# Overview

## Introduction

This guide covers running MAP Relay Chain (Atlas) nodes. Different node types serve different purposes in the network.

## Node Types

| Type           | Purpose            | Storage      | Use Case              |
| -------------- | ------------------ | ------------ | --------------------- |
| Full Node      | Validate and relay | Pruned state | General participation |
| Archive Node   | Store full history | Full state   | Historical queries    |
| RPC Node       | Serve API requests | Pruned/Full  | DApp backends         |
| Validator Node | Produce blocks     | Pruned state | Network security      |

## Quick Start

### 1. Install Atlas

```bash
# Clone repository
git clone https://github.com/mapprotocol/atlas.git
cd atlas

# Build
make atlas

# Verify installation
./build/bin/atlas version
```

### 2. Initialize Node

```bash
# Create data directory
mkdir -p ~/.atlas

# Initialize with genesis
./build/bin/atlas --datadir ~/.atlas init genesis.json
```

### 3. Start Node

```bash
# Start full node
./build/bin/atlas --datadir ~/.atlas \
  --networkid 22776 \
  --syncmode full
```
