 Create new buckets like:
 
-    mc mb sandcrawler/grobid
+    mc mb cluster/sandcrawler-qa
+
+## Development
+
+Run minio server locally, with non-persisted data:
+
+    docker run -p 9000:9000 minio/minio server /data
+
+Credentials are `minioadmin:minioadmin`. Install `mc` client utility, and
+configure:
+
+    mc config host add localhost http://localhost:9000 minioadmin minioadmin
+
+Then create dev bucket:
+
+    mc mb --ignore-existing localhost/sandcrawler-dev
+
+A common "gotcha" with `mc` command is that it will first look for a local
+folder/directory with same name as the configured remote host, so make sure
+there isn't a `./localhost` folder.
