 #### AWS S3 & DynamoDB
-Take a look at our [s3-dynamodb setup](./aws_storage.md)
+
+##### Example config via yaml file
+```yaml
+schema_config:
+  configs:
+  - from: 0
+    store: dynamo
+    object_store: s3
+    schema: v9
+    index:
+      prefix: dynamodb_table_name
+      period: 0
+storage_config:
+  aws:
+    s3: s3://access_key:secret_access_key@region/bucket_name
+    dynamodbconfig:
+      dynamodb: dynamodb://access_key:secret_access_key@region
+```
+
+###### S3 
+
+Loki is using S3 as object storage. It stores log within directories based on
+[`OrgID`](./operations.md#Multi-tenancy). For example, Logs from org `faker`
+will stored in `s3://BUCKET_NAME/faker/`.
+
+The S3 configuration is setup with url format: `s3://access_key:secret_access_key@region/bucket_name`.
+
+###### Dynamo DB
+
+Loki uses dynamodb for the index storage. It is used for querying logs, make
+sure you adjuest your throughput to your usage.
+
+DynamoDB access is very similar to S3, however you do not need to specific a
+table name in the storage section.  You will need to set the table name for
+`index.prefix` inside schema config section.
+
+You can setup DynamoDB by yourself, or have `table-manager` setup for you.
+You can find out more info about table manager at
+[cortex project](https://github.com/cortexproject/cortex)(https://github.com/cortexproject/cortex).
+There is an example table manager deployment inside the ksonnet deployment method.  You can find it [here](../production/ksonnet/loki/table-manager.libsonnet)
+
+####### Manual setup
+You will need to setup primary index key `h`(string) and `r`(binary) as the sort
+key. Make sure adjust your throughput base on your usage.
