-Map states in Distributed mode support multiple sources for an array to iterate:
-
-* JSON array from the state input payload
-* objects in an S3 bucket and optional prefix
+`DistributedMap` supports various input source types to determine an array to iterate over:
+
+* JSON array from the state input
+  * By default, `DistributedMap` assumes whole state input is an JSON array and iterates over it:
+  ```json
+  [
+    "item1",
+    "item2"
+  ]
+  ```
+  ```ts
+  const distributedMap = new sfn.DistributedMap(this, 'DistributedMap');
+  distributedMap.itemProcessor(new sfn.Pass(this, 'Pass'));
+  ```
+  * When input source is present at a specific path in state input, then `itemsPath` can be utilised to configure the iterator source.
+  ```json
+  {
+    "distributedMapItemList": [
+      "item1",
+      "item2"
+    ]
+  }
+  ```
+  ```ts
+  const distributedMap = new sfn.DistributedMap(this, 'DistributedMap', {
+    itemsPath: '$.distributedMapItemList',
+  });
+  distributedMap.itemProcessor(new sfn.Pass(this, 'Pass'));
+  ```
+* Objects in a S3 bucket and optional prefix
+  * When `DistributedMap` is required to iterate over objects stored in a S3 bucket, then if required parameters like `bucket` are known while creating `StateMachine` (statically or at compile time), then an object of `S3ObjectsItemReader` (implementing `IItemReader`) can be passed to `itemReader` to configure the iterator source.
+  ```txt
+  my-bucket
+  |
+  +--item1
+  |
+  +--otherItem
+  |
+  +--item2
+  |
+  ...
+  ```
+  ```ts
+  import * as s3 from 'aws-cdk-lib/aws-s3';
+
+  const bucket = new s3.Bucket(this, 'Bucket', {
+    bucketName: 'my-bucket',
+  });
+
+  const distributedMap = new sfn.DistributedMap(this, 'DistributedMap', {
+    itemReader: new sfn.S3ObjectsItemReader({
+      bucket,
+      prefix: 'item',
+    }),
+  });
+  distributedMap.itemProcessor(new sfn.Pass(this, 'Pass'));
+  ```
+  * But if required parameters like `bucketName` are only known while starting execution of `StateMachine` (dynamically or at run-time) via state input, then an object of `S3ObjectsItemReaderPath` (implementing `IItemReaderPath`) can be passed to `itemReaderPath` to configure the iterator source.
+  ```json
+  {
+    "bucketName": "my-bucket",
+    "prefix": "item"
+  }
+  ```
+  ```ts
+  const distributedMap = new sfn.DistributedMap(this, 'DistributedMap', {
+    itemReaderPath: new sfn.S3ObjectsItemReaderPath({
+      bucketNamePath: '$.bucketName',
+      prefixPath: '$.prefix',
+    }),
+  });
+  distributedMap.itemProcessor(new sfn.Pass(this, 'Pass'));
+  ```
+  * Both `itemReader` and `itemReaderPath` are mutually exclusive. For example, if `bucket` is known at compile time but `prefix` is only known at run-time, then both cannot be used simultaneously.
 * JSON array in a JSON file stored in S3
+  * When `DistributedMap` is required to iterate over a JSON array stored in a JSON file in a S3 bucket, then if required parameters like `bucket` are known while creating `StateMachine` (statically or at compile time), then an object of `S3JsonItemReader` (implementing `IItemReader`) can be passed to `itemReader` to configure the iterator source.
+  ```txt
+  my-bucket
+  |
+  +--input.json
+  |
+  ...
+  ```
+  ```json
+  [
+    "item1",
+    "item2"
+  ]
+  ```
+  ```ts
+  import * as s3 from 'aws-cdk-lib/aws-s3';

-There are multiple classes that implement `IItemReader` that can be used to configure the iterator source.  These can be provided via the optional `itemReader` property. If S3 source needs to be configured dynamically at runtime using state input, then class implementations of `IItemReaderPath` can be utilised instead of `IItemReader`. These can be provided via the optional `itemReaderPath` property. Both `itemReader` and `itemReaderPath` are mutually exclusive. The default behavior, if both `itemReader` and `itemReaderPath` are omitted, is to use the input payload.
-
 Map states in Distributed mode also support writing results of the iterator to an S3 bucket and optional prefix.  Use a `ResultWriter` object provided via the optional `resultWriter` property to configure which S3 location iterator results will be written. The default behavior id `resultWriter` is omitted is to use the state output payload. However, if the iterator results are larger than the 256 kb limit for Step Functions payloads then the State Machine will fail.

 If you want to specify the execution type for the ItemProcessor in the DistributedMap, you must set the `mapExecutionType` property in the `DistributedMap` class. When using the `DistributedMap` class, the `ProcessorConfig.executionType` property is ignored.
