must include troubleshooting sections
• All examples must be copy-paste ready
• All examples must include cleanup instructions
