+
+## Architecture Overview
+
+### Core Client Architecture
+
+- **Dual Client Pattern**: `InfrahubClient` (async) and `InfrahubClientSync` (sync) provide identical interfaces
+- **Configuration**: Pydantic-based `Config` class with environment variable support
+- **Transport**: HTTPX-based with proxy support (single proxy or HTTP/HTTPS mounts)
+- **Authentication**: API tokens or JWT with automatic refresh
+
+### Key Modules Structure
+
+```text
+infrahub_sdk/
+├── client.py           # Main client implementations
+├── config.py          # Configuration management with Pydantic
+├── node/              # Node system (core data model)
+│   ├── node.py        # InfrahubNode and InfrahubNodeSync
+│   ├── attribute.py   # Node attributes
+│   └── relationship.py # Relationship management
+├── ctl/               # CLI commands (infrahubctl)
+├── pytest_plugin/    # Custom pytest plugin for Infrahub testing
+└── protocols.py       # Generated protocol classes
+```
+
+### Node System Design
+
+- **Lazy Loading**: Nodes load attributes and relationships on demand
+- **Batch Operations**: Support for bulk create/update/delete operations
+- **Relationship Management**: Automatic handling of node relationships with add/remove/replace operations
+- **Validation**: Built-in data validation with GraphQL query generation
+
+## Infrahub-Specific Patterns
+
+### Checks Implementation
+
+```python
+# CRITICAL: Use validate() method, NOT check()
+class MyCheck(InfrahubCheck):
+    def validate(self, data):  # Must be validate(), not check()
+        # validation logic
+        pass
+```
+
+### Async/Sync Pattern
+
+All operations follow dual implementation pattern:
+
+```python
+# Async version (default)
+client = InfrahubClient()
+node = await client.get(kind="NetworkDevice")
+await node.save()
+
+# Sync version
+client = InfrahubClientSync()
+node = client.get(kind="NetworkDevice")
+node.save()
+```
+
+### Configuration Management
+
+- Environment variables prefixed with `INFRAHUB_`
+- Proxy configuration: `INFRAHUB_PROXY` (single) or `INFRAHUB_PROXY_MOUNTS_HTTP`/`INFRAHUB_PROXY_MOUNTS_HTTPS` (separate)
+- Mutual exclusivity validation between proxy configuration methods
+
+## Testing Framework
+
+### Custom Pytest Plugin
+
+The repository includes a custom pytest plugin (`infrahub_sdk.pytest_plugin`) that provides:
+
+- Fixtures for Infrahub clients and configuration
+- Support for testing checks, transforms, and queries
+- Integration with infrahub-testcontainers for Docker-based testing
+
+### Test Structure
+
+- **Unit Tests**: `tests/unit/` - Test individual components in isolation
+- **Integration Tests**: `tests/integration/` - Test against real Infrahub instances
+- **Coverage Target**: Maintained through codecov integration
+
+## CLI Architecture (`infrahubctl`)
+
+The CLI is built with Typer and provides extensive functionality:
+
+- **Schema Management**: Load, validate, and manage Infrahub schemas
+- **Transformations**: Run Jinja2-based data transformations
+- **Checks**: Execute validation checks against Infrahub data
+- **Branch Operations**: Create, merge, and manage branches
+- **Object Management**: CRUD operations on Infrahub objects
+
+CLI commands are auto-documented and organized in `infrahub_sdk/ctl/`.
+
+## Documentation System
+
+### Structure
+
+- **Docusaurus-based**: React/Node.js documentation system
+- **Auto-generation**: CLI docs and config reference generated via invoke tasks
+- **Multi-format**: Guides (task-oriented) and reference (API documentation)
+
+### Documentation Development
+
+```bash
+# Generate all docs
+poetry run invoke docs
+
+# Start development server (requires Node.js)
+cd docs && npm start
+```
+
+## Development Tooling
+
+### Code Quality
+
+- **Ruff**: Comprehensive linting and formatting (0.11.0)
+- **mypy**: Type checking with strict configuration
+- **yamllint**: YAML file validation
+- **markdownlint**: Documentation consistency
+- **Vale**: Documentation style checking
+
+### CI/CD Integration
+
+GitHub Actions workflow runs:
+
+1. Multi-version Python testing (3.9-3.13)
+2. Comprehensive linting pipeline
+3. Documentation generation and validation
+4. Integration testing with Infrahub containers
+5. Coverage reporting
+

+
+## Documentation Writing Guidelines
+
+When writing or modifying MDX documentation files in this repository, follow these established patterns:
+
+### Framework: Diataxis
+
+All documentation follows the [Diataxis framework](https://diataxis.fr/):
+
+- **Tutorials** (learning-oriented): Step-by-step learning experiences
+- **How-to guides** (task-oriented): Problem-solving instructions
+- **Explanation** (understanding-oriented): Clarification and discussion of topics
+- **Reference** (information-oriented): Technical descriptions and specifications
+
+### Tone and Style
+
+- **Professional but approachable**: Use plain language with technical precision
+- **Concise and direct**: Prefer short, active sentences with minimal fluff
+- **Informative over promotional**: Focus on explaining how and why, not marketing
+- **Consistent structure**: Follow predictable patterns across documents
+
+### Document Structure Patterns
+
+#### How-to Guides (Task-oriented)
+
+```markdown
+---
+title: How to [accomplish specific task]
+---
+
+# Brief introduction stating the problem/goal
+
+## Prerequisites
+- What the user needs before starting
+- Required environment setup
+
+## Step-by-step Instructions
+
+### Step 1: [Action/Goal]
+- Clear, actionable instructions
+- Code snippets with proper language tags
+- Screenshots/images for visual guidance
+- Use Tabs for alternative methods (Web UI, GraphQL, Shell)
+
+### Step 2: [Next Action]
+- Continue structured approach
+
+## Validation
+- How to verify the solution worked
+- Expected outputs and potential issues
+
+## Related Resources
+- Links to related guides and topics
+```
+
+#### Topics (Understanding-oriented)
+
+```markdown
+---
+title: Understanding [concept or feature]
+---
+
+# Introduction to what this explanation covers
+
+## Concepts & Definitions
+- Key terms and how they fit into Infrahub
+
+## Background & Context  
+- Design decisions and rationale
+- Technical constraints and considerations
+
+## Architecture & Design
+- Diagrams and component interactions
+- Mental models and analogies
+
+## Connections
+- How this relates to other Infrahub concepts
+- Integration points and relationships
+
+## Further Reading
+- Links to guides, references, and external resources
+```
+
+### Content Guidelines
+
+#### For Guides
+
+- Use conditional imperatives: "If you want X, do Y"
+- Address users directly: "Configure...", "Create...", "Deploy..."
+- Focus on practical tasks without digressing into explanations
+- Maintain focus on the specific goal
+
+#### For Topics
+
+- Use discursive, reflective tone that invites understanding
+- Include context, background, and rationale behind design decisions
+- Make connections between concepts and existing knowledge
+- Present alternative perspectives where appropriate
+
+### Terminology and Quality
+
+- **Define new terms** when first introduced
+- **Use domain-relevant language** from user perspective (playbooks, branches, schemas, commits)
+- **Be consistent** with Infrahub's data model and UI naming conventions
+- **Validate accuracy** against latest Infrahub version
+- **Follow markdown style** as defined in `.markdownlint.yaml` and Vale styles in `.vale/styles/`
+
+### Code Examples and Formatting
+
+- Use proper language tags for all code blocks
+- Include both async and sync examples where applicable using Tabs component
+- Provide realistic examples that reflect real-world complexity
+- Add validation steps to confirm success
+- Use callouts for warnings, tips, and important notes
