+
+   2. Create a new bucket on Google Cloud Storage.
+      $ mc {{.Name}} gcs/miniocloud

+   4. Create a new bucket on Amazon S3 cloud storage in region ‘us-west-2’.
+      $ mc {{.Name}} --region=us-west-2 s3/myregionbucket
+
+   5. Create a new directory including its missing parents (equivalent to ‘mkdir -p’).
+      $ mc {{.Name}} /tmp/this/new/dir1
+
+   6. Create multiple directories including its missing parents (behavior similar to ‘mkdir -p’).
