 # Big Bang Package: Object Storage
 
-If your package supports using object storage (e.g. S3 buckets), it must be integrated with Big Bang's storage configuration.  This document will detail how to do this.
+If the package supports object storage (e.g. S3 buckets), it must be integrated with Big Bang's storage configuration.  This document will detail how to do this.
+
+In BigBang MinIO is  a consistent, performant and scalable object store for the cloud strategies. Minio is Kubernetes-native by design and S3 compatible 
 
 ## Prerequisites
 
-TBD
+Addon Minio is enabled at the BigBang, alternatively you have an existing Minio Instance \
+AWS S3 AccessKey and SecretKey \
+Existing S3 bucket  for the deployment 
 
 ## Integration
 
+Minio object storage can be integrated in bigbang with the  entries in  bigbang value.yaml at the package level. 
+
+NOTE: Some packages may have in-built object storage and the implementation may vary.
+
+```yaml
+{{- if or .Values.addons.minio.enabled}}
+minio:
+  enabled: {{ .Values.<chartname>.minio.enabled }}
+    disableSSL: false
+    endpoint: {{  .Values.<chartname>.minio.endpoint }}
+    accessKey: {{   .Values.<chartname>.minio.accessKey }}
+    secretKey: {{   .Values.<chartname>.minio.secretKey }}
+    bucketName: {{   .Values.<chartname>.minio.bucketName }}
+{{ end }}

+```
