-### copilot-gpt4-service
-For this setup, an additional docker container will need to be setup.
-
-***It is necessary to obtain your token first.***
-
-Follow these instructions provided at **[copilot-gpt4-service#obtaining-token](https://github.com/aaamoon/copilot-gpt4-service#obtaining-copilot-token)** and keep your token for use within the service. Additionally, more detailed instructions for setting copilot-gpt4-service are available at the [GitHub repo](https://github.com/aaamoon/copilot-gpt4-service). 
-
-It is *not* recommended to use the copilot token obtained directly, instead use the `SUPER_TOKEN` variable. (You can generate your own `SUPER_TOKEN` with the OpenSSL command `openssl rand -hex 16` and set the `ENABLE_SUPER_TOKEN` variable to `true`)
-
-1. Once your Docker environment is ready and your tokens are generated, proceed with this Docker run command to start the service:
-    ```
-    docker run -d \
-      --name copilot-gpt4-service \
-      -e HOST=0.0.0.0 \
-      -e COPILOT_TOKEN=ghp_xxxxxxx \
-      -e SUPER_TOKEN=your_super_token \
-      -e ENABLE_SUPER_TOKEN=true \
-      --restart always \
-      -p 8080:8080 \
-      aaamoon/copilot-gpt4-service:latest
-    ```
-
-2. For Docker Compose users, use the equivalent yaml configuration provided below:
-    ```yaml
-    version: '3.8'
-    services:
-      copilot-gpt4-service:
-        image: aaamoon/copilot-gpt4-service:latest
-        environment:
-          - HOST=0.0.0.0
-          - COPILOT_TOKEN=ghp_xxxxxxx # Default GitHub Copilot Token, if this item is set, the Token carried with the request will be ignored. Default is empty.
-          - SUPER_TOKEN=your_super_token # Super Token is a user-defined standalone token that can access COPILOT_TOKEN above. This allows you to share the service without exposing your COPILOT_TOKEN. Multiple tokens are separated by commas. Default is empty.
-          - ENABLE_SUPER_TOKEN=true # Whether to enable SUPER_TOKEN, default is false. If false, but COPILOT_TOKEN is not empty, COPILOT_TOKEN will be used without any authentication for all requests.
-        ports:
-          - 8080:8080
-        restart: unless-stopped
-        container_name: copilot-gpt4-service
-    ```
-
-3. After setting up the Docker container for `copilot-gpt4-service`, you can add it to your `librechat.yaml` configuration. Here is an example configuration:
-    ```yaml
-    version: 1.0.1
-    cache: true
-    endpoints:
-      custom:
-        - name: "OpenAI via Copilot"
-          apiKey: "your_super_token"
-          baseURL: "http://[copilotgpt4service_host_ip]:8080/v1"
-          models:
-            default: ["gpt-4", "gpt-3.5-turbo"] # *See Notes
-          titleConvo: true
-          titleModel: "gpt-3.5-turbo"
-          summarize: true
-          summaryModel: "gpt-3.5-turbo"
-          forcePrompt: false
-          modelDisplayLabel: "OpenAI"
-          dropParams: ["user"]
-    ```
-    Replace `your_super_token` with the token you obtained following the instructions highlighted above and `[copilotgpt4service_host_ip]` with the IP of your Docker host. *****See Notes***
-
-    Restart Librechat after adding the needed configuration, and select `OpenAI via Copilot` to start using!
-
-    >Notes: 
-    > - *Only allowed models are `gpt-4` and `gpt-3.5-turbo`. 
-    > - **Advanced users can add this to their existing docker-compose file/existing docker network and avoid having to expose port 8080 (or any port) to the copilot-gpt4-service container.
