+
+## Welcome to Groq! 🚀
+
+At Groq, we've developed the world's first Language Processing Unit™, or LPU. The Groq LPU has a deterministic, single core streaming architecture that sets the standard for GenAI inference speed with predictable and repeatable performance for any given workload.
+
+Beyond the architecture, our software is designed to empower developers like you with the tools you need to create innovative, powerful AI applications. With Groq as your engine, you can:
+
+* Achieve uncompromised low latency and performance for real-time AI and HPC inferences 🔥
+* Know the exact performance and compute time for any given workload 🔮
+* Take advantage of our cutting-edge technology to stay ahead of the competition 💪
+
+Want more Groq? Check out our [website](https://groq.com) for more resources and join our [Discord community](https://discord.gg/JvNsBDKeCG) to connect with our developers!
+
+
+## Installation and Setup
+Install the integration package:
+
+```bash
+pip install langchain-groq
+```
+
+Request an [API key](https://wow.groq.com) and set it as an environment variable
+
+```bash
+export GROQ_API_KEY=gsk_...
+```
+
+## Chat Model
+See a [usage example](https://python.langchain.com/docs/integrations/chat/groq).
+
+## Development
+
+To develop the `langchain-groq` package, you'll need to follow these instructions:
+
+### Install dev dependencies
+
+```bash
+poetry install --with test,test_integration,lint,codespell
+```
+
+### Build the package
+
+```bash
+poetry build
+```
+
+### Run unit tests
+
+Unit tests live in `tests/unit_tests` and SHOULD NOT require an internet connection or a valid API KEY.  Run unit tests with
+
+```bash
+make tests
+```
+
+### Run integration tests
+
+Integration tests live in `tests/integration_tests` and require a connection to the Groq API and a valid API KEY.
+
+```bash
+make integration_tests
+```
+
+### Lint & Format
+
+Run additional tests and linters to ensure your code is up to standard.
+
+```bash
+make lint spell_check check_imports
+```
