-# Kairo Python SDK
+# Microsoft Agent 365 Python SDK
 
-A Python SDK for Kairo, providing telemetry and monitoring capabilities.
+The Microsoft Agent365 SDK provides comprehensive observability, tooling, and runtime capabilities for AI agents and tools built with Python.
 
-## Installation
+## 📚 Library Documentation
 
-```bash
-pip install microsoft-kairo
-```
+Each library includes comprehensive documentation:
 
-## Usage
-
-### Basic Configuration
-
-```python
-import microsoft_kairo
-
-# Configure Kairo with console output (default)
-microsoft_kairo.configure_kairo(
-    service_name="my-service",
-    service_namespace="my-namespace",
-    agent_id="agent-123"
-)
-```
-
-### Advanced Configuration
-
-```python
-import microsoft_kairo
-
-# Configure with Azure Monitor
-microsoft_kairo.configure_kairo(
-    service_name="my-service",
-    service_namespace="my-namespace",
-    agent_id="agent-123",
-    exporter_type="azure_monitor",
-    exporter_endpoint="InstrumentationKey=your-instrumentation-key"
-)
-
-# Configure with OTLP exporter
-microsoft_kairo.configure_kairo(
-    service_name="my-service",
-    service_namespace="my-namespace", 
-    agent_id="agent-123",
-    exporter_type="otlp",
-    exporter_endpoint="http://localhost:4317"
-)
-```
-
-### Available Exports
-
-- `configure_kairo()`: Main configuration function
-- `KairoSpanProcessor`: Custom span processor class
-- `KAIRO_AGENT_ID_KEY`: Constant for agent ID attribute key
-
-## Optional Dependencies
-
-- `otlp`: OpenTelemetry OTLP exporter
-- `jaeger`: Jaeger exporter
-- `azure`: Azure Monitor exporter
-- `all`: All optional dependencies
-
-Install with optional dependencies:
-
-```bash
-pip install microsoft-kairo[azure]
-```
-
-## Building and publishing the package
-
-Build the package with:
-
-```
-uv build --wheel
-```
-
-which will generate a date-based wheel package in the `dist/` folder. Ex.: `dist\microsoft_kairo-2025.10.7+preview.15276-py3-none-any.whl`.
-
-Then publish it with:
-
-```
-uv run twine upload --config-file .\.pypirc -r Agent365 dist/*
-```

 Prefer the canonical `ENABLE_A365_OBSERVABILITY_EXPORTER`. If you omit `ENABLE_OBSERVABILITY` or set it to false, scopes become no‑ops and no spans are recorded.
