-Dimensions can have multiple values for TSV and CSV data. To specify the delimiter for a multi-value dimension, set the `listDelimiter` in the `parseSpec`.

-JSON data can contain multi-value dimensions as well. The multiple values for a dimension must be formatted as a JSON array in the ingested data. No additional `parseSpec` configuration is needed.

-Apache Druid supports "multi-value" string dimensions. These are generated when an input field contains an

+This document describes filtering and grouping behavior for multi-value dimensions. For information about the internal representation of multi-value dimensions, see
+[segments documentation](../design/segments.md#multi-value-columns). Examples in this document
 are in the form of [native Druid queries](querying.md). Refer to the [Druid SQL documentation](sql.md) for details
 about using multi-value string dimensions in SQL.
 
+## Overview
+
+At ingestion time, Druid can detect multi-value dimensions and configure the `dimensionsSpec` accordingly. It detects JSON arrays or CSV/TSV fields as multi-value dimensions.
+
+For TSV or CSV data, you can specify the multi-value delimiters using the `listDelimiter` field in the `parseSpec`. JSON data must be formatted as a JSON array to be ingested as a multi-value dimension. JSON data does not require `parseSpec` configuration.
+
+The following shows an example multi-value dimension named `tags` in a `dimensionsSpec`:
+
+```
+"dimensions": [
+  {
+    "type": "string",
+    "name": "tags",
+    "multiValueHandling": "SORTED_ARRAY",
+    "createBitmapIndex": true
+  }
+],
+```
+
+By default, Druid sorts values in multi-value dimensions. This behavior is controlled by the `SORTED_ARRAY` value of the `multiValueHandling` field. Alternatively, you can specify multi-value handling as:
+
+* `SORTED_SET`: results in the removal of duplicate values
+* `ARRAY`: retains the original order of the values
+
+See [Dimension Objects](../ingestion/index.md#dimension-objects) for information on configuring multi-value handling.
+
+
