+### Local cloud storage environment
+
+You can run an S3 API compatible storage locally with [minio](https://min.io/).
+
+You must have [docker compose](https://docs.docker.com/compose/) installed on your workstation.
+
+Start the local cloud environment:
+```
+make start-cloud-storage
+```
+There is a sample registry configuration file that lets you point the registry to the started storage:
+```
+AWS_ACCESS_KEY=distribution \
+        AWS_SECRET_KEY=password \
+        AWS_REGION=us-east-1 \
+        S3_BUCKET=images-local \
+        S3_ENCRYPT=false \
+        REGION_ENDPOINT=http://127.0.0.1:9000 \
+        S3_SECURE=false \
+./bin/registry serve tests/conf-local-cloud.yml
+```
+Stop the local storage when done:
+```
+make stop-cloud-storage
+```
