# Getting Started

Welcome to LangGraph4j! This guide will help you understand the core concepts of LangGraph4j, install it, and build your first application.

---

## Installation

To use LangGraph4j in your project, you need to add it as a dependency.

**Maven:**

Make sure you are using Java 17 or later.

**Latest Stable Version (Recommended):**
```xml
<properties>
    <langgraph4j.version>1.8.20</langgraph4j.version> 
</properties>


<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>org.bsc.langgraph4j</groupId>
      <artifactId>langgraph4j-bom</artifactId>
      <version>${langgraph4j.version}</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

<dependencies>
    <dependency>
        <groupId>org.bsc.langgraph4j</groupId>
        <artifactId>langgraph4j-core</artifactId>
    </dependency>
    
</dependencies>
```
*(Note: Always check the [Maven Central Repository](https://central.sonatype.com/search?q=g%3Aorg.bsc.langgraph4j) for the latest version number.)*

**Development Snapshot Version:**
If you want to use the latest unreleased features, you can use a snapshot version.
```xml
<dependency>
    <groupId>org.bsc.langgraph4j</groupId>
    <artifactId>langgraph4j-core</artifactId>
    <version>1.8.20</version> 
</dependency>
```
You might need to configure your `settings.xml` or `pom.xml` to include the Sonatype OSS snapshots repository:
```xml
<repositories>
    <repository>
        <id>sonatype-oss-snapshots</id>
        <url>https://central.sonatype.com/repository/maven-snapshots</url>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>
</repositories>
```
