 ### Use
 
+If you see unexpected errors in the console, make sure `daemon.py` is running or else the required data will be missing from Redis. You may need to wait a few minutes for the daemon to populate the database.
 
+Flask may give unusual errors when running `python server.py`. I think this is coming from Flask-Socket. Running with Gunicorn seems to fix the issue: `gunicorn -b :5000 --worker-class gevent server:app`

+**A Docker container for running VLLM on Paperspace Gradient notebooks.**
+
+### Running
+
+1. In Paperspace, create a new notebook.
+2. Click `Start from Scratch`.
+3. Select your GPU and set the auto-shutdown timeout to 6 hours.
+4. Click the `View Advanced Options` button at the bottom of the page. Enter these details in the form that appears:
+    - Container Name: `cyberes/vllm-paperspace:latest`
+    - Container Command: `/app/start.sh`
+5. Start the notebook. It may take up to five minutes for them to pull and start the custom image.
+6. Once the container is started, open the log viewer by clicking the icon in the bottom left of the screen. You should see errors from rathole and VLLM as a result of the blank config files. The container will create a new directory in your mounted
+   storage: `/storage/vllm/`.
+7. Enter your rathole client config in `/storage/vllm/rathole-client.toml`. If you need a visual text editor, first link the directory back to the Jupyter home: `ln -s /storage/vllm /notebooks`
+8. Restart rathole with `supervisorctl restart rathole` and then view the log: `tail -f /var/log/app/rathole.log`. If you see lines that start with `INFO` and end with `Control channel established`, rathole has connected and is working. Error mesasges will begin
+   with `ERROR`.
+9. Download an AWQ quantization from [TheBloke](https://huggingface.co/TheBloke) to `/storage/vllm/models/`.
+10. Enter your VLLM commandline args in `/storage/vllm/cmd.txt`. You need to set `--model` to the path of the model you want to load.
+11. Restart VLLM with `supervisorctl restart vllm` and then view the log: `tail -f /var/log/app/vllm.log`. It may take up to three minutes to load. When you see the line:
+   ```
+  INFO:     Uvicorn running on http://0.0.0.0:7000 (Press CTRL+C to quit)
+   ```
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;VLLM is running and ready for queries.
+
+12. In `/notebooks` (the home directory of Jupyter), the notebook `idle.ipynb` will automatically be created. Run this notebook so Paperspace does not shut down your machine due to "inactivity". You **must** keep the running notebook open in a
+    browser tab.
+
+### Building
+
+You **must** have a GPU attached to your system when building the container (required for building VLLM).
+
+1. Install the [NVIDIA Container Toolkit](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html) and CUDA 11.8.
+2. `bash build-docker.sh`
+
+To run the container on your local machine:
+
+```bash
+sudo docker run -it --shm-size 14g --gpus all -v /home/user/testing123/notebooks:/notebooks -v /home/user/testing123/storage:/storage -p 8888:8888 cyberes/vllm-paperspace:latest
+```
+
+You will need to create a directory to mount inside the container (for example: `/home/user/testing123/`). Within this should be the folder `models` that holds the model to load, `rathole-client.toml`, and `cmd.txt`.
+
+If you need to debug something, you can start a shell inside the container:
+
+```bash
+sudo docker run -it --shm-size 14g --gpus all -v /home/user/testing123/notebooks:/notebooks -v /home/user/testing123/storage:/storage -p 8888:8888 --entrypoint bash cyberes/vllm-paperspace:latest
+```
