+# Example rechunking workflow
+
+1. Set up a Python environment
+```bash
+conda create --name virtualizarr-rechunk -y python=3.11
+conda activate virtualizarr-rechunk
+pip install -r requirements.txt
+```
+
+1. Set up cubed executor by following https://github.com/cubed-dev/cubed/blob/main/examples/lithops/aws/README.md
+```bash
+export CUBED_CONFIG=$(pwd)
+
+1. Build a runtime image for Cubed
+```bash
+export LITHOPS_CONFIG_FILE=$(pwd)/config.aws
+lithops runtime build -b aws_lambda -f Dockerfile_virtualizarr virtualizarr-runtime
+```
+
+1. Run the script
+```bash
+python cubed-rechunk.py
+```
+
+## Cleaning up
+To rebuild the Litops image, delete the existing one by running
+```bash
+lithops runtime delete -b aws_lambda -d virtualizarr-runtime
+```
