+# RAGFlow Project Instructions for GitHub Copilot
+
+This file provides context, build instructions, and coding standards for the RAGFlow project.
+It is structured to follow GitHub Copilot's [customization guidelines](https://docs.github.com/en/copilot/concepts/prompting/response-customization).
+
+## 1. Project Overview
+RAGFlow is an open-source RAG (Retrieval-Augmented Generation) engine based on deep document understanding. It is a full-stack application with a Python backend and a React/TypeScript frontend.
+
+- **Backend**: Python 3.10+ (Flask/Quart)
+- **Frontend**: TypeScript, React, UmiJS
+- **Architecture**: Microservices based on Docker.
+  - `api/`: Backend API server.
+  - `rag/`: Core RAG logic (indexing, retrieval).
+  - `deepdoc/`: Document parsing and OCR.
+  - `web/`: Frontend application.
+
+## 2. Directory Structure
+- `api/`: Backend API server (Flask/Quart).
+  - `apps/`: API Blueprints (Knowledge Base, Chat, etc.).
+  - `db/`: Database models and services.
+- `rag/`: Core RAG logic.
+  - `llm/`: LLM, Embedding, and Rerank model abstractions.
+- `deepdoc/`: Document parsing and OCR modules.
+- `agent/`: Agentic reasoning components.
+- `web/`: Frontend application (React + UmiJS).
+- `docker/`: Docker deployment configurations.
+- `sdk/`: Python SDK.
+- `test/`: Backend tests.
+
+## 3. Build Instructions
+
+### Backend (Python)
+The project uses **uv** for dependency management.
+
+1. **Setup Environment**:
+   ```bash
+   uv sync --python 3.11 --all-extras
+   uv run download_deps.py
+   ```
+
+2. **Run Server**:
+   - **Pre-requisite**: Start dependent services (MySQL, ES/Infinity, Redis, MinIO).
+     ```bash
+     docker compose -f docker/docker-compose-base.yml up -d
+     ```
+   - **Launch**:
+     ```bash
+     source .venv/bin/activate
+     export PYTHONPATH=$(pwd)
+     bash docker/launch_backend_service.sh
+     ```
+
+### Frontend (TypeScript/React)
+Located in `web/`.
+
+1. **Install Dependencies**:
+   ```bash
+   cd web
+   npm install
+   ```
+
+2. **Run Dev Server**:
+   ```bash
+   npm run dev
+   ```
+   Runs on port 8000 by default.
+
+### Docker Deployment
+To run the full stack using Docker:
+```bash
+cd docker
+docker compose -f docker-compose.yml up -d
+```
+
+## 4. Testing Instructions
+
+### Backend Tests
+- **Run All Tests**:
+  ```bash
+  uv run pytest
+  ```
+- **Run Specific Test**:
+  ```bash
+  uv run pytest test/test_api.py
+  ```
+
+### Frontend Tests
+- **Run Tests**:
+  ```bash
+  cd web
+  npm run test
+  ```
+
+## 5. Coding Standards & Guidelines
+- **Python Formatting**: Use `ruff` for linting and formatting.
+  ```bash
+  ruff check
+  ruff format
+  ```
+- **Frontend Linting**:
+  ```bash
+  cd web
+  npm run lint
+  ```
+- **Pre-commit**: Ensure pre-commit hooks are installed.
+  ```bash
+  pre-commit install
+  pre-commit run --all-files
+  ```
+
