## Getting Started

To incorporate Quarkus Langchain4j into your Quarkus project, add the following Maven dependency:

```xml
<dependency>
    <groupId>io.quarkiverse.langchain4j</groupId>
    <artifactId>quarkus-langchain4j-openai</artifactId>
    <version>{latest-version}</version>
</dependency>
```

or, to use hugging face:

```xml
<dependency>
    <groupId>io.quarkiverse.langchain4j</groupId>
    <artifactId>quarkus-langchain4j-huggingface</artifactId>
    <version>{latest-version}</version>
</dependency>
```

Make sure to replace `{latest-version}` with the most recent release version available on [Maven Central](https://search.maven.org/artifact/io.quarkiverse.langchain4j/quarkus-langchain4j).
