+
+## Description
+
+This model is intended to be used as an accelerator for [llama3 8b (instruct)](https://huggingface.co/meta-llama/Meta-Llama-3-8B-Instruct) and takes inspiration 
+from the Medusa speculative decoding architecture. This accelerator modifies the MLP into a multi-stage MLP, where each stage predicts 
+a single token in the draft based on both a state vector and sampled token
+from the prior stage (the base model can be considered stage 0).
+The state vector from the base model provides contextual information to the accelerator, 
+while conditioning on prior sampled tokens allows it to produce higher-quality draft n-grams.
+
+Note: The underlying MLP speculator is a generic architecture that can be trained with any generative model to accelerate inference. 
+Training is light-weight and can be completed in only a few days depending on base model size and speed.

+## Samples
+
+_Note: For all samples, your environment must have access to cuda_
+
+### Production Server Sample
+
+*To try this out running in a production-like environment, please use the pre-built docker image:*
+
+#### Setup
+
+```bash
+HF_HUB_CACHE=/hf_hub_cache
+chmod a+w $HF_HUB_CACHE
+HF_HUB_TOKEN="your huggingface hub token"
+TGIS_IMAGE=quay.io/wxpe/text-gen-server:main.ee927a4
+
+docker pull $TGIS_IMAGE
+
+# optionally download llama3-8b-instruct if the weights do not already exist
+docker run --rm \
+    -v $HF_HUB_CACHE:/models \
+    -e HF_HUB_CACHE=/models \
+    -e TRANSFORMERS_CACHE=/models \
