+# Prototype kerchunk grib aggregation & zarr IO for fast machine learning
+
+This is prototype code shared by Camus Energy to demonstrate possible optimizations for kerchunk and zarr based on
+our experience with machine learning in GCP.
+
+We hope to move much of the dynamic zarr store code into Kerchunk in the summer of 2024 with help from the community
+and an [IOOS GSOC intern](https://github.com/ioos/gsoc/issues/42).
+
+The zarr parallelization is more difficult to see a path to integration in zarr python 2, but hopefully will be a
+benchmark for performance in zarr python 3.
+
+## Setup
+
+```console
+mkdir venv
+python -m venv venv
+source  venv/bin/activate
+pip install -r requirements.txt
+
+jupyter-lab build
+
+jupyter-lab --port=${CAMUS_JUPYTER_PORT} --log_level=INFO --ip=0.0.0.0 --NotebookApp.notebook_dir=$(pwd -P)
+
+python -m unittest
+```
