 This is the AWS DynamoDB Adapter for next-auth. This package can only be used in conjunction with the primary next-auth package. It is not a standalone package.
 
-You need a table with a partition key `pk` and a sort key `sk`. Your table also needs a global secondary index named `GSI1` with `GSI1PK` as partition key and `GSI1SK` as sorting key. You can set whatever you want as the table name and the billing method.
+By default, the adapter expects a table with a partition key `pk` and a sort key `sk`, as well as a global secondary index named `GSI1` with `GSI1PK` as partition key and `GSI1SK` as sorting key. You can set whatever you want as the table name and the billing method.

+## Customize table structure
+
+You can configure your custom table structure by passing the `options` key to the adapter constructor:
+
+```
+const adapter = DynamoDBAdapter(client, {
+  tableName: "custom-table-name",
+  partitionKey: "custom-pk",
+  sortKey: "custom-sk",
+  indexName: "custom-index-name",
+  indexPartitionKey: "custom-index-pk",
+  indexSortKey: "custom-index-sk",
+})
