# Building with LangChain4j

Java framework for integrating LLMs, RAG pipelines, tools, and agent workflows into JVM applications.

**Category:** RAG Frameworks
**Directory listing:** https://tokensand.com/tools/rag-frameworks/langchain4j
**Detected stack:** unknown
**Snippets derived from real docs:** no (fallback)

## Goal

I'm building a project with LangChain4j. Help me ship end-to-end in the smallest number of steps — hackathon speed, production-safe defaults. If any step below is ambiguous or the docs snippet is incomplete, ask me what I'm trying to build before writing code.

### Install
(No canonical install command detected — see docs links below.)

### First call
(No verified example detected — consult the official docs links before writing one.)

## Docs links
- [Official Docs](https://docs.langchain4j.dev/intro)
- [GitHub](https://github.com/langchain4j/langchain4j)
- [Website](https://docs.langchain4j.dev/)


## Your task
1. Read the install and first-call blocks above. Write a minimal runnable starter in the detected stack (unknown).
2. Call out any secrets I'll need (API keys, env vars) and how to get them.
3. Suggest one "next step" that would make this project demo
