+* `vllm-sim`: Lightweight simulator for simple environments (defult).

+* `vllm-p2p`: Full vLLM with LMCache P2P support for enable KV-Cache aware routing

-```console
-export EPP_IMAGE="<YOUR_REGISTRY>/<YOUR_IMAGE>"
-export EPP_TAG="<YOUR_TAG>"
+```bash
+export HF_TOKEN="<HF_TOKEN>"

+**Warning**: For vllm mode, the default image uses llama3-8b. Make sure you have permission to access these files in their respective repositories.
+
+**Note:** The model can be replaced. See [Environment Configuration](#environment-configuration) for model settings.
+
 Once all this is set up, you can deploy the environment:
 
-```console
+```bash
 make environment.dev.kubernetes
 ```
 
 This will deploy the entire stack to whatever namespace you chose. You can test
 by exposing the inference `Gateway` via port-forward:

+
+#### Environment Configurateion
+
+**1. Setting the EPP image and tag:**
+
+You can optionally set a custom EPP image (otherwise, the default will be used):
+
+```bash
+export EPP_IMAGE="<YOUR_REGISTRY>/<YOUR_IMAGE>"
+export EPP_TAG="<YOUR_TAG>"
+```
+
+**2. Setting the vLLM image and tag:**
+
+Each vLLM mode has default image values, but you can override them:
+
+For `vllm-sim` mode:**
+
+```bash
+export VLLM_SIM_IMAGE="<YOUR_REGISTRY>/<YOUR_IMAGE>"
+export VLLM_SIM_TAG="<YOUR_TAG>"
+```
+
+For `vllm` and `vllm-p2p` modes:**
+
+```bash
+export VLLM_IMAGE="<YOUR_REGISTRY>/<YOUR_IMAGE>"
+export VLLM_TAG="<YOUR_TAG>"
 ```
 
+**3. Setting the model name and label:**
+
+You can replace the model name that will be used in the system.
+
+```bash
+export MODEL_NAME="${MODEL_NAME:-mistralai/Mistral-7B-Instruct-v0.2}"
+export MODEL_LABEL="${MODEL_LABEL:-mistral7b}"
+```
+
+It is also recommended to update the inference pool name accordingly so that it aligns with the models:
+
+```bash
+export POOL_NAME="${POOL_NAME:-vllm-Mistral-7B-Instruct}"
+```
+
+**4. Additional environment settings:**
