-# LFx Tool Executor Node
+# LFX Tool Executor Node
 
-A dedicated executor node for running Langflow tools inside the Droq distributed runtime.  
-It exposes a lightweight FastAPI surface and will eventually host tool-specific logic (AgentQL, scraping helpers, etc.).
+**LFX Tool Executor Node** provides a unified interface for running LangFlow tools inside the Droq distributed runtime
 
-## Quick start
+## 🚀 Installation
+
+### Using UV (Recommended)
 
 ```bash
-cd nodes/lfx-tool-executor-node
+# Install UV
+curl -LsSf https://astral.sh/uv/install.sh | sh
+
+# Clone and setup
+git clone https://github.com/droq-ai/lfx-tool-executor-node.git
+cd lfx-tool-executor-node
 uv sync
 
+# Verify installation
+uv run lfx-tool-executor-node --help
+```
+
+### Using Docker
+
+```bash
+docker build -t lfx-tool-executor-node:latest .
+docker run --rm -p 8005:8005 lfx-tool-executor-node:latest
+```
+
+## 🧩 Usage
+
+### Running the Node
+
+```bash
 # Run locally (defaults to port 8005)
 ./start-local.sh
 
 # or specify a port
-./start-local.sh 8015
+./start-local.sh 8005
+
+# or use uv directly
+uv run lfx-tool-executor-node --port 8005
 ```
 
+### API Endpoints
+
 The server exposes:
 
 - `GET /health` – readiness probe
-- `POST /api/v1/tools/run` – placeholder endpoint that will dispatch tool executions
+- `POST /api/v1/execute` – execute specific tools
 
-## Configuration
+## ⚙️ Configuration
 
 Environment variables:
 
 | Variable | Default | Description |
 | --- | --- | --- |
 | `HOST` | `0.0.0.0` | Bind address |
-| `PORT` | `8005` | HTTP port when no CLI arg is supplied |
+| `PORT` | `8005` | HTTP port |
 | `LOG_LEVEL` | `INFO` | Python logging level |
+| `NODE_ID` | `lfx-tool-executor-node` | Node identifier |
 
-Additional secrets (API keys, service tokens) will be mounted per deployment as tools are added.
 
-## Docker
+## 🔧 Development
 
 ```bash
-docker build -t lfx-tool-executor-node:latest .
-docker run --rm -p 8005:8005 lfx-tool-executor-node:latest
+# Install development dependencies
+uv sync --group dev
+
+# Run tests
+uv run pytest
+
+# Format code
+uv run black src/ tests/
+uv run ruff check src/ tests/
+uv run ruff format src/ tests/
+
+# Type checking
+uv run mypy src/
 ```
