2. [Multi-Tenancy](docs/01-architecture/multi-tenancy.md) - Tenant isolation model
3. [Data Model](docs/02-core-concepts/data-model/) - Entity relationships

For Device Development:

1. [Device Provisioning](docs/02-core-concepts/device-provisioning.md) - How devices join
2. [Transport Layer](docs/05-transport-layer/) - MQTT, CoAP, HTTP protocols
3. [Device API](docs/06-api-layer/device-api.md) - Telemetry and RPC

For Backend Development:

1. [Rule Engine](docs/04-rule-engine/) - Data processing pipelines
2. [Actor System](docs/03-actor-system/) - Concurrency model
3. [Data Persistence](docs/07-data-persistence/) - Database configuration

For Operations:

Reference Source Code

The ref/ directory contains source code for analysis:

```bash

~/work/viaanix/thingsboard-master/ # Platform source (Java/Angular)

~/work/viaanix/thingsboard.github.io-master/ # Official docs (Jekyll)

```

Building ThingsBoard (from ~/work/viaanix/thingsboard-master):

```bash

# Full backend build

./build.sh

# Frontend development

cd ui-ngx

npm start # Dev server at localhost:4200

```

Style Guidelines

• Mermaid diagrams for architecture visualization
• Tables for configuration options and comparisons
• Code blocks for configuration examples
• Bold for UI elements, backticks for code/variables
• Action-oriented headings: "Configure rate limiting" not "Rate limiting configuration"

Cross-References

Each section README includes:

• Contents table with descriptions
• Key concepts summary
• See Also links to related sections

Target Audience

This documentation targets junior to mid-level developers who need to:

• Understand ThingsBoard's architecture
• Extend platform functionality
• Deploy and operate ThingsBoard
• Integrate devices and external systems

Adding Documentation

1. Place new files in the appropriate docs/##-section/ directory
2. Update the section's README.md contents table
3. Add cross-references to related documents
4. Include Mermaid diagrams for complex concepts
5. Update CLAUDE.md file counts if adding new files

Documentation Quality

• Lead with what to do, then explain why
• Keep explanations concise and actionable
• Use real configuration examples
• Include troubleshooting sections
• Avoid Java-specific implementation details (focus on behavior/contracts)

File Counts

Current documentation: 115 markdown files

Update CLAUDE.md when adding/removing documentation files.
