+# ReAct Agent Application
+
+This recipe demonstrates the ReAct (Reasoning and Acting) framework in action through a music exploration application. ReAct enables AI to think step-by-step about tasks, take appropriate actions, and provide reasoned responses. The application shows how ReAct can be used to create an intelligent music discovery assistant that combines reasoning with Spotify API interactions.
+
+The application utilizes [`llama-cpp-python`](https://github.com/abetlen/llama-cpp-python) for the Model Service and integrates with Spotify's API for music data. The recipe uses [Langchain](https://python.langchain.com/docs/get_started/introduction) for the ReAct implementation and [Streamlit](https://streamlit.io/) for the UI layer.
+
+## Spotify API Access
+To use this application, you'll need Spotify API credentials:
+- Create a Spotify Developer account
+- Create an application in the Spotify Developer Dashboard
+- Get your Client ID and Client Secret
+
+These can be provided through environment variables or the application's UI.
+
+## Try the ReAct Agent Application
+The [Podman Desktop](https://podman-desktop.io) [AI Lab Extension](https://github.com/containers/podman-desktop-extension-ai-lab) includes this recipe among others. To try it out, open `Recipes Catalog` -> `ReAct Agent` and follow the instructions to start the application.
+
+# Build the Application
+
+The rest of this document will explain how to build and run the application from the terminal, and will
+go into greater detail on how each container in the Pod above is built, run, and 
+what purpose it serves in the overall application. All the recipes use a central [Makefile](../../common/Makefile.common) that includes variables populated with default values to simplify getting started. Please review the [Makefile docs](../../common/README.md), to learn about further customizing your application.
+
+
+This application requires a model, a model service and an AI inferencing application.

+
+
+## Quickstart
+To run the application with pre-built images from `quay.io/ai-lab`, use `make quadlet`. This command
+builds the application's metadata and generates Kubernetes YAML at `./build/chatbot.yaml` to spin up a Pod that can then be launched locally.
+Try it with:
+
+```
+make quadlet
+podman kube play build/chatbot.yaml
+```
+
+This will take a few minutes if the model and model-server container images need to be downloaded. 
+The Pod is named `chatbot`, so you may use [Podman](https://podman.io) to manage the Pod and its containers:
+
+```
+podman pod list
+podman ps
+```
+
+Once the Pod and its containers are running, the application can be accessed at `http://localhost:8501`. However, if you started the app via the podman desktop UI, a random port will be assigned instead of `8501`. Please use the AI App Details `Open AI App` button to access it instead. 
+Please refer to the section below for more details about [interacting with the chatbot application](#interact-with-the-ai-application).
+
+To stop and remove the Pod, run:
+
+```
+podman pod stop chatbot
+podman pod rm chatbot
+```
+
+## Download a model
+
+If you are just getting started, we recommend using [granite-7b-lab](https://huggingface.co/instructlab/granite-7b-lab). This is a well
+performant mid-sized model with an apache-2.0 license. In order to use it with our Model Service we need it converted
+and quantized into the [GGUF format](https://github.com/ggerganov/ggml/blob/master/docs/gguf.md). There are a number of
+ways to get a GGUF version of granite-7b-lab, but the simplest is to download a pre-converted one from
+[huggingface.co](https://huggingface.co) here: https://huggingface.co/instructlab/granite-7b-lab-GGUF.
+
+The recommended model can be downloaded using the code snippet below:
+
+```bash
+cd ../../../models
+curl -sLO https://huggingface.co/instructlab/granite-7b-lab-GGUF/resolve/main/granite-7b-lab-Q4_K_M.gguf
+cd ../recipes/natural_language_processing/chatbot
+```
+
+_A full list of supported open models is forthcoming._  
+
+
+## Build the Model Service
+
+The complete instructions for building and deploying the Model Service can be found in the
+[llamacpp_python model-service document](../../../model_servers/llamacpp_python/README.md).
+
+The Model Service can be built from make commands from the [llamacpp_python directory](../../../model_servers/llamacpp_python/).
+
+```bash
+# from path model_servers/llamacpp_python from repo containers/ai-lab-recipes
+make build
+```
+Checkout the [Makefile](../../../model_servers/llamacpp_python/Makefile) to get more details on different options for how to build.
+
+## Deploy the Model Service
+
+The local Model Service relies on a volume mount to the localhost to access the model files. It also employs environment variables to dictate the model used and where its served. You can start your local Model Service using the following `make` command from `model_servers/llamacpp_python` set with reasonable defaults:
+
+```bash
+# from path model_servers/llamacpp_python from repo containers/ai-lab-recipes
+make run
+```
+
+## Build the AI Application
+
+The AI Application can be built from the make command:
+
+```bash
+# Run this from the current directory (path recipes/natural_language_processing/chatbot from repo containers/ai-lab-recipes)
+make build
+```
+
+## Deploy the AI Application
+
+Make sure the Model Service is up and running before starting this container image. When starting the AI Application container image we need to direct it to the correct `MODEL_ENDPOINT`. This could be any appropriately hosted Model Service (running locally or in the cloud) using an OpenAI compatible API. In our case the Model Service is running inside the Podman machine so we need to provide it with the appropriate address `10.88.0.1`. To deploy the AI application use the following:
+
+```bash
+# Run this from the current directory (path recipes/natural_language_processing/chatbot from repo containers/ai-lab-recipes)
+make run 
+```
+
+## Interact with the AI Application
+
+Everything should now be up an running with the chat application available at [`http://localhost:8501`](http://localhost:8501). By using this recipe and getting this starting point established, users should now have an easier time customizing and building their own LLM enabled chatbot applications.   
+
+## Embed the AI Application in a Bootable Container Image
+
+To build a bootable container image that includes this sample chatbot workload as a service that starts when a system is booted, run: `make -f Makefile bootc`. You can optionally override the default image / tag you want to give the make command by specifying it as follows: `make -f Makefile BOOTC_IMAGE=<your_bootc_image> bootc`.
+
+Substituting the bootc/Containerfile FROM command is simple using the Makefile FROM option.
+
+```bash
+make FROM=registry.redhat.io/rhel9/rhel-bootc:9.4 bootc
+```
+
+Selecting the ARCH for the bootc/Containerfile is simple using the Makefile ARCH= variable.
+
+```
+make ARCH=x86_64 bootc
+```
+
+The magic happens when you have a bootc enabled system running. If you do, and you'd like to update the operating system to the OS you just built
+with the chatbot application, it's as simple as ssh-ing into the bootc system and running:
+
+```bash
+bootc switch quay.io/ai-lab/chatbot-bootc:latest
+```
+
+Upon a reboot, you'll see that the chatbot service is running on the system. Check on the service with:
+
+```bash
+ssh user@bootc-system-ip
+sudo systemctl status chatbot
+```
+
+### What are bootable containers?
+
+What's a [bootable OCI container](https://containers.github.io/bootc/) and what's it got to do with AI?
+
+That's a good question! We think it's a good idea to embed AI workloads (or any workload!) into bootable images at _build time_ rather than
+at _runtime_. This extends the benefits, such as portability and predictability, that containerizing applications provides to the operating system.
+Bootable OCI images bake exactly what you need to run your workloads into the operating system at build time by using your favorite containerization
+tools. Might I suggest [podman](https://podman.io/)?
+
+Once installed, a bootc enabled system can be updated by providing an updated bootable OCI image from any OCI
+image registry with a single `bootc` command. This works especially well for fleets of devices that have fixed workloads - think
+factories or appliances. Who doesn't want to add a little AI to their appliance, am I right?
+
+Bootable images lend toward immutable operating systems, and the more immutable an operating system is, the less that can go wrong at runtime!
+
+#### Creating bootable disk images
+
+You can convert a bootc image to a bootable disk image using the
+[quay.io/centos-bootc/bootc-image-builder](https://github.com/osbuild/bootc-image-builder) container image.
+
+This container image allows you to build and deploy [multiple disk image types](../../common/README_bootc_image_builder.md) from bootc container images.
+
+Default image types can be set via the DISK_TYPE Makefile variable.
+
+`make bootc-image-builder DISK_TYPE=ami`
