+# Plugin Analytics
+
+## Status
+✅ Operational
+
+## Overview
+Analytics plugin for collecting, processing, and analyzing data from various AITBC components and services.
+
+## Architecture
+
+### Core Components
+- **Data Collector**: Collects data from services and plugins
+- **Data Processor**: Processes and normalizes collected data
+- **Analytics Engine**: Performs analytics and generates insights
+- **Report Generator**: Generates reports and visualizations
+- **Storage Manager**: Manages data storage and retention
+
+## Quick Start (End Users)
+
+### Prerequisites
+- Python 3.13+
+- PostgreSQL database
+- Access to service metrics endpoints
+
+### Installation
+```bash
+cd /opt/aitbc/apps/plugin-analytics
+.venv/bin/pip install -r requirements.txt
+```
+
+### Configuration
+Set environment variables in `.env`:
+```bash
+DATABASE_URL=postgresql://user:pass@localhost/analytics
+COLLECTION_INTERVAL=300
+RETENTION_DAYS=90
+```
+
+### Running the Service
+```bash
+.venv/bin/python main.py
+```
+
+## Developer Guide
+
+### Development Setup
+1. Clone the repository
+2. Create virtual environment: `python -m venv .venv`
+3. Install dependencies: `pip install -r requirements.txt`
+4. Set up database
+5. Configure data sources
+6. Run tests: `pytest tests/`
