+# Get model from Hugging Face
+`python3 ./hug_model.py`
+
+You should now have a model in the current directory and model.bin symlinked to it for the subsequent Docker build and copy step. e.g.
+```
+docker $ ls -lh *.bin
+-rw-rw-r-- 1 user user 4.8G May 23 18:30 llama-7b.ggmlv3.q5_1.bin
+lrwxrwxrwx 1 user user   24 May 23 18:30 model.bin -> <downloaded-model-file>.q5_1.bin
+```
+- Note #1: Make sure you have enough disk space to d/l the model. As the model is then copied into the image you will need at least
+**TWICE** as much disk space as the size of the model:
+
+| Model |  Quantized size |
+|------:|----------------:|
+|    7B |            5 GB |
+|   13B |           10 GB |
+|   30B |           25 GB |
+|   65B |           50 GB |
+
+- Note #2: If you want to pass or tune additional parameters, customise `./start_server.sh` before running `docker build ...`
+
+# Use OpenBLAS (No NVidia GPU, defaults to `python:3-slim-bullseye` Docker base image)
+## Build:
+`docker build --build-arg -t openblas .`
+## Run:
+`docker run --cap-add SYS_RESOURCE -t openblas`
+
+# Use CuBLAS
+Requires NVidia GPU and Docker NVidia support (see https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/install-guide.html)
+## Build:
+`docker build --build-arg IMAGE=nvidia/cuda:12.1.1-devel-ubuntu22.04 -t opencuda .`
+## Run:
+`docker run --cap-add SYS_RESOURCE -t cublas`
