+# Deploying a JAX Model
+
+This README showcases how to deploy a simple ResNet model on Triton Inference Server. While Triton doesn't yet have a dedicated JAX backend, JAX/Flax models can be deployed using [Python Backend](https://github.com/triton-inference-server/python_backend). If you are new to Triton, it is recommended to watch this [getting started video](https://www.youtube.com/watch?v=NQDtfSi5QF4) and review [Part 1](https://github.com/triton-inference-server/tutorials/tree/main/Conceptual_Guide/Part_1-model_deployment) of the conceptual guide before proceeding. For the purposes of demonstration, we are using a pre-trained model provided by [flaxmodels](https://github.com/matthias-wright/flaxmodels).
+
+## Step 1: Set Up Triton Inference Server
+
+To use Triton, we need to build a model repository. The structure of the repository as follows:
+```
+model_repository
+|
++-- resnet50
+    |
+    +-- config.pbtxt
+    +-- 1
+        |
+        +-- model.py
+```
+For this example, we have pre-built the model repository. Next, we install the required dependencies and launch the Triton Inference Server.
+
+```
+# Replace the yy.mm in the image name with the release year and month
+# of the Triton version needed, eg. 22.12
+docker run --gpus=all -it --shm-size=256m --rm -p8000:8000 -p8001:8001 -p8002:8002 -v$(pwd):/workspace/ -v/$(pwd)/model_repository:/models nvcr.io/nvidia/tritonserver:<yy.mm>-py3 bash
+
+pip install --upgrade pip
+pip install --upgrade "jax[cuda]" -f https://storage.googleapis.com/jax-releases/jax_cuda_releases.html
+pip install --upgrade git+https://github.com/matthias-wright/flaxmodels.git
+
+```
+
+## Step 2: Using a Triton Client to Query the Server
+
+Let's breakdown the client application. First, we setup a connection with the Triton Inference Server.
+```
+client = httpclient.InferenceServerClient(url="localhost:8000")
+```
+Then we set the input and output arrays.
+```
+# Set Inputs
+input_tensors = [
+    httpclient.InferInput("image", image.shape, datatype="FP32")
+]
+input_tensors[0].set_data_from_numpy(image)
+
+# Set outputs
+outputs = [
+    httpclient.InferRequestedOutput("fc_out")
+]
+```
+Lastly, we query send a request to the Triton Inference Server.
+
+```
+# Query
+query_response = client.infer(model_name="resnet50",
+                                inputs=input_tensors,
+                                outputs=outputs)
+
+# Output
+out = query_response.as_numpy("fc_out")
+```
+
