## Installation

Install the extractor:

```bash
npm install @lightfeed/extractor @langchain/openai
npm install @lightfeed/extractor
```

Install the LangChain integration package for your chosen provider. `@langchain/core` is a peer dependency — it's shared automatically:
Then install the LLM provider you want to use:

```bash
# OpenAI
npm install @lightfeed/extractor @langchain/openai
npm install @langchain/openai

# Google Gemini
npm install @lightfeed/extractor @langchain/google-genai
npm install @langchain/google-genai

# Anthropic
npm install @lightfeed/extractor @langchain/anthropic
npm install @langchain/anthropic

# Ollama (local models)
npm install @lightfeed/extractor @langchain/ollama
npm install @langchain/ollama
```

`@langchain/core` will be installed automatically as a peer dependency.
